Messersmith combustion systems are designed to efficiently burn a variety of wood based fuels with moisture content up to 50%. The Messersmith combustion chamber contains a set of sloping grates, with no moving parts to jam or wear out. Fuel delivered from the Stoker Augers moves down the sloping grate system as it burns. Underfire combustion air is delivered to the fuel through small holes in the grates. Overfire combustion air is delivered above the fuel through nozzles built into the refractory lined sides of the combustor.
Both underfire and overfire combustion air are pre-heated and then modulated by the Control Panel to always match the amount of fuel delivered to the Combustor. In this way, we maintain a highly efficient and clean combustion. Combustion efficiency is typically greater than 99%.
