High-efficient, energy-saving and environment-friendly thermal power generating unit

Abstract

The invention discloses a high-efficient, energy-saving and environment-friendly thermal power generating unit and relates to the field of the thermal power generating units which can burn solid, liquid or gas fuel, convert chemical energy of fuel into thermal energy, further convert the thermal energy into pressure potential energy of water vapor, further convert the pressure potential energy into mechanical energy of a steam turbine, and further convert the mechanical energy into electrical energy of a power generator; such as a coal-fired thermal power generating unit, a fuel-fired thermal power generating unit, a gas-fired thermal power generating unit and the like. Pure oxygen (or pure liquid oxygen) which is separated from the air through an air separation device is directly supplied into a burning chamber of the thermal power generating unit for replacing the original air in an excessive manner, thereby leading the fuel to be fully and completely burned, and leading the instantaneous effective burning rate of the fuel to achieve the highest limit value. The high-efficient, energy-saving and environment-friendly thermal power generating unit can save energy from three aspects: 1) the thermal power generating unit can lead the fuel to be fully and completed burned, thereby saving the energy; 2) the thermal power generating unit can reduce the exhaust emission by 79% and reduce the heat taken away by exhaust by 79%, thereby saving the energy; and 3) the thermal power generating unit can reduce nitrogen in a burning resistant agent by 79% and greatly reduce nitrogen oxides in the exhaust, thereby greatly reducing the loss of the thermal energy of the exhaust and further improving the thermal-power conversion rate. Therefore, the thermal power generating unit can improve the burning efficiency of the thermal power generating unit, save the energy, reduce the emission and reduce the consumption.

Description

technical field [0001] The field that the present invention relates to is to burn solid, liquid and gaseous fuels, convert the chemical energy of the fuels into thermal energy, then into the pressure potential energy of water vapor, then into the mechanical energy of the steam turbine, and then into the electrical energy of the generator Thermal power generating sets; such as coal-fired thermal generating sets, fuel-fired thermal generating sets, gas thermal generating sets...
