oil for oil boiler machine

Classification is the use of fuel oil-fired for boiler machine and practical, this boiler is the boiler variety of diesel fuel and waste oil, his overall construction and arrangement of the gas boiler is similar to a common classification of mechanical and steam materialized style.

Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of for boiler machine welds is more guaranteed.

With the reduction of non-renewable resources, higher cost of energy and environmental protection, new type and eco-friendly for boiler machine is needed urgently. Winter is Coming, and it will be colder in the Northern Hemisphere. Thus, we need heating boiler badly. ZG Boiler’s new development natural gas fired boiler for central heating are hot sales now. This new designs boiler is more energy-saving and eco-friendly than others. Trend boiler market growth to gradually shift the high thermal efficiency, environmental protection, energy-saving features. New environmentally friendly boiler enter the market and is widely recognized. Total biomass boiler worldwide to 18.6 million units, and existing conventional gas, oil, coal, electricity, solar boilers will fully update replaces. With adjustment of energy structure, low-power boiler market share significantly increased its impressive growth rate, output growth has accounted for second in the world. The growth of Chinese boiler manufacturing industry needs updating and innovation.

How to prevent running back pass secondary combustion 1, 30% of the rated for boiler machine 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.
