wns series oil or gas fire tube steam boiler

Steam boiler steam separator device works in the overall design of the wns series oil or fire tube steam boiler, steam separator device is essential, rapid separation of water saturated steam is to improve the steam quality to ensure that an important part of the normal operation of the boiler. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Convenient to meet customer needs. Then, the authors will guide you to understand the working principles of steam and water separation device on the steam boiler. First, to avoid increasing the local load between the evaporation surface and the vapor space drum boiler, the steam is uniformly by water extraction. Second, it can effectively weaken the kinetic energy soda mixture into the tank, reducing its impact on the water. Third, in order to take advantage of inertia, and centrifugal separation, the mixture having a flow path soda rapidly changing, keeping in mind the shunt separation of water, to avoid being carried steam again. Finally, there is a large surface area, in order to adhere more water droplets. At the moment, a lot of steam separator type, according to the principle of the separation can be divided into natural and mechanical separation. The principle is to use natural separation of steam and water and the density difference between the force of gravity. Mechanical separation principle relies on inertial force, centrifugal force and adhesion. Water separation apparatus is often installed in a steam boiler and used underwater plate, baffle, plate uniformity, manifold, volute separator, corrugated sheet and steel mesh separators.

Boiler water treatment analysis of safety issues: the problem of boiler water treatment is an important part of the process of the safe use of boilers in general we all know that the market is now using more coal-fired wns series oil or fire tube steam boiler, steam boiler fuel ratio or gas accounts for a large steam boiler most, especially in the current market share of imports of fuel gas-fired boiler in the market constantly rising, mainly due to fuel gas-fired boiler of compact, small size, high water quality requirements, at the same time, due to the oil and gas combustion temperature itself relatively high, therefore, be able to do is very important for boiler water treatment, boiler water treatment, if done well it will cause boiler fouling, corrosion, which not only wastes fuel and it can lead to blocked pipes, burst pipes and other accidents, and more there will also be scrapped boiler caused severe economic losses ***. Therefore, fuel oil and natural gas boilers must strictly check boiler water treatment problem seriously.

Gas boiler safe operating procedures: gas-fired boilers this kitchen I believe we are not unfamiliar fishes it. But this thing is not so easy, and sometimes improper operation causing very serious consequences, so the gas boiler rules is very important. That in the end this is how the specific operation of it, if you want to know, quickly told us with a look. 1. All personnel must be familiar with the operation of the boiler performance and safety knowledge of the boiler operating certificates. This post is strictly prohibited non-operating personnel. Duty should be strictly in accordance with the operating records and do a good job shift recording, the security situation and the device should shift change operation tests, carried out. When the shift to check the boiler is intact. 2. Boilers and safety accessories should be inspected, and in the period. 3. Kai blast furnace gas furnace ready ① Check if the gas pressure is normal, not too high or too low, open the door of oil and gas supply section; ② Check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Open the Water Supply System for each section of the door (front door section Sheung including pumps and boilers); ③ check level gauge, the water level should be in the normal position, the water level gauge, a water level required color plug in the open position, the water level to prevent false, if water can be manually Sheung; ④ check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob ⑤ checks the control cabinet are in their normal position; ⑥ wns series oil or fire tube steam boiler check valve should be in the closed state hot water boiler circulating pump outlet valve should be turned off; ⑦ checking water softening equipment is operating properly, a variety of indicators to create a soft water meets national standards. Open the power ⑴; ⑵ startup burner; ⑶ purge valve on the drum, is completely out of steam, the off; ⑷ inspection hole into the boiler, and the hand hole flange valves, the leak was found to be fastened, tight as the solid leakage maintenance shutdown; ⑸ pressure rise when 0.05 ~ 0.1MPA, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; ⑹ when the pressure was raised to 0.1 ~ 0.15MPA, flushing pressure gauge trap; ⑺ when the pressure was raised to 0.3MPA, "fire load / small fire" knob to "fire" to strengthen the combustion; ⑻ when the pressure was raised to 2/3 of the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; ⑼ drain valve is completely closed out of steam; ⑽ after all the drain valve closed, slowly open the main valve to open, and then half a turn; ⑾ "burner control" knob to " Auto "; ⑿ level adjustment: adjusting the water level (to manually start and stop the pump) according to a load, low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; ⒀ steam pressure adjustment: adjusted according to a load combustion (manual adjustment Fire / small fire) ⒁ combustion state determination, determines the amount of fuel atomization air ⒂ observation condition exhaust gas temperature, smoke, temperature control is generally between 220--250 ℃ The flame color, smoke color, while observing the chimney exhaust gas temperature , concentration, adjusted to the optimum combustion state. ⑴ Open the power; ⑵ start the circulation pump; ⑶ slow circulation pump outlet valve; ⑷ startup burner; ⑸15 min "" Load fire / small fire "bit color button is turned to" fire "" ⑹ "burner control" knob spin to "automatic." 5A normal shutdown: hot water boiler ① "fire load / small fire" knob to "small fire"; ② off the burner; ③ close the fuel supply valve; ④ ⑤ closing dampers boiler after the temperature dropped to 50 ℃ , the circulation pump outlet valve closed. ⑥ stop circulation pump

Second Session of the CPPCC National Committee Session of March 5 press conference held in the afternoon, the CPPCC National Committee of Population, Resources and Environment Committee, Democratic National Construction Association Central Committee, Environmental Management Division of the Ministry of Ecology Environment Atmospheric Liu Bingjiang said: Last year, resolve more than 30 million tons of steel production capacity, 810 million kilowatts of coal-fired units basically reached the national emission levels of natural gas, built the world's largest clean coal power base, out of 1.3 million units in industrial furnaces, coal accounts for the country's primary energy consumption the proportion of first time below the 60% to 59%, and turned off the small coal-fired boilers 23000 units.

At present the country has completed a preliminary air pollution control goals, the future will continue to promote coal-fired boilers governance, and the introduction of more stringent emission performance standards of air pollution.
