Feasibility analysis of 700MW supercritical boiler induced draft fan renovation

Abstract

Abstract:

The power consumption of No.5 boiler induced draft fan of a 700MW supercritical unit in a power plant is relatively large.When the opening of the induced draft fan reaches 60%, and keeps increasing under heavy load, the current growth rate will be too fast; and the operating oxygen of the boiler cannot meet the targeted value. A thermal test on the No.5 boiler induced draft fan was carried out, and combined with the condition of the flue gas system resistance, the feasibility of reducing the blade of No.5 boiler induced draft fan rotor is analyzed. It provides data support for No.5 boiler induced draft fan renovation.

Key words:

induced draft fan, rotor, thermal test, performance curve, energy saving
