Abstract

Boiler slagging and high-temperature corrosion were the most severe problems that coal-fired boilers are facing due to the widespread employment of low-NOx burners with staged combustion system. In this study, sample characterization, numerical simulation and field adjustments were used to consider the effects of coal quality and boiler air distribution on boiler slagging and high-temperature corrosion of a 1000 MW ultra supercritical double tangentially fired boiler. Characterization results verified that alkali metals compounds were responsible for boiler slagging and the boiler was suffering sulfide type corrosion. To predict the distribution of H2S in boiler, an optimized H2S reaction mechanism was introduced into numerical simulation, and the rear wall was considered to have the greatest risk of high-temperature corrosion. After determining the negative correlation between O2 and the reducing atmosphere in the boiler, three air distribution adjustment schemes were proposed and field adjustment experiments were conducted. The results showed that both the increasing of the total air volume and optimizing secondary air distribution performed a positive influence on mitigating reducing atmosphere, and the water-cooled wall peak temperature also decreased to safety limits, which provided theoretical and operational guidance for the prevention of slagging and high-temperature corrosion in boilers.
