Study On Improvement Of Boiler Combustion System

Before the80’s of the twentieth Century, the boiler design in our country are almost allcoal-fired boilers, fuel composition is mainly dominated by coal. Now, with the developmentof the times and the need of industrial, oil heating and pipeline heat tracing, including someboiler room heating equipment mainly rely on the central boiler system. Of course, in order tosave energy, strengthen environmental protection, coal fired boiler is basically no, now is thefuel oil or gas boiler, the development direction of the final should be gas boiler, in the nextfew years, natural gas as a clean energy source, will be popular in many regions of the country.This will bring a broad market for gas burner.The amount of fuel in a boiler, air quantity and air guide control tasks of the three cannot be separated, can use three controller to control the three control variables, but theyshould be coordinated, can work reliably. For a given water temperature, you need to adjustthe proportion of blast volume and to the gas, the boiler operation state in the best combustion.At the same time should make the memory in a certain negative pressure, in order to maintainthe boiler thermal efficiency, avoid the overheating outwards Spitfire, ensure the safety ofpersonnel and environmental health.In order to realize the amount of fuel, air flow and air input in coordination, burner, airsupply, fuel hole side installation of control valves, control is transferred to the chamber,temperature, pressure data to achieve automatic control in distribution box, and displayed onthe computer screen, the computer detected steam pressure (water temperature) parameterchange, combustion adjustment, and adjust and protection according to various kinds ofabnormal conditions caused by changes in gas pressure, and the realization of visual control,so as to achieve economic combustion, safety and protection purposes.
