The first is a new or retrofit project using a dedicated biomass boiler; the second is that the project is equipped with corresponding environmental protection facilities, and the pollutant emissions must meet the natural gas boiler emission standards; the third is that the project is completed and put into operation by the end of 2020; the fourth is that the project does not limit the technical route , Including biomass direct-fired boilers (using agricultural or forestry biomass or formed fuels as fuels), biomass gasification boilers (using biogas, biomass gasification gas, etc. as fuels), and biomass cogeneration using heat-set electricity, etc. Fifth, state subsidies are not required for project construction and operation.

The "Notice" requires all localities to propose policies and measures to promote the development of biomass boiler heating in response to the local natural gas supply and demand situation, biomass resources, and heating market conditions, build clean and renewable heating systems in towns, and actively promote clean heating of biomass boilers Application in small and medium-sized industrial parks, small and medium-sized towns, reduce coal consumption and save natural gas.
