PMC solid fuel preparation method

Abstract

The invention relates to the technical field of solid fuel production, in particular to a PMC solid fuel preparation method which comprises the following steps that S1, fuel raw materials in a raw material bin are mixed and then fed into a screening machine, and after impurity screening, the fuel raw materials are fed into a grinding and drying machine; s2, the grinding and drying machine is connected with a bag type powder collector, a hot blast stove supplies heat to the grinding and drying machine, and the fuel raw materials are conveyed into the bag type powder collector through a winnowing machine after being ground and dried, wherein the fuel raw materials comprise the following components in parts by mass: 50-70 parts of carbon powder, 10-15 parts of saw wood powder, 15-25 parts of paraffin, 6-10 parts of 95% alcohol, 10-15 parts of an enhanced swelling agent, 10-12 parts of an oxidizing agent, 6-8 parts of a catalyst, 5-8 parts of a modified sulfur fixation additive, 10-12 parts of a smoke suppressor and 35-55 parts of water. According to the invention, not only can the sufficiency of the PMC solid fuel during combustion be improved, but also the stability of a sulfur fixation product can be improved and the pollution rate of sulfur dioxide can be reduced.

Description

technical field [0001] The invention relates to the technical field of solid fuel production, in particular to a method for preparing PMC solid fuel. Background technique [0002] PMC solid fuel can promote the full combustion of PMC charcoal, and play a role in combustion and energy saving. The PMC solid fuel contains an oxidant that provides an oxygen source, which can decompose oxygen under high temperature conditions to promote the complete combustion of PMC. In addition, the catalyst without corrosive substances can effectively reduce the dissociation energy of oxygen and the activation energy required for carbon combustion, strengthen the combustion of PMC, and play a role in strong combustion and energy saving. [0003] However, in the process of daily use, some problems will still be found, such as: 1. Although the solid fuel can fully burn the fuel when it is burned, because the fuel is a whole piece of solid material, the burning time will be longer It takes a lo...

Problems solved by technology

[0003] However, in the process of daily use, some problems will still be found, such as: 1. Although the solid fuel can fully burn the fuel when it is burned, because the fuel is a whole piece of solid material, the burning time will be longer It takes a long time to complete the work, and it is difficult to completely burn the central area of ​​the fuel during the combustion process; 2. This solid fuel contains a sulfur fixer, and the solid fuel formed under the action of the Calcium sulfate, the sulfur product, will be thermally decomposed into sulfur dioxide again due to high temperature, increasing pollution
