Based on the analysis of the existing dedusting method of advanced coal-fired combined cycle, a new dedusting concept was proposed for the high temperature and high pressure dusty gases according to the theory that the flow direction of the gas but the dust in dusty supersonic gas flow changes and the gas velocity decreases after the dusty supersonic gas flow passes through the oblique shock.

The construction and features of a PG6581B gas turbine-based coke-carrying thermal partial-gasification coal-fired combined cycle system are described along with a calculation and analysis of the performance of the PG6581B gas turbine when firing coal gas of medium and low calorific value.

An advanced coal-fired combined cycle power generation technology which has high efficiency and excellent environmental performance should be actively developed in China.

According to the feasibility and application of the coke carried heat coal fired combined cycle, to set up a whole static simulation program of the system, a basic model for the bubbling fluidized bed boiler was developed and adopted to do some calculation.
