Our 10~30MW extraction back pressure steam turbine generator set is specially designed for medium and large-scale combined heat and power (CHP) projects, industrial steam supply and waste heat utilization. It features dual steam supply modes: adjustable extraction steam and back pressure exhaust steam, which can simultaneously meet process steam demands of multiple pressure levels with ultra-high cascade energy utilization efficiency.
All steam after power generation is supplied to external processes without condensation loss, ensuring stable power output while providing high-quality steam for petrochemical, paper, metallurgy, textile industries and district heating in industrial parks. It is especially ideal for large enterprises with complex steam loads and multi-pressure requirements.
Equipped with high-strength forged rotor and optimized high-efficiency flow path, the unit features stable operation, strong load variation resistance and supports 24/7 heavy-duty continuous running. The advanced DEH digital electro-hydraulic control system realizes precise linkage adjustment of extraction pressure, back pressure and power load, ensuring strong condition adaptability and safe operation. With compact structure, easy maintenance and long service life, the unit fully utilizes main boiler steam, industrial by-product steam and waste heat steam to achieve high-efficiency energy utilization and cost reduction.

High-efficiency cascade energy utilization
The turbine realizes efficient cascade utilization of steam energy. Steam first expands to generate power, and then provides graded external steam supply for industrial use, delivering a significantly higher energy utilization rate than conventional turbine units.
Dual steam supply for multi-grade process demand
It features dual steam supply modes of extraction steam and back pressure exhaust steam, which can meet process steam requirements of different pressures and diverse industrial applications, with extremely strong adaptability to complex working conditions.
No condensing loss, maximum energy output
Without condenser cold source loss, all steam is fully applied to industrial production or heating. The comprehensive energy efficiency is far superior to traditional condensing steam turbines.
Stable power generation + reliable steam supply
The unit maintains continuous and stable power generation, while precisely stabilizing extraction pressure and back pressure at all times, ensuring zero impact on the safety and stability of production steam supply.
Flexible load adjustment for complex working conditions
With flexible load adjustment performance, the turbine can adapt to steam parameter fluctuations and variable steam consumption loads, perfectly suitable for complex working conditions of chemical, papermaking, metallurgy and CHP cogeneration projects.
Compact structure, stable operation, low maintenance
Designed with a compact structure, the equipment operates smoothly with low vibration. It features long-term operational stability and effectively reduces daily operation and maintenance costs.
Ideal for industrial CHP & district heating projects
It is highly applicable to industrial park centralized heating, enterprise self-owned cogeneration and waste heat recovery projects, bringing outstanding economic and energy-saving benefits for industrial energy systems.
