Application of PLC/PC based sootblower/waterlance control systems for optimizing boiler cleaning
- Detroit Edison, MI (United States)
This paper concerns retrofitting and upgrading existing sootblowers and waterlance control systems with a Programmable Logic Controller (PLC) and Personal Computer (PC)-based control system. The PLC is used for front end data collection and processing, and the PC is used for operator interface, sequence control and data acquisition for optimizing sootblower and waterlance performance. The versatility of the PLC/PC based control system provides a number of options to optimize boiler cleaning. Efficient and reliable boiler cleaning has been and continues to be a requirement due to the use of various types of coal required to meet various environmental requirements, while maintaining proper heat transfer. This paper will discuss a Boiler Cleaning Control System (BCCS) incorporated at the St. Clair Power Plant in April 1994. Provisions were made as needed for future interface to a Distributed Control System (DCS) and for boiler cleaning based on boiler performance, e.g., steam temperature.
