M series boilers with “volcanic” fuel supply

M series boilers are used for heating of large sized residential and industrial premises and supplying heat for technological needs. Fuel used: saw dust, wood chips. Larger pieces of wood can be burned by loading them through the combustion chamber doors.
Main characteristics of these boilers:

* for more efficient and environmentally friendlier combustion fuel humidity content should not exceed 45%

* Good economic and environmental performance

balanced water flow in the heat exchanger protects it from overheating and residue
preheated primary and secondary air is supplied into the combustion chamber
Efficient combustion is achieved by correct rate between the heat resistant concrete and heat exchanging surfaces. Primary and secondary air fans are separate
For more efficient heat exchange turbulators are mounted into tubular heat exchanger
Auger conveyor supplies fuel into the boiler which is spread in the combustion chamber
Boiler operates together with fuel storage and supply equipment
Ash is removed manually from the ash tray

Boiler controller controls

Fuel supply conveyor
Primary and secondary air fans
Boiler exhauster
Boiler recirculation pump

As an option boiler may be fitted with pneumatic heat exchanger cleaning system
