供热机组低真空单、双转子改造的经济性分析

摘要

The low vacuum heating retrofitting of heating supply units has two ways: single rotor and double rotors which would be replaced each other.The backwater temperature of heating network has affect on the selection of low vacuum heating retrofitting schemes.This article calculates the economy of the two kinds of retrofitting scheme.And during heating period the two kinds of retrofittings have the different back-pressure.It provides the theorotic guidance for the scope of application of the single,double rotor retrofit scheme.%供热机组的低真空改造有两种方式:单转子和双转子互换方案,而热网水回水温度影响了低真空改造方案的选择.在供暖期背压不一致的情况下,对两种改造方案进行了全年收益的经济性计算,从经济收益上为单、双转子改造方案的应用范围提供指导.
