Backpressure steam turbines are widely used in industrial production and offer significant economic benefits. So, what types of backpressure steam turbines are there?
1. Back-pressure steam turbine
The exhaust steam working pressure of a back-pressure turbine can be customized according to customer requirements. This model is widely applicable to dust-to-energy generation in industries such as metallurgy, building materials, chemical plants, and other similar sectors, and its reliability can be automatically adjusted. As a high-pressure power plant designed for energy-saving upgrades, its exhaust steam—typically at around 435℃ and 3 MPa to 4 MPa—can be used to power high-pressure generating units. The power generation capacity of this unit is directly proportional to the heat supply, meaning it operates on a heat-to-power principle. Since all the steam used for heating involves no cold loss, the energy-saving effect is remarkably significant.
2. Extraction-backpressure steam turbine
In addition to condensing steam heating, various steam pressures can also be supplied via steam extraction. Each extraction pressure can be automatically adjusted to its rated value in response to changes in heat demand. This system is particularly suitable for thermal customers requiring two different steam pressures, thereby avoiding wasteful energy consumption.
3. Condensing Steam Turbine
Condensing steam turbines in various forms—such as high-pressure, ultra-high-pressure, sub-high-pressure, medium-pressure, sub-medium-pressure, and low-pressure wet steam—can be widely used in power plants, thermal power stations, and standby power plants as prime movers to drive generators for power generation. These turbine types can also be converted into non-regulated extraction turbines; in addition to generating electricity, they can extract a portion of the steam for heating purposes (with the extraction pressure varying depending on operating conditions). Back-pressure turbines also fall into this category, as they can utilize the lower-parameter steam discharged from back-pressure units to perform additional work.
4. Extraction-condensing steam turbine
We offer a complete range of single-extraction and double-extraction steam turbines, tailored to meet the diverse heating and other energy needs of different customers. Since the extracted steam does not enter the condenser, this design significantly reduces energy losses throughout the entire system, enhancing its energy-saving and environmental benefits. The amount of extracted steam can be adjusted freely, and the stable pressure of the extracted steam can be automatically regulated. The control and regulation equipment is highly reliable. This model can also operate continuously in pure condensing mode, providing independent power supply.
