Low-temperature waste heat from flue gases of waste incineration plants for power generation

Low-temperature waste heat from flue gases of waste incineration plants for power generation

Waste incineration plants generate a large amount of flue gas in their daily operation, which contains high-temperature heat as well as low-temperature waste heat. These low-temperature waste heat actually has a high value for power generation, and if it can be effectively recovered and utilised, it will bring multiple benefits.

The main advantages of utilising the low-temperature waste heat in the flue gas of a waste incineration plant for power generation are as follows:

Resource recovery: by generating electricity using low-temperature waste heat, the energy that would otherwise be wasted can be converted into electricity, improving the efficiency of resource utilisation and reducing energy consumption.

Clean energy: The fuel used in the power generation process of waste incineration plants is mainly waste, which is a relatively clean energy source compared to fossil fuels, as the waste itself needs to be disposed of, and by incinerating it and utilising the low-temperature waste heat to generate electricity, the impact on the environment can be reduced.

Reducing greenhouse gas emissions: By utilising low temperature waste heat for power generation, it can reduce the emission of harmful substances in the flue gas, especially greenhouse gases, and contribute to the mitigation of global climate change.

Increase power supply: By utilising low temperature waste heat for power generation, waste incineration plants can increase power supply and provide more power resources for local residents and industries.

Economic benefits: By recycling low-temperature waste heat to generate electricity, waste incineration plants can generate additional economic benefits by reducing the cost of waste disposal and also selling the electricity generated.

However, it should be noted that waste incineration plants need to do a good job of treating the waste gas in the process of recycling low-temperature waste heat to ensure that the emissions meet environmental standards. In addition, the recycling of waste heat also requires certain technical facilities and investment, so the economic and environmental benefits need to be considered comprehensively in implementation. Overall, the use of low-temperature waste heat in the flue gas of waste incineration plants to generate electricity is a promising technology that is of great significance in promoting sustainable development and resource recycling.
