Application of programmable controllers to oil fired boiler light-off system

Technical Report ·
OSTI ID:6494623
A programmable controller has been used to improve the reliability of an oil-fired boiler burner control system. An outdated and failing Germanium discrete transistor logic control system was replaced with a modern solid state large scale integrated circuit programmable controller. The ease of making this conversion at a modest expenditure during a limited boiler outage is explained, as well as pitfalls and problems encountered. Light-off reliability with fuel savings were prime objectives. The boiler, rated at 575,000 lb/hr at 450 psig, is used as a backup steam supply for the dual purpose N Reactor at Hanford, Washington, which supplies 860 MWe to the Bonneville Power Administration and weapons grade Plutonium for the Department of Energy. High reliability in light-off and load ascension from standby is required of the boiler which serves as the backup power supply for the reactor.
