Research On Energy-saving Methods For 300MW Units Thermal System Of Wuan Power Plant

For the current China’s economic policy adjustment, the power structure has undergone great changes, for the light industrial and municipal life is on the rise consumption, and for the heavy industry night electricity proportion was relatively reduced. In order to meet the load adjustment, the capacity of 300 MW is relatively large or larger units to participate in the work of power grids, power generation standard coal consumption is likely to far exceed the design value. Whlie China is vigorously promoting the economy from extensive to saving, so the coal saving power plant which is a major event, so this paper conducts the research energy saving measures of the power plant is of far-reaching significance.This paper mainly through the establishment of new power plant in Wuan 300 MW thermal power unit, thermal performance test model, and according to the thermal performance test results of Wuan power plant thermal system on the problems existing in the study of diagnosis. Mainly include the important components in the thermal system of steam turbine ontology analysis of the energy saving measures, and energy-saving diagnosis for thermal system. For optimal operation of the steam turbine steam distribution has carried on the experimental study, studied the sequence valve operation, the operation of the advanced measures, such as sliding pressure operation for guiding optimal operation curve drawing by field data. The cold end optimization study, an important factor affecting the unit heat consumption- vacuum are analyzed in energy conservation, research and the relevant technology and measures the factory unit were determined. And the technology of power plant energy saving measures are proposed.
