How to solve the noise problem electric papermaking hot water fire tube boiler for in life, noise pollution is more serious, say, watching TV sound on too high, affecting the rest of the neighbors; the dead of night, when suddenly a loud whistle and so on, as long as influence people to rest, study and work in sound, we call it noise. With the development of modern industry, environmental pollution along with produce, noise pollution is a kind of environmental pollution has become a hazard to humans. Noise and water pollution, air pollution, solid waste pollution is seen as four major environmental problems worldwide. In real life boiler is a very common industrial equipment, boilers and our daily lives. But a lot of work ordinary boilers because of the existence of objective factors that led to the smoke generated noise and emissions out of the life and health of the residents have had a great negative impact, there are many residents because of disturbing behavior boiler plant boiler plant to court . These phenomena we have to raise the importance of environmental protection function of the boiler. First of all, we should understand the harm of noise on the human body much, high-decibel noise will make people feel irritable, headaches, serious cause endocrine disorders, and even lead to insanity. So to eliminate the noise pollution caused by the boiler, the boiler fan noise processing technology is particularly important. When the boiler operation very noisy, more than people can afford decibels, but the temperature of the boiler flue gas generated very high, if the closed method will cause noise so that the device can not burn the heat inside the boiler important equipment. Therefore, noise reduction processing and energy of the boiler should be combined, as follows: The crossing of the induced draft fan and the blower into the inside the soundproof chamber, and then use them to ventilation ducts connecting the body and the boiler, the soundproof chamber walls and roofs carved small holes, while the mounting portion muffling apparatus. Control indoor blower silencer should be inclined to the direction of the boiler room, the air inlet is in this case windward position, to a greater heat production in the middle of the motor cooling channel. In this way the boiler during operation, the outside air can enter a soundproof room for replacement of the heat of the motor through the induced draft fan, and then keep the motor temperature is not too high. At the same time, soundproofed rooms and muffler noise reduction equipment also played a role, excess heat can also be recycled, reaching both energy saving and environmental protection effect. As long as the boiler solve the noise problem, then the boiler will have a good development trend, environmental protection boiler will get everyone's favorite.

You must know the problems of energy consumption papermaking hot water fire tube boiler for (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.

Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green papermaking hot water fire tube boiler for heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.

Tail secondary combustion flue how to deal with the phenomenon of a sharp increase in rear of the papermaking hot water fire tube boiler for 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.
