重油气化装置“U”型管冷却器的计算与改造

The Calculation and Reformation of the U Type Tube Cooler in the Heavy Oil Gasification Unit

为寻找对“U”型管改造的理论依据 ,编制了FORTRAN计算程序 ,计算出不同条件下的水出口温度、气体出口温度和壁温 ,并据此对“U”型管进行环隙改大等项改造。

In order to seek out the theoretical basis for the reformation of U type tube, the FORTRAN calculation procedure has been compiled, the outlet temperature of water, outlet temperature of gas and the wall temperature are calculated under the different conditions, and upon these the circular gap enlargement ETC is made to modify.
