The new DR SE FGR burner platform represents the evolution in Riello Burners industrial product range for high power applications. They are dual block burners for applications in in big civil heating plants (i.e. hospitals, district heating) and industrial processes (i.e. food chemicals, textile industry) with a remarkable thermal demand. They can be
matched with hot water boilers, steam and thermal oil generators. These burners allow to realise a modular and flexible combustion system adding a preparation fuel unit, a gas train, a control panel and a fan. Control panel with high-end control box can be supplied installed on burner board. These burners are supplied with electronic air-fuel ratio control in order to obtain a perfect output control and to assure a correct low polluting combustion and a safe operation on all modulation range. Preheated air can also be used as in the oil diathermic generators and other heat recovery systems. The modulating regulation always allows to reach a wide modulation ratio and optimal fluid-dynamics conditions for a good combustion. The low-NOx combustion head allows to reach, on natural gas operations, NOx emissions ≤ 80 mg/kWh without FGR use (≤ 50 mg/kWh with 10% FGR).
