Abstract

Abstract: Abstract:In a 350MW coalfired power plant in Brazil, the fired coal is of high ash content and large abrasion index. So the boiler heating surface abrasion and leakage faults occurred. Aiming at above problem, some measures, such as to control velocity of flue gas, to install antiabrasion devices, to adjust operation mode and so on, were adopted. The abrasion and leakage faults of the boiler were controlled effectively.

Key words: Keywords:coal grade, high ash content, abrasion index, flue gas, antiabrasion device
