摘　　要：提出一种利用生物质气化装置加热空气对净化间采暖的方法,按传热学基本理论进行建模,推导出计算盘管出口空气温度的线性方程及计算采暖后净化间温度的非线性方程.以某生物质气化站数据为例计算盘管内径为0.08,0.10,0.12 m时满足采暖要求所需盘管长度及风速,验证了该方法的可行性.利用软件Origin对计算得出的净化间温度值进行线性拟合,求出了净化间温度与风速之间的对数函数关系式.确定了风速的设定范围,并对比了采暖能耗与采暖产热量.相比于传统的电暖气,可降低能耗95%以上.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. 08 m,0. 10 m,0. 12 m 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.
