Steam boiler RL Low NOx series

electricfire tubehorizontal

Designed to work with any common fuel (Natural Gas, LPG, Diesel, Fuel Oil, Biogas) + Low voltage electric steam production (400 or 690 V), through special high temperature electrical resistances. Being able to generate steam through fuel or electricity or both at the same time. It allows responsible use of energy, being able to use electricity or fuel depending on the need, adjusting the % of each of the fuels. High head of steam, achieved thanks to the large volume and height of the steam chamber. The emissions of the boiler plus burner set developed by the ATTSU R+D+i department in collaboration with the most important burner manufacturers, make it comply with EU Directive 2015/2193 in relation to NOx <100 emissions. mg/Nm3, reaching values below 80 mg/Nm3. Great accessibility for maintenance thanks to its hinged doors. The fireplace and tubular plate are fully accessed from the front, and the rear tubular plate and gas inversion box are accessed from the rear. RLE - HYBRID boilers are pressurized combustion, with 3 smoke passages, horizontal cylindrical type, completely water-cooled. The tube bundle is equipped with turboprops that create a turbulent gas regime, thus increasing the heat transfer coefficient by convection. At the exit of the tubular bundle, the gases are collected in the rear chamber and channeled towards the chimney. A careful study of geometries allows us to obtain an optimal relationship between combustion volumes and exchange surfaces. The selection of materials and equipment is also conceived to offer the maximum longevity of our boilers.
