Abstract
A method for controlling a boiler includes firing a boiler, and monitoring a temperature deviation between a boiler temperature and a heating temperature profile over time. If the temperature deviation exceeds an allowable deviation, the boiler is shut off.
Claims20
A method for controlling a boiler, comprising:
- firing a boiler;
- and
- monitoring over time a temperature deviation between a boiler temperature and a heating temperature profile, and if the temperature deviation exceeds an allowable deviation, shutting off the boiler.
A method for controlling a boiler, comprising:
- firing a boiler;
- and
- monitoring over time a temperature difference between a first boiler temperature and a second boiler temperature, the first and second boiler temperatures being monitored by sensors at different boiler locations, and if the temperature difference exceeds a selected difference, shutting off the boiler.
A boiler system, comprising:
- a boiler;
- a sensor for sensing a boiler temperature of the boiler;
- and
- a controller for controlling firing of the boiler, the controller configured to compare over time the boiler temperature with a heating temperature profile, and to shut off the boiler if a temperature deviation between the boiler temperature and the heating temperature profile exceeds an allowable deviation.
