Study Case of Optimization Analysis on Energy-saving in Paper Mill Power-Heat System

Abstract

According the characteristics of both steam and

power was supplied in paper mill power plant， 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 load distribution. The case study of one

paper mill showed that the optimization model was helpful and

the coal consumption can decrease 4.7% aiding with the model
