Main part of the boiler
Pressure parts of boiler correspond to strength requirements according to EN 303-5.
The boiler is a steel sheet body with a tubular heat exchanger in its upper part and a burner at the bottom. The fuel
is fed by screw feeder from the fuel tank into the burner. Ceramic plates direct combustion, reduce dustiness,
reflect heat back into the burner and help to better combustion. Ash-pan is placed in the boiler section under the
burner.
Heating water outlet and inlet is located in the rear part of the boiler and is performed through the flange with the
outer thread G 1 1/2” for the inlet and the flange G 1 ½“ for the outlet. Outlet with the thread G ½” is used to install
the drain tap. On the body, there is a smoke adapter to remove flue gas to the chimney.
The boiler drum is insulated by using a harmless mineral insulation which reduces losses by sharing heat into the
surroundings. The high-quality komaxit spray is used for boiler shell colour treatment.
The boiler is made in left & right design.
