Embodiment Construction

[0011] Raw material formula one (parts by weight) of composite briquette

[0012] Anthracite (crushed) 25

[0013] Papermaking waste paper pulp (calculated as dry matter) 25

[0014] Bituminous coal (crushed) 20

[0015] Coal slime (calculated as dry material) 20

[0016] Raw material requirements and production process are as follows:

[0017] The anthracite and bituminous coal in the above formula are pulverized and passed through a 30-40 mesh sieve, and the coal slime is a paste passed through a 40-60 mesh sieve. The water content of papermaking waste paper pulp is 65-70%, and the water content is deducted when batching. The water content of the coal slime is 7-10%, and the water content will be deducted during the batching.

[0018] After the compound briquettes are batched according to the above raw material formula, they are stirred and mixed evenly by a mixer, and then the briquettes are pressed through the briquettes. The calorific value of the four raw materials...

Abstract

The recipe of composite briquette includes anthracite, inflammable waste papermaking pulp slurry, and coal sludge from coal washing. The present invention can eliminate the environmental pollution caused by waste papermaking pulp slurry and coal sludge and lower briquette producing cost by 15-20 %, while ensuring the stable combustion and avoiding black smoke produced during combustion. In addition, the burnt cinder contains potassium, phosphate and other components essential for crops and may be used in improving soil.

Description

technical field [0001] The invention relates to a fuel, in particular to a formula for producing compound briquettes from various combustible solid fuels. Background technique [0002] In the prior art, the briquettes used in people's lives and industries are made of anthracite as a raw material, and clay or lime is used as a binder, and the anthracite is pulverized and then mixed with the binder and then pressed into briquettes by a briquette machine. Due to the concentration of anthracite production areas, long-distance transportation has increased production costs, and because coal prices have continued to rise, production costs have increased again. At present, the waste paper pulp discharged from paper mills seriously pollutes the environment. It contains a large amount of combustible short plant fibers (pulp), which has not been used as fuel, but has been discharged with sewage. Now people also gradually reduce the effect of coal slime, and t...
