Embodiment

[0026] Raw material selection and dosage:

[0027] Raw coal powder: 50 kg of mixture of anthracite, coking coal and bituminous coal;

[0028] Vegetable fuel powder: 20 kg of crop straw and sawdust mixture;

[0029] Sulfur-fixing agent: 2 kg of lime;

[0030] Binder: 5 kg of clay, 2 kg of bentonite;

[0031] Hardener: 2 kg of cement;

[0032] Oxygenating agent: 1 kg of magnesium nitrate.

[0033] The raw materials are weighed and mixed respectively, stirred with water, extruded or rolled into strip-shaped rod-shaped granules, and naturally dried or oven-dried to become a finished composite fuel.

[0034] Experiments show that the composite fuel produced by the method of the invention has water resistance and wet strength, and is convenient for storage and transportation. During the combustion process, the firepower of the fuel is uniform, the burning speed is moderate, and the ash has strength. The burned ash is easy to fall off in the form of particles from the burning pa...

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...
