Fire Plus System
The Fire Plus System of your FIREPLACE provides optimal, environmentally
friendly burning and - combined with an effective heat exchange system - high
efficiency.
After loading and lighting the fuel, the first phase of the combustion process
starts by proceeding to burn the gases leaving the fuel. This is the time of, "high
flames". After the flames reduce, the rest of the coal burns up in the second
phase of the combustion process. This process is characterized by strongly
glowing embers with no or only smaller, temporary flames.
Optimal and environmental friendly burning with high efficiency can only be
achieved if we provide the necessary quantity of air at the appropriate places
in all phases of the combustion process. Both the longer time spent in the com-
bustion chamber by gases mixed with air and the hot combustion chamber
have a positive effect on the combustion process.
This effective burning can be achieved by the Fire Plus System. The primary air
flow through the openings of the grate is completed by the secondary air flow
through the glass front and tertiary air entering at different heights of the com-
bustion chamber.
Wood, wooden briquettes and brown coal briquettes are fuels of "high flame".
At this height and later above the glowing embers secondary and tertiary air get
inside in such way that mixing of the air and gases and the time that gases
spend in the combustion chamber (depending on their structure) results in good
burning. The excellent quality lining (chamotte, vermiculite) of the combustion
chamber, provides high temperature, helping the process.
After, that gases are lead through one or more dead-plates in the upper part of
the stove, namely through a heat exchange system, that consist of a pipe sys-
tem where heat is transmitted again.
Gases finally leave the stove through the flue outlet and then enter the chimney
at a temperature of 230-300°C through the connecting pipe. The remaining
energy content of the gases provides the necessary feed pressure in the chim-
ney, "motor of the stove".
This is the operating principle of FIREPLACE stoves.
Fireplaces are structurally not suitable for non-stop use.. Only a relatively small
amount of fuel can be loaded in the combustion chamber at any time. More
information about quantities of fuels loadable for one occasion is given on the
attached technical data sheet.
