Description
Technical Field
The invention relates to a boiler, in particular to a boiler taking biomass bales as fuel.
Background
The method is that a part of straws are used as fuel by farmers to burn fire or feed livestock, and the rest of straws are directly burned in the field to return to the field. Although the straw treatment mode is simpler, the soil fertility is improved, the fire prevention is not facilitated, and serious haze is formed by straw combustion so as to pollute the environment. In recent years, the nation has strictly forbidden to burn the straws in the field, so as not to influence the planting of crops in the next season, the nation is popularizing to bundle the straws in the field, and then transporting the bundles out of the field for other purposes, and part of the straws can be made into granular fuel, but the cost of the granular fuel made from the straws is higher, and the cost of the granular fuel is not superior to that of other fuels. The simplest treatment mode for baling straw is to directly use the baling straw as fuel, but because baling is relatively large and loose, a common boiler cannot directly burn baling straw. And because biomass straw fuel has low heat value and long flame, sugar and soil are contained in the straw, sticky coking can be generated when the biomass straw fuel burns at high temperature in the boiler and is hung on the heated pipe wall of the boiler to be difficult to clean, and the more the coking is hung, so that the heat efficiency of the boiler can be gradually reduced, finally, the boiler cannot supply heat, and finally, the boiler can be scrapped.
