The present invention is to be related to the device of energy power generation and machinery equipment field, and more particularly to supercritical water heat transfer characteristic fills
It puts, and in particular to supercritical water burn-out-proof dry systems device.
Background technology
The energy is the material base of mankind's activity.In the sense that the development of human society be unable to do without high-grade energy
Appearance and advanced energy technology use.In the world today, development, the energy and the environment of the energy are that the whole world, the whole mankind are common
Same concern and the major issue of Chinese society economic development.
Thermal power generation is one of the main generation mode in China, three big host equipments of the station boiler as firepower power station,
Along with the development of China's Thermal Power Generation Industry, wherein supercritical unit has effect that is most significant energy saving and improving environment
Fruit.Super critical boiler technology is coal-fired power generator set the most advanced in the world, and there is low coal consumption, good environmental protection, technology to contain
Measure the characteristics of high.
Supercritical unit has unrivaled economy, and the single unit power generation thermal efficiency reaches as high as 50%.It is super to face
The generating efficiency of the boundary's unit Subcritical Units mainly used more recent than China are higher by about 10%, 6 are higher by than supercritical unit~
8%.If supercritical unit simultaneously using low Nox technology, reduce in combustion 65% oxynitrides and other have
The formation of evil substance, and desulfurization degree can surpass 98%, it can be achieved that energy-saving, environmentally friendly purpose.And nuclear power is with its exclusive advantage
