Problems solved by technology

[0004] Most of the composite fuels sold on the market contain a considerable amount of pulverized coal, and their production will inevitably consume a large amount of raw coal resources, so not only the cost remains high, but also the energy consumption is high and it is not environmentally friendly

Abstract

The invention provides a compound fuel and a production method thereof. The compound fuel comprises the following components by weight percent: 15-35% of domestic sludge of a sewage treatment plant, 15-70% of carbon powder after biomass carbonization, 10-50% of biomass raw material which is uniformly crushed and 0.8-2% of coalification agent. The production method comprises the following steps: performing pretreatment on the raw material, including the crushing of the biomass raw material, the carbonization of the biomass raw material into the carbon powder and the preparation of the coalification agent; stirring: adding the sludge, the coalification agent, the carbon powder and the biomass after crushing into a stirring device according to the weight percentage for uniform stirring; tempering: placing a mixture obtained after well stirring for 8-72 hours; forming: preparing and forming the mixture after tempering; and drying: performing drying and dehydration on the mixture after forming. The compound fuel can save energy, protect an environment and reduce cost.

Description

technical field [0001] The invention relates to a composite fuel, in particular to a composite fuel with sludge and biomass as main raw materials and a production method thereof. Background technique [0002] Sewage treatment plants discharge a large amount of waste all year round, that is, sludge, which cannot be reused and will cause secondary pollution to the environment. [0003] Biomass refers to all organic substances formed directly or indirectly by photosynthesis of green plants, including plants, animals, microorganisms and their excretion and metabolites other than fossil fuels (coal), such as straw, trees and other lignocellulose ( Lignin for short), agricultural product processing waste, agricultural and forestry waste, and livestock manure and waste in the process of animal husbandry production. It is renewable, widely distributed, and low-pollution. If it can be used for synthetic fuel, it can not only effectively reduce the cost, but also reduce pollution an...
