Saves on gas

Fulton's new modulating burner uses a linkageless burner management system to operate two modulating actuators: one regulating the flow of gas; the other adjusting air flow to ensure optimum combustion across the full firing range of the boiler. Each valve can be adjusted by as little as 0.1°, allowing small adjustments to be made to output.

Gas flowing in is controlled by two fuel valves, one acting as a safety shut-off, the other as a constant pressure governor. Burner output is regulated via a pressure transducer and controller using a 4-20mA signal.

Initial results of a trial at Cardiff University show a significant reduction in gas consumption and savings on electricity too.
