Hybrid fuel and method for preparing the same

Abstract

The invention discloses a composite fuel production method, which is characterized by the following: mixing the raw coal powder, vegetable fuel powder, sulfur-fixed agent, adhesive, hardener and oxygenation agent according to proportion with water; producing particle through particle moulding equipment; drying naturally into product. The invention reduces the environmental pollution, which is fit for industrial and civil fuel heat supply device.

Description

technical field

[0001] The invention proposes a composite fuel and a production method thereof in the fuel field. Background technique

[0002] Before the present invention was proposed, coal was usually directly used for combustion or pulverized injection combustion, and was made into coal-water slurry for liquefaction combustion. But no matter the combustion method, it is mostly carried out in the form of raw coal. Due to the different historical ages, environmental conditions, and types and varieties of organic matter produced by raw coal, its basic physical and chemical indicators such as combustion value, combustion performance, and ash content also vary widely. Therefore, in the environment where raw coal is basically burned, the combustion effects are different. Some produce a large amount of combustion flames, resulting in incomplete combustion, and some produce a large amount of unburned cinders, which also cause incomplete combustion, resulting in coal fuel combus...
