How to prevent running back pass secondary combustion 1, 30% of the rated boiler suppliers exporters 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.
The price of szs boiler suppliers exporterss is generally lower than the wns type. We will provide oil and gas boiler quotations according to customer needs. The more detailed the information provided by the customer about the demand, the more detailed the boiler scheme we give, and the clearer the price. The price list we provide includes the price of the boiler body and different auxiliary parts.
WNS Gas and Oil Dual Fuel Horizontal Boiler
It is the fire tube dual fuel boiler; the boiler is a sub-project of world band GEF high efficient & environmental boiler project. Cooperated with Germany technology, the horizontal gas & oil fired boiler main technologies have reached the advanced world level. The dual fuel boiler adopts three-pass, wet-back structure, large combustion chamber makes the burning fully. Imported burners such as Weishaupt, Baltur, Riello, etc are equipped to ensure a high combustion efficiency.
Comfortable life of people is inseparable from the northern winter heating boiler suppliers exporters, normal, stable heat source is vital to people's lives. But the attendant is an increasingly serious environmental pollution problems, the implementation of coal to gas policy without delay, using the gas hot water boiler is the general trend. In order to achieve green heating, the National Tourism Administration Service Center decided to phase out the existing coal-fired boilers, the introduction of clean and environmentally friendly gas hot water boiler. Fast boiler with their own strong comprehensive strength and rich experience in the heating industry cooperation gained the trust of the National Tourism Administration Service Center, and ultimately provide a vacuum hot water boiler (T6-2800 2 sets of 2.8MW by fast Boiler ).
