Thermal Power Units Start And Stop Procedure Energy-saving Optimization And Risk Control

In the process of rapid development of the economy, while excessive human consumption of energy, seriously polluted their survival of the Earth and space, energy conservation, environmental protection, to meet the current needs of human development, the " sustainable development" has become the current human urgent critical issues and future joint follow.Power generation fuels in primary energy than the major world power is always higher than the growth rate of economic growth, generating energy in primary energy use increases year by year. Improve the energy efficiency of thermal power plants once, as far as possible to reduce the cost of electricity, reduce heat consumption, save fuel and improve the thermal power plant efficiency and reduce environmental pollution, has become the main development direction of thermal power technology, advanced industrial countries. Technological transformation of existing power plants face many challenges content, in order to reduce the scope of the study, carried out put some losses, combined with the existing coal-fired units of thermal power characteristics, this paper thermal unit commitment process as the starting point, from unit commitment process pooled analysis of the problems, in-depth analysis of the problem based on the analysis of thermal power saving start-stop process optimization and the corresponding risk analysis of control, to achieve the purpose of energy saving.Thermal power unit operation optimization technology is based on optimization theory as a guide, Based on the actual operation of the unit main and auxiliary equipment; Fully optimized test results and comprehensive analysis, Establish a set of run optimization procedures and rational optimization theory, The unit can best run in a variety of load range and the most reasonable parameter matching。Energy saving target, Reduce power plant operating pressure, Process for325MW thermal unit commitment, Requirements for commissioning and operational characteristics of the normal start of the unit, the size of the repair after the entire group of start-up and normal deactivation process conditions segment, Tried a variety of energy-saving measures in the way of running, Our practice annual economic benefit, And the feasibility of and promote the value of five of optimization of, To achieve annual economic benefits of1.1863million yuan.
