Wiang Haeng coal-water fuel preparation and gasification, Thailand - task 39
- and others
In response to an inquiry by the Department of Mineral Resources (DMR) in Thailand, the Energy & Environmental Research Center (EERC) prepared a four-task program to assess the responsiveness of Wiang Haeng coal to the temperature and pressure conditions of hot-water drying (HWD). The results indicate that HWD made several improvements in the coal, notably increases (HWD). The results indicate that HWD made several improvements in the coal, notably increases in heating value and carbon content and reductions in equilibrium moisture and oxygen content. The equilibrium moisture content decreased from 37.4 wt% for the raw coal to about 20 wt% for the HWD coals. The energy density for a pumpable coal-water fuel indicates an increase from 4450 to 6650 Btu/lb by hydrothermal treatment. Raw and HWD coal were then gasified at various mild gasification conditions of 700{degrees}C and 30 psig. The tests indicated that the coal is probably similar to other low-rank coals, will produce high levels of hydrogen, and be fairly reactive.
