Problems solved by technology

[0003] However, the preparation of biomass pellet fuel is still immature at present, especially the problem of slagging of straw-based biomass pellet fuel is common, but there is no efficient solution at present. The existing patent document CN 108070418 A discloses a biomass fuel anti-caking The slagging agent specifically discloses that "the composition of the biomass fuel anti-slagging agent is: calcium magnesium carbonate 75.00%-76.0%, silicon dioxide 6.5%-7.1%, potassium permanganate 17.5%-18.0%, the present invention uses carbonic acid Magnesium calcium is used as an anti-slagging agent. During the combustion process, Mg element reacts with Si, K, Na and other elements inherent in corn stalks that can cause slagging, and a new compound K is formed. 2 Mg(SO 4 ) 2 And make it have anti-slagging performance", the patent document believes that Si and K can cause slagging, but add silicon dioxide and potassium permanganate to the anti-slagging agent, and even if K 2 Mg(SO 4 ) 2 , but K still exists in the pellet fuel, which can only play a very small anti-slagging effect. Obviously, the patent document cannot be established in theory. The method of slagging rate

Abstract

The invention mainly relates to the technical field of biomass particle fuel processing, and discloses a method for reducing the clinkering rate of straw biomass particle fuel. The method comprises the following steps: carrying out crushing, carrying out fermenting, carrying out washing, carrying out water treatment and carrying out granulation. According to the provided method for reducing the clinkering rate of the straw biomass particle fuel, the method is simple, no harmful metabolites are generated, the method is green and environmentally friendly, the content of alkali metals in straw can be effectively reduced, the combination of the particle fuel is firm, the clinkering rate is obviously reduced to 7.3%, and the combustion condition of the particle fuel is obviously improved. The crushed straw particles are small, and then water is added for soaking, so that the alkali metals in the straw particles is diffused into the water with a low concentration, and the alkali metal content of the straw particles is reduced after centrifugation.

Description

technical field [0001] The invention mainly relates to the technical field of biomass particle fuel processing, in particular to a method for reducing the slagging rate of straw-like biomass particle fuel. Background technique [0002] my country is a large agricultural country. Sawdust, bamboo chips, branches, straw, and plant shells are all agricultural wastes. At present, most areas burn these wastes on the spot, and only a small part of nutrients can enter the soil. , the released carbon dioxide has caused great harm to the environment; biomass pellet fuel is made of wood chips, bamboo chips, branches, straw, plant shells, etc., through professional machinery, special technology, without any chemical additives, high pressure Low-temperature compression-molded granular fuel can fully use agricultural waste for combustion. [0003] However, the preparation of biomass pellet fuel is still immature at present, especially the problem of slagging of straw-based biomass pellet f...
