conditions of turbulence and temperature. Biomass can be represented chemically as CH. 2 O. Therefore, to burn 30 pounds of biomass, you need to supply 32 pounds of oxygen, which is accompanied by 105.3 pounds of nitrogen in the air (air is 21 percent oxygen and 79 percent nitrogen). Hence, the required
