With the call of national green industrialization and green urbanization, China's environmental protection boiler market will show a rising trend in the future. Various relevant policies and product standards of environmental protection boiler will be gradually implemented and formulated. In the next five years, coal will still be the main energy source for industrial environmental protection boilers, and the installation of environmental protection facilities for flue gas emission will be the mainstream, and the main way will be supporting boiler desulfurization, denitration and dust removal equipment.

Commercial and civil small and medium-sized environmental protection boilers will use clean energy as the main fuel. With the help of state subsidies for environmental protection boilers, their market will gradually expand, replacing the original coal-fired boiler market, Gas boilers and other environmentally friendly boilers have corresponding policy support.
