Combustion characteristics of briquette fuels from sorghum …
The higher compressive strength may be elastic in nature, and the lower compressive strength may have improper alignment of particles. The compressive strength is one of the most important characteristics of a briquette which determines the stability and durability (Kpalo et al. 2020).

The effect of different treatment conditions on biomass binder
The briquettes with the solid part (5.1%, dry basis) and the liquor part (18%) were prepared separately, and their compressive strength was measured to be 2.28 and 1.34 MPa, accordingly. It was revealed that the binding ability of liquor in the binder is weak (the compressive strength of briquette without binder is 1.22 MPa).

The coal particle size also plays an important role in binderless briquetting. It is believed that the briquette compressive strength increases with increasing percentage of small size and fine particles, i.e., the higher the content of small particles in the lignite briquettes, the higher the briquette compressive strength (Sun et al. 2014).
