With many years of experience in the design and manufacture of burners, Riello has developed a new range of industrial products; the new HTDR gas burner series with high turndown ratio (up to 58:1) dedicated to process applications.

The light and compact burner structure is made in carbon steel; the elements in direct contact with the flame are manufactured with highly resistant materials, such as refractory steel and nickelchrome alloys.

HTDR configuration includes the combustion head and the components necessary for proper operation, consisting of: gas train, air fan, gas modulator, control panel and pressure switches. The control panel is available in two different versions: standard and upgraded. The standard control panel is designed for applications requiring a more compact overall structure with a multi-burner configuration (i.e. textile stenters), while the upgraded control panel version can be supplied in case of processes needing completely independent burners (as generally required by ceramic industry).

Other burner configurations (including different component displacement and/or orientation) are available on demand.

Burner operation can be on on-off, high-low flame and modulating (gas only or air and gas) with the installation of a PID logic regulator and respective probes. With modulating operation, a turndown ratio up to 58:1 can be achieved with neutral combustion chamber.

Main features:

-5 burner models, with max burner output between 750 and 3500 MBtu/h

-High turndown ratio (up to 58:1)

-Highly resistant structure

-Natural gas and LPG operation

-Wide range of application (both direct and indirect heat exchange)

Main applications:

-Textile (stenters, dryers, polymerisers)

-Ceramic (roller/tunnel dryers)

-Agriculture (fodder dryers, grain dryers, tobacco dryers, ...)

-Food (cereal dryers, roasters)

-Coating and printing industry (air heaters, dryers)

-Industrial cloth washing

-Automotive industry

-Building materials industry
