What is the state of a burning oil-gas boiler after it is put out? How to judge whether the burning oil and gas boiler is extinguished? Oil-gas boiler manufacturer-gas-fired Fangkuai boiler for you to introduce in detail: The indicator value of the negative pressure gauge in the furnace of oil and gas fired boiler suddenly increases, the furnace blackens, the flame can not be seen from the fire hole, the combustion sound in the furnace disappears, the flame monitor sends out the fire extinguishing signal. Air temperature, air pressure drops sharply, water level drops first and then rises, etc., all of which are extinguished. Due to the auxiliary engine accident caused by the quenching, such as induced fans, blower power interruption, there is also an accident signal; if the fuel supply interruption, the boiler fuel or gas pressure is reduced to zero.

The main reason gas steam boiler produces smoke which fuel gas steam boiler main cause of smoke. A fuel gas steam boiler: oil, gas oil quality is not good when the gas contains more water, reduce the heat value of the fuel, while producing steam, the furnace temperature tends to decrease, making it difficult to burn, easy to produce smoke. Water and more oil, mainly when unloading rain water into the oil during heating the oil in water vapor penetration. When the oil contains impurities, the impurities unburned produce fine coke, the coke into fine smoke, dust becomes large, and the formation of soot. Impurities contained in the oil and gas, but also affect the pure oil and pure combustion gas generated soot. Oil impurities, mainly due to inappropriate choice of filters or filter difference impurity removal effect. Second, the failure of the fuel atomizing nozzle member main burner fuel oil atomizing nozzle. Atomizing oil burner nozzle fails, affecting the quality of the atomization, easy to poor combustion. 1, the adhesiveness between the bonding surface of the oil and the consequences of failure oil atomizers swirl atomizers and the splitter plate well, leakage will occur, atomized large oil particles, increasing the amount of fuel injection and the like. In this case serious deterioration of the quality of the combustion, the oil droplets have landed on the water wall, stacking up oil coke, partially unburned black smoke into droplets. The tangential swirl chip groove clogging mist causes uneven density distribution in the dense side of the oil mist, combustion air be insufficient. In the more dilute side of the oil mist, combustion air causes severe local excess. Mixed with oil, wind conditions deteriorated significantly, combustion conditions deteriorate, resulting in black smoke. 2, spray atomization slice failure and the consequences of failure to clogging and wear. Nozzle clogging, resulting in blockage of the fuel injection quantity is not glib increase, oil particle size thicker, the effect of fuel poor and black smoke. Wear injection port, a large hole diameter, increasing the amount of fuel injection, increasing the particle size of oil affect combustion efficiency, produce black smoke. The use of artificial gas burner, naphthalene and tar and other impurities will block the nozzles, the influence of gas distribution, resulting in black smoke. Should therefore be cleaned regularly, or clogging of the selected burner. 3, the partition partitioning poor poor, insufficient supply of air into and excess. The amount of air can not meet the requirements of the fuel combustion, so that combustion of fuel can not be sufficiently black smoke. The amount of air, will result in lower combustion temperature, black smoke and fuel difficult to burn. 4, the furnace temperature is too low when starting the furnace, fuel oil steam boiler furnace temperature is too low due to easy black smoke. 5, the furnace hearth product oil is sometimes caused by internal combustion nozzle oil accumulated inside the chamber, the oil reservoir coke black smoke at high temperature. Causes dripping of fuel combustion nozzle: ① The drip just work, just at the operating pressure is too low, the oil will flow from the nozzle, instead of the discharge. The reason for low oil pressure is a solenoid valve, the valve is clogged filter or the like or failure caused by contamination. ② In the dripping process work, probably because the relative position of burner nozzle mounting head too far, improper ignition electrode position, the oil into the atomizer, the nozzle holder is mounted is not tight, nozzle dirty, low oil pressure caused. ③ When the dripping stopped, because the line between the pump and the air nozzle, electromagnetic valve or a hydraulic valve or dirty failure. 6, the furnace flue purged countless consequences when the furnace flue remnants of oil and gas, when gas purging endless, high temperatures encountered in the explosion and black smoke. 7, the furnace smoke, sparks, the furnace pressure is too ①; ② inappropriate choice of the burner, the burner flame is too long or too much power; ③ improper combustion ratio, there are more to produce products of incomplete combustion; ④ atomization quality is not good nozzle or improper installation location, or affect the combustion flame into the furnace off port; ⑤ flue is blocked, poor smoke; ⑥ a secondary air mismatches; irrational ⑦ furnace structure; ⑧ oil spray angle is selected from with improper.

Boiler "coal to gas" to give users what the vital interests: As one of the participants "coal to gas" project, fast boiler with a high-quality, high-tech, intelligent features, efforts to respond to China's "coal to gas "call to actively push green energy power production equipment, make the sky bluer, the clear water and greener!

Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam boiler can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).
