heavy fuel oil boiler
How to prevent running back pass secondary combustion 1, 30% of the rated heavy fuel boiler 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.
Natural gas and oil are widely used in different countries and regions, and various natural gas pipelines are densely packed and convenient to purchase. For oil and gas heavy fuel boilers, the use of natural gas, petroleum and other fuels can be piped, which saves on site and labor costs. Moreover, natural gas fuel is a clean energy source that can reduce sulfur dioxide and dust emissions, reduce carbon dioxide emissions and nitrogen oxides emissions, help reduce acid rain formation, soothe the global warming effect, and improve environmental quality.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water heavy fuel boiler to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
Up to now, large and small heavy fuel boiler manufacturers at home and abroad do not know how many, various types of boilers are also constantly developed. The boilers produced by ZG boiler have oil and gas boilers, biomass boilers, waste heat boilers, circulating fluidized bed boilers, chain grate boilers, power station boilers, etc., which are sold worldwide.
