Semi-coke is one of the main by-products of coal chemical industry. It has the disadvantage of high pulverization rate

and it is easy to raise dust and difficult to transport. Using biomass as a binder to make semicoke into briquette products can overcome this shortcoming. This research carried out an experimental study on the strength and combustion characteristics of the forming briquette with Wulgai lignite semi-coke and biomass. The effects of biomass type

biomass ratio

forming pressure and biomass particle size on the drop strength

compressive strength and water immersion strength of semi-coke briquette were investigated

and the cold forming parameters were recommended. Taking the Wulagai semi-coke coal with 60% biomass as an example

when the forming pressure is above 90 MPa

the drop strength of the semi-coke coal can reach 80%

and the compressive strength and immersion strength can reach 4 MPa. In addition

the semi-coke biomass briquette has good combustion characteristics and can be used as an excellent civil fuel.
