The reason why China does not pay attention to wave power generation is the lack of core technology. According to relevant public information, the lack of core technology has always been the reason why China does not pay attention to the development and utilization of wave power generation. The principle of wave power generation is to convert wave power into compressed air to drive an air turbine generator to generate electricity. When the wave rises, the air in the air chamber is pushed up. The pressurized air passes through the positive pressure water valve chamber and enters the positive pressure cylinder and drives the air turbine on the shaft extension end of the generator to make the generator generate electricity. When the wave falls, the air A negative pressure is formed in the room, causing the air in the atmosphere to be sucked into the cylinder and drive the air turbine on the other shaft extension end of the generator to generate electricity without changing its rotation direction.
What is a turbine? What is a hydraulic turbine? Please tell me
TRT----------BlastFurnaceTopGasRecoveryTurbineUnit, hereinafter referred to as TRT,
The Chinese translation is top (residual) pressure recovery turbine, which is generally more accurate It is called blast furnace gas residual pressure recovery turbine generator set.
TRT uses the pressure energy and thermal energy in the blast furnace top gas to do work through turbine expansion to drive the generator to generate electricity. The generator then converts the mechanical energy into electrical energy and transmits it to the power grid, which can recover the blast furnace blast energy. About 30%. The power generated by the TRT device is related to the pressure and flow of the blast furnace gas. Generally, the power generated per ton of iron is 30 kWh to 40 kWh. Dry dust removal of blast furnace gas can increase power generation by 36%, and every 10°C increase in temperature will increase turbine output by 10%, allowing the maximum power generation of the TRT device to reach 54 kWh/ton of iron.
The characteristics of this device are: it does not consume any fuel, is the most economical power generation equipment that eliminates noise pollution and is pollution-free. It can replace the pressure reducing valve group to adjust and stabilize the furnace top pressure.
Also known as turbine and turbine. Turbine is the transliteration of English turbine, derived from the Latin word turbo, which means rotating object. The working conditions and working fluids of turbines are different, so their structures are diverse, but the basic working principles are similar. The most important component of the turbine is the rotating element (rotor or impeller), which is installed on the turbine shaft and has blades evenly arranged along the circumference. The energy of the fluid is converted into kinetic energy when it passes through the nozzle during the flow. When it flows through the rotor, the fluid impacts the blades, pushing the rotor to rotate, thereby driving the turbine shaft to rotate. The turbine shaft drives other machinery directly or through a transmission mechanism to output mechanical power. Turbines can be divided into water turbines (used as the power source of hydropower stations), steam turbines (used in thermal power plants, ship propulsion, etc.), and gas turbines (used as the propulsion power of jet aircraft, ships, etc.) according to the different working fluids used. power, as well as power plants, small power stations for peak loads, etc.) and air turbines (can only be used for small power), etc.
Hydraulic turbine--When water flows from a high-water level reservoir along a channel to a hydraulic turbine at a low water level, the potential energy of the high-water level water turns into kinetic energy, which drives the turbine to rotate. The tailwater flowing through the turbine flows along the waterway. nowThe only purpose of a hydropower turbine is to serve as a power source for a hydropower station to drive a generator to generate electricity.
Steam turbine-its working fluid is steam, which has thermal energy. Steam comes from boilers burning fossil fuels or from steam generators heated by nuclear power plants. The high-temperature and high-pressure steam they generate is sent to the steam turbine through the nozzle at high speed, driving the rotor to rotate and output power. The steam flow rate is very high and the turbine rotor size is small, so the speed can reach 10,000 rpm. Steam turbines are mainly used in thermal power plants to drive generators to generate electricity; they are also used in large ocean-going ships and submarines as main engines to drive propellers and propel ships.
Gas turbine--it, together with the compressor and combustion chamber, becomes the three main components of the gas turbine device. Air is supplied to the compressor and compressed into compressed air of higher pressure and temperature. It flows into the combustion chamber to mix and burn with fuel, forming a high-temperature, high-pressure, and high-speed gas flow. It flows into the gas turbine and drives the gas turbine to rotate. The shaft outputs mechanical power. The speed of the gas turbine reaches tens of thousands of revolutions per minute. The most widely used modern gas turbine is as the propulsion power of jet aircraft. Some are used as ship power, power plants, small power stations for peak loads, and as the power of gas pumps for transporting natural gas over long distances. Gas turbines used to power locomotives and automobiles are still under development and testing.
There is also a gas turbine used in rocket engines. It serves as the power for a delivery pump that pressurizes rocket propellant (fuel and oxidizer). A gas generator uses chemical reactions to generate the required high-temperature gas. , blowing the turbine to rotate and driving the delivery pump to operate.
In addition, there are also turbines that use compressed air as the working medium to push the rotation of the turbine, which can only be used as a small power. This type of turbine is called an air turbine.
