In the field of environmentally friendly boiler products such as waste heat boilers, market demand is very strong, because waste heat boilers are needed in high energy-consuming industries such as cement and glass, and waste heat boilers are also being tested in large power plants to achieve environmental protection and energy conservation.

        In addition, the more subdivided industries of boilers, the higher the requirements for technical parameters. Therefore, they have formed industry leaders in their respective subdivisions, such as Huaguang shares in the field of waste-to-energy boilers, Huaxi Energy of waste heat boiler power generation, and natural gas power boiler Hangzhou Guoguo in the field, Dongfang Electric in large-scale thermal power plant boilers, etc. In their respective subdivisions, the gross profit margin of their products is relatively high. Therefore, the current 15 times price-earnings ratio of the boiler sector is indeed underestimated, not to mention that most of these stocks have ample contract orders, thus locking up the performance growth trend in the next one or two years.

       From the perspective of China's current energy structure, with the call of the country's green industrialization and green urbanization, China's energy-saving and environmental protection boiler market will show a rising trend in the future. Various factors such as the development and changes of raw materials comprehensively influence the decision.

       Under such circumstances, the state once concentrated its efforts on environmental improvement on boiler rectification. Strongly promote new boilers that use clean energy. It is necessary to accelerate the progress of boiler energy saving and emission reduction technology, increase investment in scientific research, increase boiler thermal efficiency, reduce boiler heat loss, increase energy utilization, reduce energy consumption, and reduce operating costs while reducing boiler pollutant emissions. Environmental protection is of great significance.
