Low nitrogen boiler revolution to lead the industry in fact so much importance to the APEC summit in nitrogen oxide emissions from the boiler is not accidental. Nitrogen oxide emissions into the atmosphere dissolved in water will generate nitric acid rain, caused extensive harm to the environment, causing huge losses to the economy. For the boiler, fuel combustion is the main part of the nitrogen oxides generated. However, in most cities, nitrogen oxide emissions from the boiler still remain at a high level, or simply just to reach deeper coal to gas demand, low nitrogen, low dust and other environmental requirements far not on the agenda.
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.
Coal fired boiler design features:
1.By adopting of double wings gas ducts, the fuel gas can go into the front gas tank easily, so the temperature of different front plates can be same. In this way, it can avoid the crackles happening in the plates.
2.Spiral tubes are installed in the drums, which can strengthen the heating transferring efficiency, at the same time, spiral tubes have the ability of dust removal, which can avoid the dust stratification in the tubes.
3.Both of the front and the back arches of the 10t/h series coal fired boiler design adopt mason work of water cool tubes wall structure, which can form permanent arches.
4.Separate adjustable wind chambers. Wind is feed from two sides. It adopts new type crank screw wind adjustment structure, so that the wind adjustment and ventilation cross section proportion is 100%, which can ensure the easy wind adjustment and make it symmetrically.
5.There is push-pull damper dust removal equipment. The damper adopt finish machining cast iron seal structure, thus the secondary combustion distortion and air leaking in the grate is effectively prevented.
Horizontal 0.5 tons supervisory inspection-free amount of gas china dzl type coal fired steam boiler is how much? There are a lot of users call and ask when will the relationship between the amount of gas steam boilers are, of course, this problem is related to the user's operating costs, and all of us today about 0.5 tons of horizontal gas-free amount is how much steam boiler inspection supervisor . First to introduce my company developed its own supervisory inspection-free steam boiler, only about 110 degrees this steam boiler exhaust gas temperature, and ordinary steam boiler exhaust gas temperature as high as 250-350, saves considerable steam boiler if the index is to see its exhaust gas temperature, exhaust gas temperature is lower fuel burn more fully explained in the furnace, the more fuel is absorbed by the heat from the steam boiler, the more fuel-efficient, the company supervisory inspection-free horizontal 0.5 tons of steam per hour coal boiler is about 40-50 kg, Common horizontal 0.5 tons coal consumption is about 70-80 kg.
