coal fired double drums water tube steam boiler

coal fired double drums water tube steam boiler

After the gas hot water boiler hot water boiler vaporization emergency 1. Vaporization handler circulating pump stops abnormally pump failure caused by: ① blower stops running immediately. ② immediately open the door, take measures to pressure the fire, lift the chute gate, cutting off the supply of coal grate. ③ In the case of boiler pressure not greater than 0.6MPa (600KPa), the exhaust valve to follow, only a sharp rise in pressure in the boiler deflated, used only relief exceeds 0.9MPa, and the exhaust process to be carried out slowly, prevention boiler due to loss of pressure and more violently again vaporized. ④ close the boiler water, water main gas valve. ⑤ open stop valve recirculation line, to ensure that the water supply pipe velocity convection heating surface (economizer) to prevent re-vaporization of the economizer. ⑥ The operation of the above operation, at the same time to pay the boiler to reduce the boiler water temperature and the furnace pressure. ⑦ After the boiler pressure is normal, i.e., opening the standby circulating pump, into the normal combustion. 2. Treatment failure or sudden loss of power boiler vaporization of power: ① immediately open the door, lift the coal chute slide gate to take pressure fire measures to reduce the oven temperature. ② Grate with the fastest speed in order in the shortest time to fire onto the slag tap. ③ the degree of treatment in the first case. Once a short time can not supply heating network system, antifreeze should take emergency measures. 3. Due to excessive heat boiler boiler vaporization process: ① the immediate closure of the drum, induced draft fan. ② immediately open the door, take measures to pressure the fire, lift the supply of coal chute slide gate, off of coal, while the grate into fast gear. ③ In the case confirmed the presence of water, the boiler can supply water to the boiler body, boiler out of the water while closing the main valve. ④ Open line stop valve recirculation pump to ensure water velocity convection heating surface of the pipe, to prevent the economizer again vaporized. ⑤ Open circulating pump with jog mode, jog each time less than 30 seconds, again less than one minute jog interval. Jog purpose is to reduce the boiler water temperature, while preventing a large amount of steam into the pipeline system. ⑥ back into place after the safety valve, circulating pump running, and then the normal burning stove. 4. Water boiler system run vaporization process due to water loss, loss of pressure caused by: ① immediately closed drum, induced draft fan. ② out of the water while closing the main valve and the boiler circulating pump. ③ take the same measures to cool the furnace tube described above. ④ Open stop valve recirculation line. ⑤ rely exhaust valve until the safety valve back into place. ⑥ until the boiler water temperature drops below 50 ℃, when the temperature of the furnace temperature less number 200 ℃, again within the boiler feed water, water course to be carried out slowly, to prevent harm to the boiler when the temperature is too large. ⑦ After processing leakage fault, the system time to the replenishment, and out of the water boiler always open the valve, and the circulating pump, and then normal combustion.

6 tons gas coal fired double drums water tube steam boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.

Electric heating coal fired double drums water tube steam boiler to bring clean air to generate electric heating steam boiler for your life can be said to greatly improve the problem of environmental pollution and energy saving issues, while electric heating steam boiler changed the traditional old-fashioned coal-fired boiler volume great ills, developed the electric heating steam boiler is very small, beautiful, energy-saving and environmental protection is on the leader. The traditional coal-fired boilers serious waste of energy coal This one-time, while there are still major problems of environmental pollution, the gradual strengthening of national environmental awareness of today no longer adapt to market development, which also makes the development of electric heating steam boiler. Enjoy our life is not just well-off life, as well as the air is clean. Electric heating steam boiler products can bring clean air to your life. Electric heating steam boilers in coal-fired boilers than just on the price a little high, but in the long run (environmental protection and energy efficiency) electric boiler products are very affordable, we should not give up on him a little bit expensive, so may be set would be wasted.

Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
