Technical and economic studies on the optimisation of prospective coal-fired power stations
The paper considers problems of choosing rational parameters of thermal power plants on fossil fuel. A technique for comparison of the energy and economic efficiency of prospective coal-fired power plants is described. The optimisation results of parameters of combined-cycle plants with coal gasification at low and high-temperature levels and steam turbine plants on supercritical steam parameters are given. The diagrams of relationships between the net efficiency and minimum specific capital investments in installations are constructed. The rational area for application of compared installations is shown.
