Wood-fired Boiler
Vitoflex 300-UF 390, 530, 720, 950 and 1250
Vitoflex 300-UF with an attached external grate and a
moving annealing grate to achieve optimal combustion
results.
A feed auger continuously moves the wood fuel onto
the burner trough where gasification takes place.
The combustible gases blend with precisely controlled
secondary air, resulting in a complete combustion and
the thermal energy is released into the boiler’s triple-pass
heat exchanger.
