Problems solved by technology

The current biomass solid particle fuel has the following problems: poor durability, low combustion calorific value and combustion rate
Its disadvantages are: the raw materials of the fuel are all crops, the combustion calorific value is low, the combustion durability is poor, and the lignin content in the raw materials is low, so it is not easy to form. In addition, when the pellet fuel is burning, oxygen is not easy to enter the interior of the fuel center , resulting in insufficient fuel combustion and low combustion rate

Abstract

The invention discloses a high-combustion-value biomass solid granular fuel which is prepared from following raw materials, by weight, 25-30 parts of pine wood chips, 30-40 parts of China fir wood chips, 5-10 parts of bagasse, 15-20 parts of crop straw and 1-5 parts of a combustion-promoting agent. The solid granular fuel is reasonable in raw material formula. Through mutual cooperation among the raw materials, the fuel is good in formability, durability and combustion durability and is high in combustion heat value and combustion rate. Through strict control of granularities of the raw materials, gradients are formed among the granularities of the raw materials so that the fuel is ensured in the formability, the durability, the combustion durability, the combustion heat value and the combustion rate. Combustion of the fuel is promoted and the combustion rate is increased greatly since the fuel contains the combustion-promoting agent composed of ammonium bicarbonate and calcium peroxide.

Description

technical field [0001] The invention relates to a biomass fuel, in particular to a high combustion value biomass solid particle fuel. Background technique [0002] Biomass solid particle fuel refers to the use of crop straw and other agricultural production residues, which are compressed into specific shapes by special equipment to increase its density. When using CO 2 Net emissions are approximately zero, NO X , SO 2 The low emissions are conducive to reducing the phenomenon of straw burning in vast rural areas and improving the atmospheric environment. [0003] At present, biomass solid fuel is mainly obtained by compressing agricultural and forestry waste such as sawdust, shavings, wood powder, and crop straw, rice husk, etc., into a certain shape, strength and density after mechanical pressure and heating. The current biomass solid particle fuel has the following problems: poor durability, low combustion calorific value and low combustion rate. [0004] For example,...
