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

The thermal power generation unit of high-efficient energy-saving environment friendly

Technical field

Involved in the present invention is with solid, liquid, gas fuel combustion to the field, and the chemical energy of fuel is changed into heat energy, changes the pressure potential of steam again into, changes the mechanical energy of steam turbine again into, changes the thermal power generation unit of the electric energy of generator again into; As coal-fired thermal power generation unit, fuel oil thermal power generation unit, combustion gas thermal power generation unit

Background technology

Prior art is in the work of thermal power generation unit, and fuel and air react, and the part of oxygen that is actually in fuel and the air in 21% the oxygen reacts, and the result who causes is: fuel is excessive in the combustion reaction, the oxygen wretched insufficiency; Efficiency is low, the excess waste of the energy, and the serious pollution of environment, low in economic efficiency

Summary of the invention

Main purpose of the present invention is to solve the thermal power generation unit in the course of the work, and the oxygen deficiency is by increasing oxygen supply, make the oxygen deficiency, fuel combustion is insufficient, and it is excessive to become oxygen, the abundant completing combustion of fuel makes the instantaneous effective combustion rate of fuel reach the upper limit (UL) value.Its energy savings has three: the abundant completing combustion of first fuel, energy savings; It two is that exhaust emissions reduces 79%, and the heat that tail gas is taken away reduces 79%, energy savings; It three is that nitrogen has reduced 79% in the combustion adjuvant, and the nitrogen oxide in its tail gas reduces significantly.The scheme of specifically dealing with problems is: directly supply with excessive purity oxygen (or liquid oxygen) directly for thermal power generation unit boiler furnace, different fuel takes the oxygen of different proportion to supply with, and is that the instantaneous effective combustion rate of fuel reaches the upper limit (UL) value.Reduce tail gas working media total amount about 79%, thereby reduce the heat energy loss of tail gas significantly, reduce the discharging of nitrogen oxide in the tail gas in a large number; Further improved the hot merit conversion ratio.Thereby reach the efficiency of combustion that improves the thermal power generation unit, energy-conservation, reduce discharging consumption reduction; Significantly improve the economic benefit and the social benefit of thermal power generation unit; The ecological environment that protection is human improves rate of energy, saves human Limited resources, improves social benefit and economic benefit.Benefit the world, universe, bounties our children and our children's children.

The specific embodiment

By air separation equipment, airborne oxygen separation is come out, supply with excessive purity oxygen (or liquid oxygen) directly for thermal power generation unit boiler furnace.
