The development and manufacture of coal briquettes
- Chinese Academy of Sciences (China)
Three different kinds of coal briquettes, i.e., gasification briquette, boiler briquette and easy ignition roast briquette, have been developed and produced with the authors` patent binder. The gasification briquette is made from fines of anthracite or coke, hot stability agent and patent binder. It has been used as a substitute of anthracite lump in gasifiers to produce fuel gas and syngas. The three year`s performance of this briquettes in the TG-3MI gasifier has given good economic benefits. The boiler briquette is made from bituminous coal fines, sulphur-fixing agent, combustion-supporting agent, waterproofing agent and patent binder. It can keep its original shape in water for one month. The combustion results of the boiler briquette in a 4t/h coal-fired boiler have shown that heat efficiency increased by 20%, the total suspended particles decreased by 80%, and emission of both SO{sub 2} and Hap were reduced as compared with the raw coal. The easy ignition roast briquette is made from fines of charcoal, anthracite or coke, oxidant and binder. It is convenient and safe to use in that it can be lit with a match or a piece of paper easily and burn continuously for 90 minutes without smoke and odor. It can be used as a fuel for roasting food for a picnic.
