| Be used for ignition, stable combustion and combustion-supporting in power station boiler, biomass gasification technology has a positive effect on oil-saving in power station boiler and advance of biomass gasification application technology. With the utilization of biomass gasification technology, we preliminary research and develop a kind of system and equipment which is suitable for ignition and combustion supporting of power station boiler. Based of reading lots of references, biomass gasification technology is discussed in detail in this thesis, including the basic principle, process, character of biomass gasification, and categories, working principle, character of biomass gasification equipment. The bio-gas ignition and combustion supporting system is general planed, and its gasification equipment is designed. The way of combustion of boiler igniter in system is compulsory premixed blowing, and the boiler igniter is designed with correlation theories. |
