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 industry steam boilers brands (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.
Since our company uses WNS6-1.25-YQ split two condensing boiler, the boiler runs very stable, high degree of automation, greatly reducing the labor intensity of fireman our staff, because running very clean without any emissions, but also greatly improved our paper mill house and the surrounding environment, high operating efficiency boilers. Service is also very timely response to our technical consulting reply quickly and accurately. Especially for regular visits to thank! --customer feedback
Boiler fire phenomenon, how to do 1, furnace pressure fluctuations or to limit and alarm. 2, no flame detector flame, flame flameless television display. 3, flue gas oxygen abnormal fluctuations. 4, steam pressure steam temperature dropped drastically. 5, furnace black, black smoke chimney. 6, the flue gas temperature is reduced. 7, MFT action, turbine trip, splitting the unit. Cause 1, the furnace combustion conditions organizations unreasonable, improper wind coal proportion. 2, the load is too low, unstable combustion conditions without oil combustion vote, or vote, although oil but not good combustion results. 3, cast oil, poor quality oil, oil spray gun is bad, low oil pressure, oil system failure. 4, poor coal quality, coal is too rough, the water is too large pulverized coal combustion adjustment is not timely. 5, the primary air temperature, air pressure is too low. 6, boiler MFT protection action. 7, a large area of the furnace coke collapse, smashing off the flame. 8, severe water wall pipe explosion will blow out the flame. 9, all coal-fired condition, mill pulverizing system failure caused most or all trips. 10, a part of auxiliary machinery such as a fan, blower, fan, air preheater tripped, causing unstable furnace combustion conditions. 11, sootblowing properly, resulting in a large number of normal operation of the furnace ash effects of fire inspection of the boiler. 12, bottom seal damage. Treatment 1, the boiler fire, MFT should be action, otherwise manual MFT. 2, normal inspection device linkage linkage MFT, confirm that all fuel cut. 3. quickly identify the cause, try to eliminate the boiler can be re-ignition, the recovery unit operation. 4, when the mill started again after the trip, the trip must be the primary air tube mill full purge. 5, the MFT operation, checks, Fan normal operation, automatic furnace vent. 6, the MFT movement, check all the secondary purge air damper position is set, the total air volume is automatically adjusted to 30 ~ 40% BMCR sufficiently purged air volume. 7, the MFT operation, when the turbine is in a state disk drive, the disk drive must continue until the normal turbine eccentricity, before re turn red. 8, if temporarily unable to identify or eliminate the cause, restart and could threaten personal safety equipment, non-start. 9, processing according to the corresponding predetermined remaining MFT.
Advanced equipment and principles of industry steam boilers brands desulfurization and dedusting analysis of small and medium boiler outlet dust concentration in the combustion of various structures are much higher than the maximum allowable dust concentration values specified in our standard, so in addition to the correct choice burning structure and improve operational level, to burn coal dust boiler equipment must also be provided at the rear of the boiler, the flue dust is then trapped into the atmosphere. Dust into five categories according to their action principle (1) comprises a gravity dust precipitator mechanical force, an inertia dust collector, a centrifugal dust collector. (2) comprises a water bath washed filter dust collector, a foam-type dust collector, venturi dust, water, dust and the like membrane. (3) comprises a filtering dust collector (4) an electrostatic precipitator and baghouse dust particle layer and the like. (5) a magnetic filter. Gravity settling dust collector 1. The principle is: When the flow rate of the flue gas into a large space to reduce soot particles by means of its own gravity larger, natural settling by gravity separated from the flue gas. 2. The cyclone dust cyclone called centrifugation, the principle is strongly flue dust along the cylindrical wall is rotated within the gas cyclone, and gradually decreased along the tubular wall a helical motion. Strong centrifugal force generated by rotation, the cylindrical wall surface of the body thrown dust, dust on the wall surface by gravity to the bottom of precipitator gradually decreased, and is discharged through hoppers. Purified flue gas is discharged from the middle of the dust core tube. Centrifugal mill precipitator 3. The principle is: the tangential direction into the flue gas at a high speed from the lower portion of the cylindrical housing, along the rotating cylindrical wall, the nozzle along the upper circumference of the cylindrical housing into a uniform tangential spray in when the inner wall of the cartridge housing forming a water film, since the centrifugal force, is thrown dust cylindrical wall, and the stick water film and water film flows along the conical hopper, is discharged from the ash discharge outlet, the purified flue gas from the housing an upper discharge.Free Chat
