Customer case:

Korea Electric Power Corporation Research Institute develops combustion optimization with Valmet Boiler Diagnostics Systems

Valmet has supplied boiler diagnostics system to Korea Electric Power Corporation (KEPCO) Research Institute in South Korea. The delivery consists of four Valmet Furnace IR Camera Imaging systems with slag indexing software, which are installed in KEPCO’s Coal power boiler. As a type of combustion-related key variable, KEPCO Research Institute uses Slag Index data calculated from the Furnace IR Imaging Camera System for research and development of combustion optimization.

Furnace slag index data
Summary
Location Korea Electric Power Corporation (KEPCO) Research Institute in South Korea
Solution

Four sets of Valmet Furnace IR Imaging Camera Systems with a slag indexing software package. The camera system provides superior image quality, enabling comprehensive observation and analysis of combustion processes. 

The Slag Indexing delivers real-time views of slag conditions in critical boiler areas. From tube walls to pendants and the superheater entrance, Slag Indexing determines the ratio of a clean condition to a slagged condition. This condition ratio is then sent as an independent or added signal to the boiler cleaning controls to enable more effective cleaning of the boiler areas. 

The real-time ability to identify problems and apply solutions results in increased boiler availability, reduced risk of failure, improved heat transfer efficiency, and lower maintenance cost
