Abstract:As a response to the depletion of fossil fuels increasingly and alleviate the effects of global warming on human existence, world energy will increase energy efficiency and promote the development of new energy into national strategies, distributed energy to best of boom as 21st century science, has received extensive attention and application from around the world.
China’s energy shortage and environmental pollution has become increasingly serious and energy-saving industry, system design of thermal power plant is of great significance.
Thermal power plant thermodynamic system typically consists of a number of interactions, coordination, and has a different function subsystem, mainly with steam reheat systems, heating systems, heat recovery systems, evaporators bypass system and drainage system.
The N-125-13.34/550/550/-unit power plant system for the design, the main five programmers have been designed and will be reflected in the baby. Different design concepts, different design parameters, are to work out the most perfect design, to get the most energy-saving, efficient heating systems. Each of these scenarios is detailed on the regenerative heating system; water desecrating system; calculation of auxiliary heating system, additional system in principle. Comparison of the last of five programmers, selected a best solution. Last, Summarizes on the selected device.
Key words: Thermal system；Back to heat heating system；Water supply oxygen system; Auxiliary heating system
