Petcoke is not just a refinery’s by-product any more, but a real alternative cost effective fuel that can be successfully fired in CFB distributor boiler machine 20 tons either alone or in blends with coal.
First, before running a check, check whether the flow line, the valve 2 is open, the distributor boiler machine 20 ton can not be installed on any air opening the valve, through the atmosphere. (Such as boiler pressure should be checked whether there are significant changes in the pipeline clogging) 3, expansion tank and through a large pipe freezing measures should be noted, not frozen. 4, the use of the heating season a year ago, need to check, clean water in the heating system, impurities.
Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of 38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original distributor boiler machine 20 ton equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
The key to avoiding the excess air in the furnace is the proper air distribution and the appropriate monitoring and control means. The monitoring method has a method for measuring the content of CO2 or O2, and the oxygen content of the gas distributor boiler machine 20 ton is usually determined. This is because the gas boiler is burned with a slight positive pressure, and the sealing problem is easily solved. The measurement of the oxygen content accurately reflects the excess air coefficient value. Nowadays, the oxygen content measurement technology generally uses a zirconia constant temperature oxygen analyzer to continuously measure the oxygen content of the flue gas. According to the oxygen content of the flue gas as a reference, the air-fuel ratio is properly adjusted to perform low-oxygen combustion.
