摘要录用
The distribution, composition and yield of pyrolysis products of coal water slurry (CWS) have an important influence on the efficient combustion/gasification of coal water slurry. In this paper, for different concentrations of coal water slurry, rapid pyrolysis is carried out in a heating furnace, and the yield, composition and content of pyrolysis gas and pyrolysis char produced were measured and analyzed. The effects of temperature and slurry concentration on the pyrolysis characteristics of CWS were studied. It has been shown that with the increase of temperature, the yield of pyrolysis volatiles increases and the residue char decreases while the pyrolysis tar becomes rare. The main compositions of volatile matter are H2, CO, CH4, and H2O. With the increase of temperature, the yields of H2 and CO increase, and the yield of CH4 rises first and then descends. The difference in the concentration of coal water slurry mainly affects the distribution and yield of pyrolysis products. The research results provided a reference for understanding the formation characteristics of primary pyrolysis products of coal water slurry.
