50, when arranged inside the boiler room to note a safety distance, the front end of the boiler ready spacing of not less than 2/3 of the length of the furnace, and not less than 2 m; vertical boiler can be shortened; bulk boiler is not less than 4 m and does not affect the blast furnace operation and maintenance. 2, the boiler side and rear channel spacing of not less than 0.8 m, and should meet the operational and maintenance (such as replacement tube bundle cleaning, stirring the fire, etc.) requirements. 3, the top horizontal boiler headroom not less than 2 m; vertical boiler top clearance height to facilitate the operation and maintenance; headroom boiler room the other channels, should not be less than 2 meters, when the passage of time and no need to operate its headroom height of 0.7 meters. 4, the boiler room is provided for two or more boilers, the boiler the distance between adjacent not less than 1 to 1.5 times the cylinder diameter of the boiler. 5, the boiler room is generally preferred fireman operation chamber provided, on the total rated greater than or equal evaporation 4t / h professional shenghua new steam boiler for retort (heating or hot water boiler is equal to or greater than 2.8MW) must be provided stoker operating room. Electric boiler tank may be provided in front of the boiler, and to ensure the art to fireman facing boiler water gauge, pressure gauge and other instruments during operation. 6, to the total rated evaporation 2t / h fuel gas boiler room to be provided or water spray foam fire extinguisher system, should outdoor outdoor fire hydrant, other fire-fighting equipment should also have the boiler room. 7, the fuel in the boiler room daily oil tank, the oil pump is generally not located in the boiler room, between daily oil tank, the oil pump between the application of the fire resistance of greater than 2.00h wall, the fire resistance of greater than 1.50h floor spaced from the other parts. Daily fuel tank between the boiler room and the door between the oil pump should be able to self-closing fire doors Class A, and let the oil block measures. Household upper tank return pipe to be provided, should be greater than the oil return pipe back to the oil pump. 8, an oil tank and all piping must have a reliable electrostatic grounding, the grounding resistance should not exceed 30 ohms. 9, gas boiler room boiler design should also comply with the relevant safety requirements of gas boiler room.

The main reason gas professional shenghua new steam boiler for retort 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.
