Optimization of condenser tube bundle arrangement pattern and its application effect analysis

Abstract

Abstract:

In order to solve the substandard pressure problem of a condenser for coalfired power plant, this paper proposed a new bionic tube bundle arrangement pattern for the condenser, and replaced the copper tubes with stainless steel tubes. The system commissioning test shows that after the optimization of condenser tube bundle arrangement pattern, the condenser pressure decreases by 0.88kPa, the supercooling degree is less than 0.5℃, the condenser thermal performance is improved greatly, the eddy and air accumulation phenomena are not found in the main condensation region, and the unit could save standard coal 2.64g/(kW·h), which has a good economic benefits and environment protection benefits.

Key words:
