Abstract

The invention discloses sludge-containing biomass fuel. The sludge-containing biomass fuel is prepared from the following raw materials in parts by weight: 20 to 30 parts of maize straws, 15 to 20 parts of rice husks, 10 to 15 parts of paper product, 10 to 15 parts of dry sludge and 3 to 5 parts of mineral residues. The fuel takes organic sludge as one part of the fuel, provides a way for the organic sludge and realizes recycling of the sludge.

Description

technical field [0001] The invention belongs to the technical field of biomass fuel, and in particular relates to a sludge-containing biomass fuel and a preparation method thereof. Background technique [0002] Biomass fuel is the burning of biomass materials as fuel, mainly agricultural and forestry waste. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. Biomass fuel mainly refers to biomass molded fuel, which is a new type of clean fuel that uses agricultural and forestry waste as raw materials and undergoes processes such as crushing, mixing, extrusion, and drying to make various shapes and can be directly burned. The composition of biomass fuel has become a hot spot in the development of new energy. Contents of the invention [0003] The first object of the present invention is to provide a biomass f...
