Analysis of Heat Dissipation and the Energy Conservation in Cast Iron Dryer Head of Paper Machine

Abstract

Analyzed the result computed of finite element heat transfer, discovered the temperature difference between the two sides of head is very small. Therefore its hot loss is very big. In addition, the temperature of dryer head flank is basically the same. Therefore the dryer head's heat dissipation can be simplified as a question of univariate heat conduction, also simplified to be a big plate heat conduction problem. This article offers simple algorithmic analysis of dryer head temperature field algorithm and the heat dissipation computation, and studied the head temperature computation and the heat dissipation analysis with a heat preservation board added. The importance that increased heat preservation board for energy conservation is pointed out.
