Analyze the waste heat utilization technology in detail

At present, in the power structure of China's power plants, coal-fired power plants account for more than 80% of the country's total power generation, even by 2020, coal-fired power plants will still generate more than 70% of the electricity. SO2, NOx and dust from coal incineration are still the primary sources of atmospheric pollution. Efforts to improve power utilization, reduce coal consumption as much as possible, and reduce greenhouse gas and SO2 emissions remain the top priority for environmental protection.

Therefore, saving power and protecting the environment is an important part of China's sustainable development strategy, which has become a basic national policy of our country. It is an effective way to save power, protect environment and improve enterprise economic benefit to build thermal power plant and complete cogeneration and cocooling. It is also an inevitable choice for our country to implement the strategy of saving power and protecting the environment.

To carry out comprehensive utilization of resources is a long-term great skills economic policy of our country, and also a long strategic policy in the development of our national economy and society, it has important meaning on saving resources, improving the environmental situation, improving economic benefits, and completing the optimal allocation and sustainable development of resources. On the one hand, a lot of medium and low grade waste heat is discharged in the production process of ore furnace, and on the other hand, it consumes a lot of electric energy.

In order to convert medium and low grade waste heat into electricity and recover it for the production of mineral heat furnace, and then further reduce the energy consumption and save power for the production of mineral heat furnace, the production enterprises of mineral heat furnace can significantly reduce the purchase of electricity to social power plants. At the same time, it can avoid the heat island phenomenon caused by the direct discharge of waste heat from the mineral furnace into the atmosphere, and because it reduces the fuel consumption of the social power plant or the self-provided power plant of the mineral furnace production enterprise burning fuel, it can reduce the emission of carbon dioxide and other incineration waste and help protect the environment.
