Anonymous users2024-02-15TRT ---blastfurnacetopgasrecoveryturbineunit, hereinafter referred to as TRT, Chinese translated as furnace top (surplus) pressure turbine, generally more accurately called blast furnace gas.
Residual pressure ** turbine generator set.
TRT uses the pressure energy and heat energy in the top gas of the blast furnace to do work through turbine expansion.
to drive the generator to generate electricity, and then the mechanical energy is transferred through the generator.
It becomes electric energy and is transmitted to the power grid, which can be about 30% of the blast furnace blast energy. The amount of electricity emitted by the TRT unit is related to the pressure and flow rate of the blast furnace gas, which is generally 30 kWh per ton of iron.
40 kWh. The blast furnace gas can increase the power generation by 36% by dry dust removal, and every 10 increase in temperature will increase the output of the turbine by 10%, so that the maximum power generation of the TRT unit can reach 54 kWh tons of iron.
The characteristics of the device are: it does not consume any fuel, it is the most economical power generation equipment to eliminate noise pollution and pollution-free, and it can replace the pressure reducing valve group to adjust and stabilize the pressure on the top of the furnace.

Anonymous users2024-02-14The by-product gas of the blast furnace is used to generate electricity, the gas from the top of the blast furnace is generally more than 150kpa, and the gas pressure supplied to the user is generally about 10kpa, so the pressure of the blast furnace gas must be reduced. TRT came into being, TRT is mainly composed of turbines, generators and their auxiliary systems, the turbine converts the pressure energy and thermal energy of blast furnace gas into rotational kinetic energy, and then drives the generator coaxial with the turbine to generate electricity, it does not consume fuel and can reduce noise, it is a green power generation project, which can consume about 30% of the energy of the blast furnace blower.
In layman's terms, there are blades on the rotor of the turbine, and the gas blows the blades to rotate the rotor, and then drives the generator to generate electricity.

Anonymous users2024-02-13TRT ———blastfurnacetopgasrecoveryturbineunit, hereinafter referred to as TRT) blast furnace gas residual pressure turbine power generation device is a secondary energy device that uses the by-products of blast furnace smelting to ——— the pressure energy and heat energy of blast furnace top gas, so that the gas does work through the turboexpander, converts it into mechanical energy, and drives generators or other devices to generate electricity. The device not only relieves the energy released by the pressure reducing valve group, but also purifies the gas, reduces the noise, stabilizes the pressure at the top of the furnace, improves the conditions of blast furnace production, does not produce any pollution, and can realize pollution-free power generation, which is recognized as an energy-saving and environmental protection device by modern international and domestic iron and steel enterprises.
Introduction to the process.
The gas produced by the blast furnace is dedusted by gravity, purified and dusted, and the pressure is about 140kPa and the temperature is less than 200. The gas with a certain energy with a dust content of less than 10mg nm3 enters the turbine to expand through the imported butterfly valve, starting valve, fully enclosed hydraulic inlet plug-in valve, emergency shut-off valve and adjustable static vane of TRT, and the turbine drives the generator to generate electricity. The expanded gas passes through the fully enclosed hydraulic outlet plug-in valve and is sent to the main gas pipeline behind the pressure reducing valve group.
In this way, the TRT and the pressure reducing valve group form a parallel relationship to realize the control of the top pressure of the blast furnace. After the inlet plug-in valve and before the outlet plug-in valve, there is a bypass pipe and a quick-opening and slow-closing bypass valve (referred to as the bypass quick-opening valve) in parallel with the TRT, which is used for the smooth transition between the TRT and the pressure reducing valve during the emergency shutdown of the TRT, so as to ensure that the pressure at the top of the blast furnace does not fluctuate greatly, and the low-pressure gas from the TRT and the pressure reducing valve group is then sent to the blast furnace gas cabinet and the user.
Differential protection. It is the main protection of the transformer, which is installed according to the principle of circulating current. It is mainly used to protect various phase-to-phase short-circuit faults that occur inside the winding of double-winding or three-winding transformers and their lead-out lines, and can also be used to protect transformers from single-phase inter-turn short-circuit faults. >>>More
