Waste Heat Recovery Generator Sets: Energy-Saving and Environmentally Friendly!

Oct 13, 2023


Waste Heat Recovery Generator Sets are a novel type of generator that utilizes the waste heat generated by generator sets. These systems employ a new method of waste heat recovery, replacing traditional gas generator sets, resulting in significant energy savings and meeting the requirements of energy conservation and environmental protection.


1: Principles of Waste Heat Recovery Generator Sets

Waste Heat Recovery Generator Sets harness waste heat for power generation. These systems are typically categorized as coal-fired waste heat generator sets, natural gas waste heat generator sets, biomass waste heat generator sets, and waste heat generator sets for industrial waste. Coal-fired waste heat generator sets utilize the residual heat in coal combustion gases. Through equipment like waste heat boilers, waste heat steam turbines, waste heat circulation pumps, cooling towers, chillers, steam turbines for power generation, transformers, and control systems, the waste heat from coal combustion is converted into steam, cold water, or hot water, providing the necessary thermal energy or electricity for industrial production. These systems are known for their high energy efficiency, low power generation costs, low operating costs, long service life, and environmental friendliness.


2: Applications of Waste Heat Recovery Generator Sets

Waste Heat Recovery Generator Sets are commonly used in industrial sectors such as metallurgy, chemical engineering, natural gas, power plants, coal mines, waste incineration facilities, construction, and educational institutions. These enterprises or units generate a substantial amount of waste heat, often in the form of hot water or steam. Utilizing waste heat recovery generator sets to harness this waste heat is a highly efficient, environmentally friendly, and energy-saving technology. The application of waste heat recovery generator sets can significantly reduce energy consumption, lower production costs, decrease pollution, and protect the environment. It represents a crucial means for industrial enterprises to achieve energy savings and emission reductions.


3: Advantages of Waste Heat Recovery Generator Sets

  1. a. Waste Heat Recovery Generator Sets effectively utilize waste heat, saving energy and reducing emissions. They represent an energy-efficient and environmentally friendly method of electricity generation.

  2. b. These systems have high power generation efficiency, reaching 40% to 60%, which is 3 to 5 times higher than coal-fired power generation efficiency.

  3. c. The operating costs of Waste Heat Recovery Generator Sets are low since waste heat serves as the primary heat source, significantly reducing power generation costs.

  4. d. The investment costs for waste heat recovery generator set equipment are relatively low, with waste heat boiler investment costs being only one-third to one-fourth of coal-fired boiler costs.

  5. e. These systems have a significant environmental protection effect as waste heat boilers can fully utilize the heat in waste gases, reducing pollution of the atmospheric environment.


Waste Heat Recovery Generator Sets are a novel type of generator that harnesses the waste heat generated by generator sets. They employ a new waste heat recovery method, replacing traditional gas generator sets, resulting in substantial energy savings and aligning with energy-saving and environmentally friendly requirements. Utilizing waste heat from generator sets not only helps conserve energy but also meets environmental conservation standards.
