How fuel (gas) 20t boiler dealer belarus stack height standards should be implemented as specified?According to requirements "Boiler Air Pollutants Emission Standard" -GB13271-2014 existing files countries, oil, gas boiler chimney of not less than 8 meters, the height of the boiler chimney by specific approval of environmental impact assessment documents OK. When there is a building within a radius of 200m from the new boiler room around the chimney, the chimney should be higher than the tallest building in more than 3m.
How to prevent running back pass secondary combustion 1, 30% of the rated 20t boiler dealer belarus to deal with the amount of purge air before boiler ignition; the boiler must be 30% of rated air flow purge less than 5 minutes after the boiler fire, or allowed to boiler re-ignition. 2, fine-tuning the boiler and combustion systems pulverizing system operating conditions, to prevent incomplete combustion of oil and coal accumulating on the tail heating surface or flue. 3, boiler burning oil, adjust the proper air flow, fuel flow, confirming good gun oil spray, burning completely. If you find a bad oil spray gun should be discontinued immediately, and clean up. 4, when the oil application group administered powder, cast powder should be confirmed before the oil burner ignition good, or allowed to cast powder. 5, the oil powder boiler during cofiring, and check the fuel oil gun system of fire reinforcement. 6, normal operation, operation personnel in monitoring the economizer, an air preheater flue tobacco in different conditions of temperature, abnormal, should be checked to detect a fire-place. 7, air preheater sootblowing steam system normally put into operation, the soot-blowing pressure and temperature in a predetermined range. When the unit load or less prolonged 300MW kerosene mixed combustion, air preheater sootblowing steam to be continuous. 8, the air preheater into a reliable fire alarm device. 9, an air preheater inlet and outlet fume / air damper, and should be able to put an electric shutter can be open, closed tight. 10, if found preheater stall, should be put into operation again immediately, if not turn back, they should be isolated.
Prevent explosion of the furnace, the fuel (gas) 20t boiler dealer belarus flame protection means must be provided, is a function of combustion (including ignition, combustion or misfires when halfway off, typically within five seconds re-ignition furnace in the monitoring, within 1 second running off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds purge, automatically cut off the blower and various auxiliary power boiler stop running.) by the flame monitoring and control device component. Role is to monitor the flame control device signals the presence of a flame or interrupted.
Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, 20t boiler dealer belarus flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
