Since 1980

With a Seasonal Efficiency of 97.4%* the Blue Supreme range from Firebird is the most efficient domestic oil-fired boiler in Europe. Incorporating cutting-edge German blue flame burner technology, models are available for internal, external and boilerhouse applications. The outstanding efficiency is achieved by utilising a patented Heat Recovery System in conjunction with the boilers' third heat exchanger. This pre-warms the air required for combustion, allowing more energy to be extracted from the combustion gases.

A common assumption is that Blue Flame technology has only been developed in response to pending changes in legislation, when in fact Firebird have worked in partnership with German manufacturer MHG Heiztechnik GmbH for many years. Together, they developed the first mainstream Blue Flame oil-fired condensing boiler in the UK (the Blue Supreme Range), which has been available for over three years.

The principle of Blue Flame technology is simple; heating oil is converted to a gas at high pressure, through a high tolerance nozzle (using the thermodynamic premixing principle). This is then premixed with the air required for combustion, via a special mixing system diffuser. The perfectly homogenised air/ fuel mixture is directed into the centre of the intended burning zone, prior to ignition and the flame produced is channelled down the burner tube to form an intense, elongated flame. A percentage of the hot combustion gasses produced are then re-circulated back through slots in the burner head, where a degree of integral reburning takes place. The intensity of the flame, and the recirculation process, burns off high concentrations of NOx that are usually generated in the combustion process.
