There are three main theories binder briquetting mechanisms from the view of interaction of binders and the pulverized coal: solid bridge connecting, electrostatic attraction and liquid bridge connecting respectively. In this paper, the process of non-binder briquetting mechanism and briquetting mechanism with binder is also reviewed.

used as fuel. Briquetting is a process of binding together pulverized carbona-ceous matters at specific pressing, often using various binders (J.F. Martin et al., 2008) [11], (N. Altun et al., 2003) [12]. The common forms of briquettes are the coal briquettes and the biomass briquettes. The binders can be organic or inor-ganic agents.

Unlike raw wood pellets, energy dense torrefied biomass pellets or briquettes share important traits with coal which make them a promising alternative clean fuel to use directly in coal plants. They are brittle (not fibrous, like raw pellets), so they can be pulverized just like coal before being fed into the coal boiler. They also have similar BTU content to coal and are water resistant, so ...

A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700 F. and typical pressures between 200 and 3,000 psi, according to known liquefaction processes.
