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

Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings.

[0035] figure 1 It is a perspective view which shows the whole form of the burner for biomass solid fuel boilers concerning one Example of this invention.

[0036] Such as figure 1 As shown, there is a boiler body 12 that uses the combustion heat obtained by burning biomass solid fuel to heat the water flowing through the internal pipeline, that is, a boiler body 12, and a unit that burns solid fuel, that is, a combustion unit, is provided at the bottom of the boiler body 12. In the device 11, a fuel supply unit 10, which is a unit for supplying solid fuel, is provided in front of the boiler body 12 and the combustion device 11.

[0037] Here, in the case of the above-mentioned fuel supply unit 10, any unit may be used as long as it can continuously and periodically control and supply biomass fuel such as wood pellets in a predetermined size state (a spring screw is ...

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 ...
