Boiler body
Boiler body consists of cylindrical shaped shell, two bottoms, flame tube with cooled turned chamber
and two bundles of fire tubes that create a convection heating surface. The front turned chamber is
located in boiler cover. The gas-proof boiler cover consists of tilting door with flange for burner fixing.
The door is covered by fire resistant insulation with integrated observation window. The door is tilted
to the armature part installed on boiler sidewall. On the customer request can be boiler delivered in
left, or right variety. The boiler body is completely insulated by double insulation with metal casing.
The boiler insulation parts are supplied separately in disposable package for easier boiler
transportation.
All heating surfaces are easily accessible for cleaning after boiler opening. This assures permanent
high boiler efficiency even in case of long-term liquid fuel firing.
Boiler efficiency and flue gases temperature
Efficiency at nominal output is 91%. Flue gases temperature at nominal output is 190 - 205 °C.
