Boiler Association party leaders to come soon Group: innovation and development has won high praise, Secretary General of China Association for fuel consumption of one ton boiler water treatment boiler and arrogance Ling Wang, Assistant Secretary Guo Hua, chief engineer Tongyou Wu and his party three people come fast Boiler Group inspections visits, Luhai Gang president accompanied by full enthusiasm.
Boiler design efficiency in the engineer design phase, and in general, the actual operation and the initial design thermal efficiency are similar. For example, oil and gas furnace efficiency is greater than 92%, and circulating fluidized bed boiler efficiency is usually higher than 88%. However, boiler efficiency is not fixed. If your equipment is operating at less than design efficiency, then measures can be taken to improve boiler thermal efficiency.
How to determine whether the fuel gas fuel consumption of one ton boiler off state? Gas boiler furnace fuel indication value of the negative pressure suddenly increases; the furnace black, can not see the flame hole to see the fire; sound disappears combustion furnace; fire fighting monitor emits a signal; sharp decline in temperature, pressure, level decreased and then increased after so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply is interrupted as a result, pressure oil or gas boiler is reduced to zero.
How to prevent running back pass secondary combustion 1, 30% of the rated fuel consumption of one ton 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.Free Chat
