Applied Program Of Boiler In Power Plant On Thermodynamic Calculation And Exergy Analysis

Coming to light, the question of energy sources is a significant question for discussion that people all along focus attention upon, and energy crisis enhances people' s energy-saving consciousness. We must put the reasonable use of energy on an important station, except to study and open up all kinds of new energy. It is highly important that we do energy-saving work of energy-consuming equipment. Boiler is a primary energy-consuming equipment in power plant. Therefore, exergy analysis of boiler in power plant has a significant meaning.Presently, the method of heat balance is widely used in boiler in power plant, and it analyses the status of using energy from the quantity of energy. With the development of science and technology, the method of exergy analysis to exactly open out the heat-using status of boiler comes into use, and it analyses the status of using energy from the quantity and quality of energy. Compared with the method of heat balance, the method of exergy analysis not only reflects external losses of boiler in power plant, for example, waste heat loss and external heat losses, but also opens out inner losses in the course of energy conversion, for instance, nonreversible losses. Furthermore, the method of exergy analysis may perfectly analyse the status of using energy of all kinds of boiler surface. Accordingly, the method of exergy analysis may perfectly and concretely weigh perfect thermodynamic degree, and exactly open out the tache and process ofmaximal losses, and offer the object and countermeasure for saving energy.The thesis adopts the method of heat balance based on the first law of thermodynamics . the method of exergy analysis based on the first and the second law of thermodynamics, and structured method of projecting the program, and make the applied program of boiler in power plant on thermodynamic calculation and exergy analysis. This program does thermodynamic calculationn heat balanceable calculation and exergy losses exergy of boiler in power plant and all kinds of boiler surface; it can do changed condition analysis. The results of this program open out all kinds of losses and the place to bring these losses of boiler in power plant, and offer scientific gist for developing energy-saving work.
