Scheme Design and Analysis of Variable Condition of Evaporative Condenser for Steam Condensing of Steam Feeding Water Pump for 1000MW Air-cooled Unit

摘要

Evaporative condenser for steam condensing of mini-turbine of steam feeding water pump for 1000 MW air-cooled unit is designed. Variable working condition is analyzed based on the reverse flow between steam and air. The results show that the condensing temperature of the steam in the tube increases with the air temperature and water film temperature increasing. The condensing temperature of the steam decreases with the water flow rate increasing and the wind velocity increasing. The evaporation capacity of the water outside the tube increases with wind velocity increasing. This paper can be refered when evaporation condenser is applied in thermal power plant.
