Burner control systems and methods of operating a burner

Abstract

Burner control systems and methods of operating a burner are for a large boiler such as might be used in hospitals, hotels, offices or other large commercial or domestic premises.

Description

[0001]This application claims priority to United Kingdom application serial no. 1018178.2 filed on Oct. 28, 2010, and which application is incorporated herein by reference. To the extent appropriate, a claim of priority is made to the above disclosed application.TECHNICAL FIELD[0002]This invention relates generally to burner control systems and to methods of operating a burner. The invention relates in particular, but not exclusively, to a burner for a large boiler such as might be used in hospitals, hotels, offices or other large commercial or domestic premises.BACKGROUND OF THE INVENTION[0003]A known burner control system is described in GB 2169726A which also refers to GB 2138610A. The disclosure of both those specifications is incorporated herein by reference. In that control system the flows of air and fuel are controlled by air and fuel valves respectively, and pairs of values of air and fuel valve settings are stored for varying firing rates of the burner. Those air and fuel ...

AI Technical Summary

Benefits of technology

"The invention is a burner control system that uses ambient air pressure and temperature to control the amount of air and fuel going into a burner. This system recognizes that changes in these factors can affect the airflow rate and adjusts the air and fuel valves accordingly. The system can also store pairs of air and fuel valve settings for different firing rates, allowing for quicker and more accurate control of the burner. Additionally, the system can monitor the air and fuel pressures in real-time and compare them to the stored settings, ensuring safety and efficiency. Overall, this system provides a more effective and efficient way to control the operation of a burner."

Problems solved by technology

Even so, there is inevitably a significant period of time before the feedback from the exhaust gas analyser can be used to correct the setting of the air valve and, until the correction is made, the incorrect setting is maintained.

That is disadvantageous both in respect of relatively small deviations that may be due to relatively common minor variations in conditions or in respect of less common and much bigger deviations, for example, arising from a major drop in airflow caused by a plastic bag being sucked into the air inlet of the burner and obstructing it.
