Technical research on briquette for pyrolysis from low-rank bituminous coal in Naomao Lake
This study utilizes low-rank coal from the Naomuhua district of Xinjiang as the primary material,combined with pregelatinized starch and thermosetting phenolic resin as a composite binder,to produce briquettes through cold pressing technology.It examines how factors such as the binder composition and quantity,coal particle size distribution,pressure,and moisture content affect the mechanical strength of the briquettes,aiming to develop an efficient method for low-rank coal formation.Under optimal conditions,the briquettes achieved a drop strength of 95.7%,thermal stability of 93.2%,cold pressing strength of 11.2 kN per piece,and thermal strength of 1.3 kN per piece,all meeting the relevant standards.
