About biomass boiler and biomass fuel.

Raw materials for biomass boilers are widely available, as long as they are idle wooden materials after photosynthesis, such as rice husk, sunflower seed husk, sorghum stalk, corn stalk, bean stalk and so on. After being pressed into columnar granular fuel by a special molding mechanism at high temperature and high pressure, it can be put into a special boiler to generate enough heat, and the generated slag can still be used as potash fertilizer to supply crops. According to the relevant person in charge of Shenyang Environmental Protection Bureau, biomass energy raw materials can realize "0" emission of sulfur dioxide and carbon dioxide.

As for the cost, the key depends on whether the fuel source there is sufficient and the price is appropriate.
