Abstract

The present invention relates to a burner for a boiler using solid fuel such as wood pellets or the like, which are in the spotlight as biomass energy, and realizes a new combustion type, wherein fuel is transported using a screw circulating water inside and burnt in a predetermined section supplied with air (oxygen) by a blower. Therefore, it is possible to secure the durability of the screw even at the high temperature generated during the combustion, and complete simultaneous treatment of sludge and ashes. In addition, it is possible to largely reduce the size of the boiler using solid fuels, thereby simplifying the entire structure of the boiler, while promoting the reduction of manufacturing cost.
