    Two ways to use coal briquette in industry briquetting

    Dec 17, 2018 Coal briquettes should have high heat and cold strength and good thermal stability. When briquetting in a reasonable process and choose the right coal type, the technical indexes of coal briquette can meet the requirements of industrial boilers, furnaces, and gasifiers. Process. The coal briquetting process is simple with a small investment. Generally, binders are used to briquette coal, but the binderless briquettes are held together by the natural bonding mechanisms of coal. The coal upgraded through this process can be used in place of any other high ranking coal without the need of technical or engineering alterations at the power stations to allow for coal combustion. 1. A cold coal briquetting process characterised by mixing fine coal with a binder comprising 5-15% sugar solution of a concentration of at least 25% by weight and up to 5% of hardening accelerator for the sugar solution selected from iron oxide, calcium carbonate, calcium phosphate and aluminium oxide, each optionally with an acid, and p-toluene sulphonic acid, and forming the mixture into ...
