To conscientiously implement the CPC Central Committee and State Council "on the overall strengthening of environmental protection and resolutely fight pollution prevention advice tough fight" and "the State Council on the issuance of three-year winning the Battle of the blue sky plan of action," the spirit, boiler emissions control, prevention and treatment air pollution, the State environmental Protection Department to develop "boiler air pollutant emission standards." In order to further the implementation of air pollution control operations, all regions at the same time meet the national standard, but also have introduced a more stringent local standards.
From the implementation of the Beijing gas nitrogen oxide emission standards for boilers began 30mg, emissions from gas-fired boiler has been of great concern, expand around the "coal to gas" action, so that gas such devices become the most countries to promote clean energy boiler.
The transformation of the current common low nitrogen boiler, there are three main measures: (1) replacement of boilers, (2) replace the burner (3) in the boiler flue gas treatment.
Controlling the nitrogen oxide generated from the source, the most advanced technology on the market today is the use of flue gas recirculation techniques and FGR premix combustion gas boiler technology, both having different focus, low nitrogen emissions boiler.
Replace the boiler burner, renovation and debugging, and the impact on the safety performance of the resulting boiler, burner unit by the responsible manufacturer or his authorized. Beijing Bureau of Quality and Technical Supervision, Beijing Municipal Environmental Protection Bureau issued the "Notice on the transformation of the low - NOx combustion safety risk warning" states: the transformation of low-nitrogen combustion boiler diverse, complex technology, to protect the smooth implementation of the work of reform, effective prevent security risks, prevent accidents, analysis and appraisal by experts, it is not recommended comprehensive safety, environmental factors, the following recommendations:
Nitrogen oxides have been generated by some means and then reduced to nitrogen, the main fuel reburning, selective catalytic reduction, selective non-catalytic reduction. But in the actual monitoring, the nitrogen oxide emissions controllability is poor.
The transformation of low nitrogen gas boiler is a need for long-term adherence and actively manage the work, under the premise to meet the national standards, do specifically address the specific circumstances, not blindly, careless handling, to adopt plans, goals, ideas implementation, to achieve a comprehensive upgrade gas boiler.
Fuel oil combustion process differs from the process industry Industrial Combustion fuel oil-fired boilers for industrial oil fired boilers and industrial boilers, having a certain temperature and pressure injected into the furnace through the nozzle is atomized into fine droplets, and then absorbs heat in the furnace, vertical oil-fired boiler, surface gradually vaporized into oil, mixed with intake air in the furnace, form a combustible mixture. The combustible mixture continues endotherm temperature reached ignition ignition combustion. Fuel amount, air amount and the amount of the composite has a one to one relationship of steam, it is necessary according to the load amount of steam required to control the amount of fuel and air supply, but also by the wind furnace pressure control apparatus. Different oil-fired boiler with a different point of industrial coal-fired boilers point of industrial boiler fuel industry and industrial coal-fired boilers. PM2.5 pollution damage to the environment led some coal-fired boilers industrial boilers is facing new boiler renovation or change of situation, which makes oil-fired boiler to become the darling of the market. Oil-fired boiler with a coal-fired boiler in comparison with structurally quite different purposes, as follows: (1) injecting fuel into the boiler furnace through the burner, combustion chamber without using fire grate facilities; (2) Since the oil, gas did not produce combustion ash, it is no oil or gas boiler slag and slag outlet device; (3) injecting a gas or oil furnace materialized, if mixed with air or flame within a certain range, is easy to form an explosive gas, Thus fuel (gas) required automated combustion boiler system, comprising a flame monitoring, flame protection, explosion-proof safety; (4) Since the oil, gas calorific value is much larger than the calorific value of coal, so the thermal strength than fired furnace high multi-furnace, so relatively small and the capacity of the boiler with coal-fired boilers, compact, small footprint; combustion process (5) fuel (gas) is suspended in a boiler furnace, the furnace is provided so its before and after the arch, the furnace structure is very simple. Meter manufacturing, Supervision, Inspection and the main characteristics of biomass fuel boilers  protection devices and control systems introduced a biomass fired boiler biomass fuel boilers are in strict accordance with "Steam Boiler Safety Supervision", JB / T10094-2002 "general industrial boilers technical conditions ", JB / T1619-2002" shell boiler body manufacturing technology, "execution, ensure long-term security and stability of the boilers. Body is a shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in the combustion chamber a slight positive pressure, stretched stretch, combustion heat load is low, less NOx emissions of harmful substances. Waveform furnace and threaded pipe structure that improves the strength, but also to meet the needs of each portion of the thermal expansion. Master butt welds are connected, and by X-ray and ultrasonic nondestructive testing, to ensure the welding quality to meet national requirements. Boiler water volume and large air space, adaptable load capacity. Design reasonable pot, with water vapor to ensure that less than 4%, to meet user requirements for higher quality steam. Using the new insulation materials, light weight, low heat loss, good insulation properties. Water level alarm stainless steel rods as electrodes, an insulating material as polytetrafluoroethylene. Inserted from above, linked to pollution easy, reliable, and long service life. Before and after the smoke box is hinged, can easily open, repair and maintenance quick and easy maintenance. Adjusting the oxygen content (optional): The system can successfully monitor the oxygen content in the flue gas, and transfer the data to the real-time control systems, intelligent analysis by a computer, the automatic adjustment device stoichiometric combustion, it is in real-time good working shape, combustion efficiency is greatly improved, which can significantly reduce fuel consumption. Biomass fuel boiler operation timing of the protection device, the operation of the control system by the timer, the system automatically enters the work or off duty. The control system may be provided multiple sets of the timing period within 24 hours. Any period of time in a group of a plurality of sets of timing of the current time period, the system enters the working state. Work within the timing period, the status screen is displayed automatically. In the period of time in commuting to work outside the state. Each group comprises a turn-on time period (hour, minutes) and a closing time (hours, minutes) may be set or modified when the three control period, divided by the setting operation and the current time. The user can set different time different temperature ranges.
6 tons adjusting a combustion gas 15 tons szl coal fired steam boiler, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
Horizontal hot water boiler a few precautions, overpressure accident 1 boiler, 15 tons szl coal fired steam boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" is still working pressure safety valve l high. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, steam boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
