dzl series gas fired hot water boiler price
Gas-fired steam boiler which in modern industrial production, although the boiler very prominent role played by the choice of cleaning agent, but it is also very easy to scale boiler is subject to corrosion or damage. Gas boiler steam heater in such a situation therefore requires timely associated boiler equipment for cleaning, and performance of the practical utility of the most prominent non-gas-steam cleaners which is none other than this. Where a new gas heating system to replace the steam pipe cleaning agent must be used to eliminate the inner wall of debris so as not to affect gas-steam heat transfer efficiency and service life. It should be carefully checked, in use, to prevent water, acid, alkali and leakage into the low boilers using the system, and to install the filtration device, to prevent mechanical debris into the system to ensure the purity of the oil. A gas-steam with hot brands and process requirements, the correct selection of various grades of high-temperature gas-steam, and strictly abide by the provisions of the "organic heat carrier furnace Safety Technology Supervision" in the proper use of gas steam. Gas steam boiler at a high temperature gas for gas steam, gas, fuel furnace as a carrier, electric heating reactor and other heating devices, shall have the expansion tank and the oil sump and other security components and temperature control instruments and other facilities, to ensure safe operation. Purpose cleaners gas steam boiler is effectively rapid clearance gas steam boiler and the heat exchanger internal conduit accumulated soot and grease. Then we also have requirements on the cleaning agent, must not harm our metal heat transfer surface, requiring no residue, is completely dissolved, it must be easy to operate and requires only the use of the process in accordance with the needs of ordinary people to operate. Requires us on the gas boiler steam oven cleaners are: low energy environment, Wudu tasteless, non-flammable, irritation, can be directly discharged after cleaning.
Henan miss you Jujube Industry Development Co., Ltd. is mainly engaged in dates, nuts and other healthy food research and development, procurement, production and sales operations; jujube industry's first listed company. I miss you date industry is committed to providing health and hygiene products for people to date, in 2017, I miss you date industry decided to buy a few new clean and green, can provide high-quality steam boiler steam. Carefully selected is determined in cooperation with the fast boiler, signed two separate 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
Tail secondary combustion flue how to deal with the phenomenon of a sharp increase in rear of the boiler flue secondary combustion flue temperature location and later. 2, the furnace, the flue abrupt change in negative pressure, flue gas is not tight at the smoke, the Mars. 3, air preheater large current swing bearing housing temperature, severe Jam occurs. 4, air preheater fire alarm issue. 5, steam temperature, economizer outlet water temperature, the air temperature rises abnormally. 6, induced draft fan vanes automatically open a large, Fan current rise. 7, as the combustion side, both sides of the smoke temperature difference increases. Reason 1, through the coarse fine grinding coal, coal poor uniformity, improper adjustment of combustion, combustion of fuel is insufficient, serious mechanical incomplete combustion, and high levels of combustible ash accumulated in the back pass. 2, an oil burner or an oil poor atomization, so that unburned droplets deposited in the flue. 3, prolonged low load operation of boiler, the furnace temperature is too low or too small amount of excess air resulting in incomplete combustion of coal or oil accumulated in the tail. 4, after the shutdown of the fuel leakage into the furnace and accumulates or after shutdown and to insufficient MFT furnace purge unburnt coal or oil accumulation at the end of the tail. 5, soot blower failure, long-term put into operation is not normal. 1 process, when a slight secondary combustion, exhaust gas temperature does not rise within 20 ℃ normal smoking temperature should be checked immediately paragraphs, the combustion site and judge whether the secondary steam soot blowing. (When the exhaust gas temperature rises to 250 ℃) 2, the operation of the back pass and then generating boiler combustion boiler operation should be stopped immediately, immediately stop sending, ID fan and turn off all the smoke and steam soot blowing air damper fire. 3, if the economizer afterburning, until the storage tank level control valve blocking off without pressure, flow rate of feed pump motor start 150t / h Sheung be cooled. 4, air preheater heating surface of the secondary combustion air preheater normal operation, normal operation of the air pre-heater holder; air preheater Jam occurs, the main drive motor and the auxiliary drive motor trip, contact maintenance manual plate moving continuous air preheater rotor. Soot blowing steam into air preheater for extinguishing, into the air preheater for fire extinguishing can not be extinguished. 5, the economizer outlet water temperature close to the inlet temperature (at the economizer secondary combustion), the air preheater inlet gas temperature, exhaust gas temperature, the hot air temperature is lowered to less 80 ℃, each one hole, and the hole is no longer Mars smoke and soot blowing steam stops coming out after water or fire. Open hole inspection manhole and inspection to confirm the secondary combustion goes out, after the flue vent door open to drain water inside the smoke flue opening for ventilation air damper. 6, to be re-combustion is resolved, the flue temperature does not rise and fall when stabilized, before slow regulation of the air, smoke baffle, the necessary air cooling and purging.
You must know the problems of energy consumption boiler (boiler thermal efficiency) 1, because the thermal efficiency of boiler problems of a high exhaust gas temperature. b sootblowers into low. c ash combustible large. d is too large or too small boiler oxygen. e heat loss is large. f large air preheater air leakage rate. g coarse pulverized coal. h steam - water quality is poor. I defective equipment, operating parameters are forced down. 2, measures to solve the problem of a lower exhaust gas temperature. b timely elimination of soot blowers defects and improve the investment rate of soot blowers. c reduce fuel ash, slag combustibles. d control the amount of oxygen in the boiler. e reduce heat loss. f air preheater to reduce air leakage rate. g qualified coal fineness control. h to improve the quality of soft drinks. i According to circumstances, the boiler heating surface adjustment arrangement. J burner when necessary transformation to fit the gaseous fuel.
