Abstract

The invention relates to the technical field of biomass molding fuel, in particular to a biomass molding fuel binder, and a preparation method and addition mode thereof. The biomass molding fuel binder is obtained by the following steps: mixing oil sludge and kaolin, uniformly carrying out stirring, and then carrying out drying to obtain a first mixture; mixing the first mixture and oil sludge with a same mass as in the first step by stirring to obtain a second mixture; and grinding and sieving the second mixture to obtain the biomass molding fuel binder. The preparation method of the biomassmolding fuel binder is simple and convenient, the raw material sources are wide, and the obtained biomass molding fuel binder not only can improve strength and heat value of biomass molding fuel, butalso can reduce energy consumption for molding the molding fuel. Meanwhile, kaolinite components contained in the binder can trap alkali metal elements and alkaline earth metal elements in ash duringcombustion, so that the ash fusion point of the biomass fuel is improved, slag contamination and particle release caused by boiler combustion of biomass are effectively inhibited, and a new way is provided for resource utilization of oil sludge.

Description

technical field [0001] The invention relates to the technical field of biomass briquette fuel, and relates to a biomass briquette fuel binder, a preparation method and an addition method thereof. Background technique [0002] As a clean and renewable energy source, biomass has outstanding advantages such as high energy density, easy transportation and storage, and can replace lump coal. Therefore, it has broad application prospects, but the current briquette fuel has poor physical properties. , High energy consumption for forming, high alkali metal content lead to problems such as slagging and pollution of combustion boilers and release of particulate matter. [0003] As a by-product of oil extraction, oil sludge is difficult to effectively utilize. Because of its cohesiveness and high calorific value, it can be used as a binder for biomass briquettes. However, due to its high viscosity, it is not easy to mix evenly with pulverized biomass raw materials, so it needs viscos...
