Quantitative Study Of Steam Turbine Unit' Variable Load Optimal Operation

In recent days power plant's responsibilities is so heavy because as a main energy consumption enterprise at the moment of our country advocate to save energy, lower energy consumption and reduce pollutants. As a energy source worker ,we must make great efforts to cast about for fresh ways to lower energy consumption,what is now became a significant subject in save energy. Although through buiding some lower energy consumption power plants can save energy , it has the characteristics of large investment, long construction period.So we need to look for new break throuth in available plants on the label. Now more and more utility-type unit participate in piching peak,what parameter values makes the coal consumption rate minimum is worth reseaching For the variable load plant ,as the unit′s load altering Operational Limits altering,too. Through optimizing operation parameters to achieve the purpose of reducing coal consumption. On the unit for variable condition analysis,define minimum of operation parameters in different load coal consumption for the power plant and staff has practical significance to provide basis. This article chooses is now more common north, While previous literature research relatively few condenser type direct air-cooling unit NZK600-24.2/566/566 as calculation. Comprehensive consideration of the environmental factors on the operation parameters influence And joined the is often ignored pipe pressure loss of research Separately calculated the several typical load of condenser vacuum, heater end poor and feed water pump outlet pressure, superheater desuperheating water flow should be achieved values. In the above variable condition on the basis of study, combining power plant hot economic state equation of optimal initial pressure calculation model, using matlab language programming calculation early pressure value and curves are drawn as power plant operation personnel's reference.
