The Study Of Technology And Application About Acquiring Heat Energy By Electricity

The percentage of electricity in consumption of terminal energy source represents the extent of development and civilization of a country. China electitricity supply and demand has some extent relives after late 1990's. Electricity surplus occurs in some areas, and deference between peak and trough of power network is increasing. Power utilization is not equilibrium. But the power network lack of peaking ability. It reduces the operating efficiency of power set, causes waste of energy sources, and influences security and quality of power supply. With development of economy, demand for environmental protection is higher than before. Environment pollution, sulfur dioxide, coal ash and fume relives from coal fired boiler, such air pollution and noise polution have become the most important causes to inhibit development of economy and society. These make clean electricity heating mode become a major trend.Electricity heating technology can achieve automatic control and utilize energy resources effective. It can supply the thermal that system needs to the comsumers, and has no waste. And it can make the best use of the low trough surplus electricity resources. This makes the technology has unique enviramental protection advantage compared with other energy sources. So the electricity heating technology has wide long term potential.This paper combines the charicteristic of Heilongjiang Province power system such as supply exceeds demand, heating cycle in winter is long, arcola and personal heating is too much, air pollution is serious ect to rearch the realization machinism of electricity heating technology and actulization technology of electricity heating or heat storage. By contrast and analyze economic technology, the paper brings forward principles in choosing power and mode of electricity devices and medium of electricity heat storage when design electricity heating system, accomplishs overall design of control system. The paper also achives the conclusion that electricity heating technology is feasibility and advanced and has obvious ecomomic benefit and social benefit by analyzing economic technology and social benefit of electricity heating project in existence in Heilongjiang Province.With the development of craft and technology, new demands and technique means will appear incessantly. Further researchs can base on contents that the paper describes.The electricity heating technology that this paper describes is able to be applied in current produce actual condition of heating system in China-...
