I produce biomass straw fuel. It is said that there are many household biomass fuel boilers for heating in Tianjin this year. I wonder which ones are in use.

According to the regulations, it seems that Tianjin began to implement biomass boilers in June 1, using new boiler fuels. Tianjin Wuqing has a Sigma boiler company engaged in production and research in this field. Other cities are not clear. How to use it, how to convert energy, and whether it is converted are completely unclear, but you can check it out. Attached is a picture, I hope it will help everyone.
