Boiler control methods

摘要

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.

1. A method for controlling a boiler configured to provide a heated boiler fluid for heating a space of a building that is to be temperature controlled by the boiler, wherein the boiler including a burner, the method comprising:
receiving a call for heat that is based on an air temperature sensed in the space of the building; firing the burner based on the call for heat; with the burner firing, monitoring over time a temperature deviation between a temperature of the boiler fluid of the boiler and a heating temperature profile, and if the temperature deviation exceeds an allowable deviation, shutting off the burner; and wherein the heating temperature profile represents an expected temperature response of the temperature of the boiler fluid over time to the burner firing; and subsequent to shutting off the burner, monitoring the temperature of the boiler fluid over time.
