The features of four energysaving processes are profoundly understood through a comprehensive analysis of steam powered circulating systems used by energysaving processes of C.

A new indirect air cooling system for steam condenser in power plant was presented,in which the steam power cycle was coupled with the positive and negative sequence refrigerating cycle by means of a special dual-phase change heat exchanger.

In this paper I make a explanation on the contrasting method that is used to teach the content of the steam power cycle in the course of Fundamental s of Heat Engineering,which breaks the traditional step-by-step sequence teac hing method.

A new selfpressure lifting steam power cycle was proposed based on the steam injector of supersonicsteamwater twophase flow.

This paper discusses the feasibility of using the rate of regeneration work as a new economical performance in evaluating the steam circulation.

Optimal multiperiod operational planning for steam power system of petrochemical industry;

Study on steam power system operational optimization strategy;

Design and implementation of steam power system operational planning optimization software;

Integration and operation optimization of utility systems;

An analysis on the negative impact of steam parameter change on utility system and process operations was conducted.

An improved genetic algorithm(IGA) is presented for the optimization of utility system which can be described as the problem of nonlinear programming (NLP).
