Riello extends its RX premix packaged burner range

Riello, premix, burner

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

Unlike traditional pressure jet burners, 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 the patented gauze ‘sock’ to ignite on the external surface of the combustion head. The result is a very compact flame ensuring precise heat control and optimum efficiency at all loads.

Riello premix technology enables turndown ratios of up to 8:1, making RX burners ideal for systems with variable heat loads, from condensing boilers through to process applications.

RX burners can be used with VSD motors to reduce electricity consumption and lower noise levels even further than the typical 30% noise reduction compared to many other combustion applications. Control options include progressive two-stage operation and fully modulating via 0-10V or 4-20 mA. Full electronic control with operational and diagnostic display is also available.
