Premix packaged burner range extended

09 April 2018

Building on its RX range of premix packaged burners that have outputs to 1500kW, Riello has extended the offering with variants up to a 3MW model, whilst still achieving NOx levels of less than 30mg/kWh and low noise output.

In RX premix burners, the gas and combustion air are mixed upstream of the combustion head. The mixture then passes through precision-located ports and a patented gauze ‘sock’ to ignite on the external surface of the combustion head. The result is a compact flame with a diameter directly related to the burner firing rate, ensuring precise heat control and optimum efficiency at all loads.

Riello premix technology enables high turndown ratios of up to 8:1, making RX burners suitable for systems with variable heat loads – from condensing boilers through to process applications such as spray booths and industrial ovens.

RX burners can be used in conjunction with variable speed drive motors to reduce electricity consumption and lower noise levels. Control options include progressive two-stage operation and fully modulating via 0-10V or 4-20mA. Full electronic control with operational and diagnostic display is also available.
