Magno-SR 700

The Magno-SR is an industrial biomass boiler built for continuous high-performance operation, using step grate (SR) technology for wood chips, fine wood shavings, bark and other biomass fuels with high moisture content, up to 60% (wood chips up to M60/W60). A hydraulically driven forward-moving step grate handles drying, gasification and combustion of the fuel, with automatic ash removal at the end of the grate to reduce maintenance requirements. The design combines a solid radiation vault with high-temperature resistant refractory bricks, a dual-walled steel housing that preheats the combustion air, integrated exhaust gas recirculation and automatic pneumatic heat exchanger cleaning. Combustion is controlled via flue gas, combustion chamber, boiler temperature and Lambda sensors, allowing modulating operation and an efficiency of up to 93%. Target applications range from hotels and restaurants to district heating schemes and large commercial and industrial enterprises.
