Abstract

Abstract: Energy-saving dispatching is a main measures of energy-saving and emission reduction of the electric power industry in China. A single indicator of power supply coal consumption can’t thoroughly reflect the energy-saving and emission reduction in coal-fired power plants. As the energy-saving dispatching index, the power supply coal consumption rate, SO₂ and NO_x emission, EAF, net loss and water resources consumption were selected. The emergy analysis method was implemented to sort the integrate index for determining the order of the dispatching. Based on the comparison of calculation data, the evaluation method was proposed. The evaluation method can reasonably reflect the situation of the energy-saving and emission reduction in the coal-fired power plants and can provides a reference for energy-saving dispatching.

Key words: energy-saving and emission reduction, coal-fired power plant, energy-saving dispatching, emergy analysis, sorting
