4. FUEL
The basic fuel for
- PLUS
boilers is dry firewood leafy or coniferous of
piece, the glade, chips, waste material of wood of the furniture industry in the form of blocks,
frameworks with the calorific value exceeding 12000 kJ/kg and 20% humidity (maximum
allowable 25%). When this fuel is used the manufacturer ensures the efficiency and
continuous burning specified in this manual.
Using inferior fuels, especially of higher humidity, ash content or low calorific value
can cause boiler efficiency loss and more labor-intensive boiler operation (more frequent
cleaning, loading, etc.).
Alternative fuels to be used with
- PLUS
boilers (keeping the humidity
recommended for the basic fuel) are:
- hard coal, with the heat value approx. 24000 kj/kg the diameter of grains 40-80 mm,
- brown coal, briquettes up to 40 mm,
- bark, shavings, dry twigs, sawdust, coaldust, chips (all these fuels should be
briquetted) Alternative fuels should be mixed with the basic fuel in the ration of 1 to 1.
5. DESCRIPTION OF THE - PLUS BOILER
(see the diagram of the layout of boiler components)
The boiler design ensures the performance of so called bottom burning process. All
the internal shell components are made of integrated boiler plates. The external shell is
made of welded structural sheet metals. On the outside the boiler is insulated with insulating
material and housed in a casing made of painted steel sheet. The temperature control and
fan are located on the upper boiler cover. The boiler is highly effective in burning all kind of
solid fuels because the controller and fan are installed in an integrated casing. It is very
simple to replace them in case of a failure. There is no need to disassemble any
components: it is just enough to unscrew four screws and replace the controlled with a new
or repaired one.
The boiler has a cast-iron grate made of bars. The loading chamber is separated from
convection ducts by a water compartment with a duct supplying so called secondary air to
the ceramic burner. Below the burner there is the fire bridge, which prevents burner
contamination by post-burning waste (ash, cinders) and maintains a layer of glowing embers
necessary to ignite gases generated at the first burning stage. Behind the burner there is an
after-burning chamber covered with ceramic fittings accumulating heat and improving flue
gas after-burning conditions.
