Abstract: A heating method was proposed for heating of clean room by using biomass gasification device to heat air. Calculation model was built by heat transfer theory， linear equation to calculate temperature of coil outlet air and non-linear equation to calculate temperature of clean room after heating were deduced. Under condition of some biomass gasification station with 0.08m， 0.10m， 0.12m coil inner diameter， required coil length and wind speed fitting for heating were calculated. Then feasibility of this method was verified. The “Origin” software was used to make linear fitting for calculated temperature of clean room. Logarithmic function relation of clean room temperature and wind speed was determined. Then range of wind speed was confirmed， and the heating energy consumption and quantity of heat production were compared. Be compared with traditional electric heating， it could reduce energy consumption for 95% and more.
