| Abstract: | On the basis of the First Thermodynamics Law, using heat transfer theory, the impact of fouling thickness on condenser vacuum, unit power and unit heat consumption rate is calculated by quantitative analysis method when duplex pressure condenser cooling water tube is fouled. The calculation result indicates that cooling water tube fouling has an obvious influence on condenser vacuum and operation economiy of power unit. The result of the research has an important current significance for improving utility-type unit economical operation in power plant equipped with duplex pressure condenser. |
