The design of the boiler room fire interval is how much? Section 13.1.1 boiler fire hazard classification and fire rating should meet the following requirements: a room, boiler production plant belongs to class D, to the industrial fire tube fired steam boiler rated evaporation 4t / h, when the hot water boiler rated output is greater than 2.8MW, boiler room building fire resistance rating of not less than two; steam boiler equal to or less than the rated evaporation 4t / h, when the hot water boiler is equal to or less than the rated output 2.8MW, between the boiler building fire resistance rating of not less than three; II. when the inter-tank, and a pump room between the oil heater are class C production plant, its construction fire resistance rating of not less than two, disposed within said room between the auxiliary boiler room, a room should be set apart from other firewall; III. between the gas regulator production plant belonging to Group a, which is not less than two building fire rating, should be provided between the boiler room and the immediate neighborhood regulator firewall spaced boiler room, which doors open outwards and should not be passed directly the boiler room, the ground should not spark floor. Referring again to the provisions of Article 5.2.2 GB50016-2006 "architectural design code for fire protection," according to fire resistance rating.
In early 2019, Xingtai City, Hebei Province, air pollution control for industrial enterprises, to develop the relevant regulations. Mainly for the protection and improvement of the atmospheric environment, prevention of air pollution and protect public health, promote the construction of ecological civilization, and promote the development of sustainable economic and social development goals.
First, according to the national industrial policy, Hebei Province, strict control of new construction, renovation, expansion of iron and steel, cement, plate glass, synthetic chemical pharmaceuticals, non-ferrous metal smelting, building ceramics, chemicals and other industrial projects.
Iron and steel, cement, plate glass, synthetic chemical pharmaceuticals, non-ferrous metal smelting, building ceramics, chemicals and other key industries cleaner production audits in accordance with law, the use of advanced clean production technologies, processes and equipment.
Urban area, high above emissions in key industries around the ecological red line in the control area, high-pollution projects should be gradual relocation, renovation or restructuring, exit.
Air pollution insurance companies encourage heavy environmental pollution liability insurance.
Second, the city and county (city, district) people's government may take their overall economic efficiency sorting, etc., specific measures for serious overcapacity in the industry, the atmosphere of heavily polluting enterprises, the differential credit, the difference is the price of water, different gas prices, punitive tariffs, etc. .
Third, the industrial concentration area should develop cogeneration and district heating, heat unified solution. In addition to centralized district heating and combined heat and power, waste incineration and biomass power generation project, the city's ban on new or expanded high-polluting fuel for power plants, ban high-pollution fuel combustion zone ban on new construction, expansion-owned high-polluting fuel boiler heat supporting units supply station.
Boiler for industrial production should reach atmospheric pollutant emission standards set by the State and the boiler Hebei and marked fuel requirements and atmospheric pollutant emission control targets.
Fourth, industrial enterprises store coal, cement, lime, sand and other materials easy to produce pollution should take sealed enclosure, cover, cleaning, watering and other measures to prevent dust pollution.
Fifth, iron and steel, petroleum, nonferrous metals, electric power, coke, construction materials, metallurgy, chemical and other industrial enterprises in the production process emissions of dust, nitrogen oxides and sulfides, shall adopt cleaner production processes, supporting the construction dust removal, desulfurization, denitration apparatus, or take other measures to control the emission of air pollutants like transformation.
Greater than 65t / h industrial boiler of what air pollutant emission standards should be executed? A: The State Environmental Protection Administration, Central Division-standard  No. 012 document pointed out that the emergence of a small number of parameters currently higher than GB1921-80 "industrial industrial fire tube fired steam boiler parameters Series" and GB3166-82 "hot water boiler parameters Series" layer burning, stoker boiler, regardless of its use Zanan GB1327-91 execution. Therefore> 65t / h or more (except coal, circulating fluidized bed, and fuel, gas fired boilers) industrial boilers should be performed "boiler air pollutant emission standards."
Coal-fired boilers to gas boilers benefits and precautions With the rapid development of national energy-saving environmental protection, the traditional coal-fired boiler can not meet the needs of the times. Therefore, the coal-fired boiler biomass boiler or gas boiler has become in many boiler user's choice. Before the transformation, to understand the difference between .1 and gas boiler fired boiler. Circulating fluidized bed combustion boiler fired by coal crushing device fluidized combustion process, the coal by crushing device percutaneously into the bunker through a the spreading coal coal injecting air into the furnace; circulating ash by heating, fluidized combustion process. When the coal into a gas fuel is injected directly into the combustor for combustion. 2. Combustion of Coal is mainly composed of C, H, O, N, S, ash and moisture and other elements. Generated when coal SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from flue gas emitted into the atmosphere, pollute the environment and cause harm to humans. The main components of the exhaust gas and coke are CO and H2. The main produce CO2 and H2 post-combustion, much lower than coal-fired boiler SO2, SO3 and NOX emissions. 3. Ventilation pressurized combustion coal combustion boiler used in a combustion mode. The bottom of the combustion process through the induced draft fan with fan and completed. In the combustion of coal, it requires a lot of air. Gas under a slight positive pressure in the boiler or burner slightly negative pressure, which requires less airflow. Burner air may be pre-mixed with natural gas. 4. coal boiler control reasons, material thickness, amount of wind, the wind volume, wind and other than coal, coal-fired boiler is difficult to automatically adjust the operating parameters of the boiler according to the load. However, fewer factors gas boiler, the burner valve can be adjusted according to the size of the load, easy to implement automatic control. Coal-fired boiler to a gas boiler Notes: Main results are as follows: (1) small boiler, the coal-fired boiler to a gas boiler, i.e. the negative pressure of combustion from the original to the current combustion slight positive pressure, and must pay attention to the furnace wall structure sealing problems. Closely related (2) selection and arrangement of the burner and furnace, the degree of filling of the flame in the furnace is preferably not formed dead air, to avoid the interference of adjacent flame burners, to avoid interference from adjacent burner flame. Unburned gas - air mixture should not be in contact with a heated surface, in order to avoid incomplete combustion. Gas combustion. Gas burner arrangement disposed conduit and ducts should be considered reasonable gas pipe and duct arrangement, ease of operation, inspection and maintenance. (3) the transformation of coal-fired boilers is mechanized layered gas boiler should be removed before the arch and the arch, and the bottom heating surface increases, in place of the grate, the grate to prevent overheating. Gas Velocity (4) on heat transfer surface of the fly ash is not restricted abrasion conditions, convection heating surface heat transfer coefficient is increased, increasing the pressure in the boiler where H is unduly increased. Boiler erosion surface. At this time, the capacity of the boiler should be noted that the steam separator to ensure the quality of the steam.
