Fulton has introduced an energy-saving modulating burner, which is suitable for use with gas-fired vertical boilers.

Based on the company’s existing on/off burner, the new product uses a linkage-less burner management system to operate two modulating actuators.

One actuator regulates the flow of gas and the other adjusts air flow to ensure that optimum combustion is possible across the full firing range of the boiler.

To optimise combustion, each of the valves is capable of being adjusted by as little as 0.1, allowing small adjustments to be made to the burner output.

Gas flow into the burner is also controlled by two fuel valves, the first acting as a safety shut-off and the second being a constant pressure governor.

Burner output is also regulated via a pressure transducer and controller, which uses a 4-20mA signal to modulate the burner output.

The new modulating burner is available as an option on all gas-fired vertical boilers in Fulton’s range, including the J Series and the new VMP multi-port tubeless steam boiler.

It can also be retrofitted to pre-installed boilers.

Initial results from a three-month trial at Cardiff University where two Fulton 60J boilers are installed – one using a standard on/off burner the other a new modulating burner – indicate a reduction in gas consumption, with further savings being made on electricity.

Thanks to the burner’s modulation, the boiler is also more efficient as the steam pressure is kept at a more consistent rate.

The Fulton name has been synonymous with steam since the company first introduced the vertical tubeless steam boiler in 1949 and Fulton was established in Bristol in 1966. Fulton is still one of the world’s leading manufacturers, producing an unrivalled range of multi-fuel steam boilers. But increasingly these are ordered by customers as part of bespoke turnkey systems designed to meet exacting specifications.

Today Fulton Ltd is an important design and manufacturing base in Fulton’s global network that also includes production facilities in the US and China. The company’s UK facility makes it possible to manufacture products more efficiently and to assemble completed units for whenever and wherever they are needed throughout the UK and in export markets.

Once just a steam boiler manufacturer, Fulton now specialises in ready-to-ship skid-mounted and fully packaged boiler plant rooms to meet the current demand for off-site fabrication. The company puts great emphasis on providing sales and application advice and a full commissioning and after-sales service to a growing customer base in hospital and healthcare facilities, food and beverage processing, laundries and other applications.

Design and manufacturing resources are shared and co-ordinated around the world, but no matter where your product originates it will always be produced to the highest quality in a facility that is wholly owned and managed by the Fulton Group, which remains a privately owned family business.

Fulton’s heating and hot-water systems can be delivered as fully prefabricated plant rooms or complete skid-mounted units, built to fit a prepared location and to connect direct to your services.

Using the latest CAD equipment, its design team can accommodate the most sophisticated engineering specifications in surprisingly compact spaces, locating components in the best possible position to suit the installation.

In every sense, today’s Fulton boiler systems are solutions that fit the requirements of the modern age of steam.
