Recently, the National Development and Reform Commission and the National Energy Administration have clearly proposed that biomass-fired boiler heating is a green, low-carbon, clean and economical renewable heating method, which is suitable for small and medium-sized industrial parks heating and urban heating. They also required that all regions of the country propose policies and measures to promote the development of heating of biomass-fired boilers and establish a clean and renewable heating system in cities and towns, on the basis of the actual situation of coal consumption and natural gas supply and demand in the region as well as biomass resources and heating markets.
