CPT Series Surplus Pressure Turbines

CPT Series Surplus Pressure Turbines

In many industrial fields such as building materials, chemical industry, metallurgy, coal mining, papermaking, and cogeneration, a large amount of waste heat and surplus pressure is generated during the production process. The waste heat and surplus pressure recovery technology not only recycles a large amount of exhaust gas that would otherwise be discharged into the atmosphere and cause environmental pollution, but also generates considerable power generation benefits. The entire thermal system does not burn any primary energy source, so it will not cause any pollution. This is of positive significance for energy conservation and emission reduction, reducing dust and carbon dioxide emissions, mitigating the greenhouse effect, and protecting the ecological environment.
The CPT series surplus pressure turbines can be customized according to the specific conditions of customers, maximizing power generation benefits and reducing costs.

Features & Advantages of CPT Series Surplus Pressure Turbines

  • Wide range of available differential pressure media (flue gas, steam, ORC, natural gas, NO₂, etc.)
  • High-efficiency radial/mixed-flow turbine design
  • Various structural forms (single-stage high-speed, multi-stage high-speed, multi-stage single-shaft, etc.)
  • Multi-output design (can be designed to drive generators, compressors, water pumps and other equipment)

Case Analysis

A factory in Shandong directly discharged a certain amount of waste steam (3T/h during the day, 4.5T/h at night) with a pressure of 3BarG, which not only wasted energy but also polluted the environment. Our company developed a two-stage radial mixed-flow surplus pressure turbine with automatic adjustment function for it, with a maximum recovered mechanical power of 450KW and a power generation capacity of 400 degrees/hour.
