Burner for boiler using biomass solid fuel

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.

Description

technical field [0001] The present invention relates to a burner for a biomass solid fuel boiler, and more specifically, to a burner for a boiler using a solid fuel such as wood pellets that has attracted attention as a biomass energy source. [0002] The present invention specifically realizes a new type of combustion method in which the fuel is conveyed by a screw in the form of water circulating inside and burned in a specific section where air (oxygen) is supplied by the blower, so that even the high heat generated during combustion can be ensured. The durability of the screw can be improved, and the slag and ash can be satisfactorily processed, and the size of the boiler using solid can be greatly reduced, so that the overall structure can be simplified and the production cost can be reduced. [0003] In addition, the present invention relates to a biomass solid fuel boiler burner with improved action and function, which uses a hollow tube to form a screw for discharging ...

AI Technical Summary

Problems solved by technology

[0010] That is, the moving grate method such as a transmission belt (chain) has problems in the production of a high-efficiency boiler (burner) due to the complicated mechanical structure that leads to excessive production costs and the size of the lower part of the boiler. It is not suitable for the characteristics of making small boilers such as household use

[0011] In addition, the burner-type and crucible-type combustion methods mainly used for burning wood pellets have the problem of dealing with the large amount of slag and ash generated when burning low-quality pellets, so it is important to provide the root cause of the defects. , and from the perspective of burner structure, it is actually not easy to manufacture commercial and industrial medium and large boiler burners
