Description
Summary:With the practical experience in the UCG power generation test in Huating Coal Group of China, nine ways of enhancement of efficiency of Underground Coal Gasification -Integrated Gasification Combined Cycle (UCG-IGCC) Power Plants are put forward which include selection of proper gasification agent flow rate, proper steam concentration in gasification agent, proper O 2 concentration in gasification agent, the appropriate oxygen making process, appropriate overall rate of air separation system, increase in temperature of gasifiers, control of the length of the reduction zone, increase in the inlet temperature of gas turbines, utilizing the sensible heat of the coal gas.
