Abstract

Combustion modifications to minimize NOX emissions have magnified the importance of waterwall corrosion in coal‐fired boilers. The physics and chemistry controlling corrosion processes can be highly non‐linear and are challenging to describe in terms of their likely overall combustion behavior. This paper describes the application of a multi‐point, real time corrosion surveillance system to a large boiler firing high sulfur coal. This technology, incorporating electrochemical sensing and wireless signal transmission, enables combustion engineers and plant operating personnel to make informed decisions regarding the quantitative relationships between operating conditions, NOX emissions, and any resultant extent/magnitude of waterwall corrosion.
