specific Embodiment approach 1

[0011] Specific embodiment 1: In this embodiment, the biomass solid molding fuel additive consists of 20% to 30% Al by weight percentage 2 o 3 , 15% to 30% Fe 2 o 3 It is mixed with 40% to 65% kaolin.

[0012] During the straw burning process, the biomass solid briquette fuel additive in this embodiment can react with alkali metal salts and chlorides to generate high melting point substances, thereby achieving the effect of improving the ash melting point and making the ash melting characteristics of the straw biomass solid briquette fuel close to medium coal.

[0013] Due to the addition of the biomass solid molding fuel additive in this embodiment, the ash melting point of the straw biomass solid molding fuel has been significantly improved, so it can also be co-fired with garbage and coal for power generation and heat supply, which broadens the scope of straw biomass solid molding. Fuel usage range.

specific Embodiment approach 2

[0014] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the biomass solid molding fuel additive consists of 22% to 28% Al by weight percentage 2 o 3 , 17% to 28% Fe 2 o 3 It is mixed with 44% to 61% kaolin. Others are the same as the first embodiment.

specific Embodiment approach 3

[0015] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the biomass solid molding fuel additive is made of 25% Al by weight percentage 2 o 3 , 20% Fe 2 o 3 And 55% kaolin mixed composition. Others are the same as the first embodiment.

Abstract

A biomass solid forming fuel additive relates to a biomass fuel additive. The invention settles the problems of easy slag bonding, easy ash accumulation, inadequate burning, low fuel usage factor, lowcombustion efficiency and serious corrosion of combustion device by the flue gas generated in burning, which are caused by low ash fusion point of biomass solid forming fuel that is produced by usingstalk as raw material. The additive of the invention is prepared by mixing Al2O2, Fe2O3 and kaolinum. The biomass solid forming fuel additive according to the invention can effectively increase the ash fusion point of stalk. The biomass solid forming fuel using the biomass solid forming fuel additive according to the invention is not easily generated with in-furnace slag bonding and ash accumulation in combustion process. The usage factor of biomass solid forming fuel is effectively increased for more sufficiently burning the biomass solid forming fuel.

Description

technical field [0001] The invention relates to a biomass fuel additive. Background technique [0002] Biomass solid briquette fuel has the advantages of easy transportation and storage, convenient use, clean and environmentally friendly, and renewable. It can replace fossil energy such as coal and petroleum, reduce dependence on non-renewable resources, and ensure national energy security. my country is a large agricultural country with rich straw resources, and converting straw into biomass solid briquette fuel is of great benefit to environmental protection, resource utilization and farmers' income generation. [0003] However, the ash melting point of biomass solid briquette fuel produced with straw as raw material is low, which leads to easy slagging, easy ash accumulation and insufficient combustion during the combustion process of biomass solid briquette fuel, which reduces fuel utilization and combustion efficiency; and The flue gas produced by combustion seriously ...
