The Safe And Economic Operation Of The CHP System

This paper analyses the current heat supply situation of Baotou second thermalpower plant and works out the thermal loads of the heat network and feed water andbackwater temperature of inner and outer heat network during the heating seasonsaccording to the different outdoor temperature in winter. The paper designs a adjustmentmethod which can be used to adjust heat network thermal loads based on"quality-quantity adjustment method" and brings forward a optimal heat supplyoperation mode and relational measures which can be used in remodeling,configuring,adjusting operation and operation management of the heat network system according tothe principle of keeping the highest generate electricity rate and coefficient of heatsupply. On the basis of a unified performance evaluation system based on electricity, thispaper estimates the performance index of heat supply process of adjustment method andconcludes that cogeneration would develop very well and get good economical benefitsif using the mode of low-grade heat supply in this plant. The paper is significant for thisplant to operate safely and economically, cut down the cost of power generation and heatsupply and enhance the economical benefits.
