lower combustion chamber: a round grate, a round deflector above the grate, an elbow or retort, and a steel
chamber of the air mixer. Fuel burning (pea grade coal, pellets) in automatic mode takes place in the lower
chamber. Inside the fuel feeding retort there are holes which regulate the pressure of air needed for burning, which
prevents flames from reaching the fuel feeder during the burning process. Under the combustion chamber there is
an ash pan.
Next to the boiler, there is a fuel storage bin with a feeder screw at the bottom. The ash pan capacity is
suited to the capacity of the fuel bin, i.e. the ash pan should be filled with ash after the entire fuel from the bin has
been burnt. There is a water tank behind the fuel bin for emergency extinguishing (when pea grade coal is used as
fuel) or a place for installing a thermostatic valve (required when pellets are used as fuel) – a protective device in
case flame gets to the fuel bin.
The fan which supplies air for combustion is situated before the fuel bin
and is connected to the mixer.
The amount of air is controlled electronically by the boiler regulator.
The inlet and outlet of heating water is situated at the back part of the boiler. At the back of the boiler there
is a smoke conduit, which carries flue gas to the chimney.
The exchanger is insulated with mineral wool, which reduces heat loss during combustion. The steel
casing is protected with high quality powder paint.
3.1 Hand-fired furnace of the KLIMOSZ COMBI and KLIMOSZ COMBI B boiler
The KLIMOSZ COMBI and KLIMOSZ COMBI B boiler provides the possibility for burning solid
fuels in the traditional mode. After manual loading, wood and coal, as substitute fuel, can be burnt in the upper
part of the exchanger, called the "upper combustion chamber".
The upper combustion chamber is an emergency
chamber, in which burning throughout the heating season is not recommended due to the lower power capacity
achieved as compared to the maximum power capacity of the boiler. For burning in the upper chamber to run
properly, some conditions for chimney draught have to be met
.
