The Secretary-General Wang Group to a variety of innovative measures gave high praise, the use of multimedia technology exhibition virtual and digital technology to explain the esoteric condensing boiler experts technology, not only new forms but also improve viewing and exploration interest, indeed boiler technology showcase of a major undertaking; clean fuel test Center is the real installation run a variety of products, set energy efficiency testing, the burner test, strengthen research experiment of heat transfer, centralized control system as a whole, provide a true and reliable test data support for a variety of indicators, to promote gas-fired boiler development of the industry plays an important role.
How to prevent running back pass secondary combustion 1, 30% of the rated condensing boiler experts 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.
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.
Burner is one of the important equipment a decision whether the normal operation of the boiler, burner now divided into oil burners, gas burners and dual fuel burners (also called dual-use oil and gas burner).Free Chat
