Optimization model of trubines and boilers load distribution in paper mill power plant

According the characteristics of both steam and power was used in paper mill, the optimal running model of the coal-fired power-heat system was researched in this paper. The power plant's physical structure was researched, the superstructure was established and the boiler and turbine running model was analyzed. With the help of mathematical programming, each turbine unit optimal loads were obtained when the same power and steam were produced, moreover, the minimum coal cost were calculated with each boiler unit optimal coal feeding distribution. The case study of one paper mill showed that the coal consumption can decrease 4.7% aiding with the optimization model of power-heat system.
