To further promote the implementation of clean production and strengthen the prevention and control of industrial pollution, the National Environmental Protection Administration focuses on addressing pollution issues in the industrial sector. Saving energy and improving energy efficiency are key to resolving environmental problems. The primary source of pollution in industrial development comes from the use of coal-fired boilers, which have led to severe smog in many industrial cities across the country. In response to national requirements, efforts are being made to vigorously overhaul coal-fired boilers, improve the ecological environment, and enhance the quality of life for the people. Yining Boiler, in response to the national call, has made significant efforts to phase out coal-fired boilers and develop new gas heat transfer oil boilers.

Coal-fired boilers will gradually phase out of social production. In terms of alternatives to coal-fired boilers available today, while electric boilers do not pose environmental pollution issues, their operational costs are high, making them economically unfeasible for users. Many factories would abandon the use of electrically heated thermal oil boilers due to their high costs. Heavy oil and light diesel oil boilers have moderate operational costs but still present unresolved environmental pollution issues, which continue to pollute the air. Biomass pellet fuel boilers have slightly higher operational costs than gas boilers. In this light, the optimal choice for replacing coal-fired boilers is to promote the use of natural gas boilers, which are known as "clean energy." The challenge then becomes how to achieve high heating efficiency with natural gas boilers after the boiler replacement.
