Description

Biomass particle boiler

Technical Field

The utility model relates to a living beings granule boiler belongs to boiler technical field.

Background

The biomass particle boiler uses biomass particles as fuel to burn and heat, and the biomass particles have the characteristics of wide sources and reproducibility, so that the biomass particle boiler has the advantage of low use cost compared with coal, natural gas, electric boilers and the like. However, compared with fuels such as coal and natural gas, the biomass fuel has a low heat value and a small heat quantity, and the heating efficiency of the boiler is relatively low, so how to improve the heat energy utilization rate of the biomass fuel is a key technical problem of the biomass particle boiler.

In order to solve the problems, some biomass particle boiler enterprises also take some improvement measures to improve the heating efficiency. One way is to increase a combustion-supporting structure, such as the environmental-friendly and energy-saving biomass fuel boiler disclosed in patent CN201720053007.9, in which a gas pipe and an oil injection pipe are added in a combustion chamber, and combustion is supported by natural gas and fuel oil, although the heating effect can be obviously improved, the boiler cost and the operation cost are greatly increased, and the essence of the boiler is not a biomass boiler in the complete sense. In addition, the coal economizer utilizes the waste heat of the flue or designs a combustion channel and a heat exchange channel in the boiler into a complex structure to prolong the heat exchange time, and the like, and the methods have the problem of high cost and are also not suitable for small biomass fuel boilers.
