Analysis and discussion on application of semi-coke in fixed-bed crushed coal pressurized gasifier
Jinshi Park Branch of Jinneng Holding used fixed-bed crushed coal pressurized gasification technology to produce ammonia and methanol.The raw coal for the gasifier was anthracite lump coal.In order to further expand the types of raw coal for gasifier,a trial burning experiment was conducted in the company by blending with semi-coke to expand the types of raw coal.The gasifier operating conditions,gas composition,consumption per ton ammonia,and changes in gas liquor production were introduced under semi-coke blending proportions of 20%,30%,50%and 100%respectively.The economics of blended combustion of semi-coke in gasifier was analyzed,and the trial combustion data could provide practical guidance for raw coal structure adjustments in similar enterprises.
