# 节流圈位置对蒸汽干燥器工作性能的影响研究 The Numerical Study of the Throttle Coil Location Effects on Steam Dryer Working Performance

This paper investigates the flow field of a steam dryer and the effects of throttle coil location on dryer working performance. The results show that the ratio of superheated steam to saturated steam is the key factor. As the steam consumption of downstream users decreases, the outlet superheat degree increases. There is a critical value of downstream users steam consumption, when the consumption is lower than critical value, the superheat degree is zero. For the various flow pattern in the various simulated conditions of this paper, the distance between throttle coil and superheat steam pipe centerline is increased from 40 mm to 300 mm, and the critical value of consumption increases by 21.23%.
