Description
- The present invention belongs to the flied of energy and power technology.
- Cold demand, heat demand and power demand are common in human life and production. It is an important way to obtain and provide power by the conversion of thermal energy into mechanical energy. In general, the temperature of heat source reduces and varies with the release of heat. When fossil fuels are used as the primary energy, the heat source has the dual characteristics of both high-temperature and variable temperature. This makes it is difficult to transform more heat energy into mechanical energy using the power device based on a single thermal cycle. For high-quality fuel, the traditional gas-steam combined cycle can be used to obtain a high thermal efficiency. However, there are still some problems to be solved, such as high cost, large investment and low thermal efficiency to be improved.
- Take the vapor power device with the outside combustion for example, its heat source has the dual characteristics of high-temperature and variable temperature. For those vapor power devices based on the Rankine cycle, the material's temperature resistance and pressure resistance abilities and safety concerns limit the parameters of the cycle's working medium. Therefore, there is a big temperature difference between the working medium and the heat source, which leads to big irreversible loss and low efficiency. This means that there is great potential to improve the thermal efficiency.
