-The WM F is a three passes water tube boiler for hot water production, designed specifically for solid fuels, with special tube structure.
-A solid fuel boiler with a fixed grate, ideal for burning biomass and raw wood processing products. Specific fuel supply solutions and grilles ensure a constant fuel supply even when using coarse materials and compliance with current emission standards. The lineup consists of 15 models with useful heat output from 130 kW to 4,100 kW.
-Standard design pressure - 3 bar.
-Screw feed system, the result of a design combining a boiler and a mechanical burner.
-The under-grate space is divided into sealed compartments for a differentiated supply of combustion air.
-Large combustion chamber with smoke chamber and reversible flue gas flow for optimal combustion.
-Combustion takes place in two stages, the formation of combustible wood gas occurs on the grate, the flow rate of the primary and secondary combustion air in the grate is regulated in a wide range depending on the properties of the fuel used. Secondary air is supplied through an independent high turbulence system.
-High-quality mixed cast and brick refractory cladding according to the zone, tube bundle and shape of flue gas path guarantees minimum cleaning operations and complete accessibility through the side doors.
-Thermostatic system for automatically moving auger and additional fire safety device.
-High efficiency, usually exceeding 90% (mod. 130 ÷ 950) and 85% (mod. 1300 ÷ 4100).
