1. TECHNICAL SPECIFICATIONS
The fireplace stove is designed for heating in habitable rooms, recreational buildings, work
stations and other places to provide thermal comfort, while the visual effect – the
perception connected with flame – is similar to the sensation of live fire.
1.1. Heating concept
The fireplace stove is designed for burning wood, eco-fuel cakes and coal cakes (specific
types only) in a burning-through way, characteristic with very good firing conditions.
The air within the room is heated thus the thermal comfort is provided by heat convection,
in part by heat radiation as well. This way, you can heat up even very cold, long-time
unheated rooms very quickly. The concept of heating by means of heat convection is based
on the fact that the air in the room enters the fireplace stove at its bottom part, being heated
in the course of its way up inside the convection space consisting of a double shell of the
heating device. The air then flows through the holes in the upper part of the fireplace stove
back in the room. The radiation heat is generated by means of surface areas of the
fireplace stove (metal, ceramics, glass). Due to the construction, the biggest radiation heat
source is the glass door.
1.2. Construction design
The fireplace stove is welded of steel profiles, thickness 2-5 mm. In the middle of the
fireplace stove, there is a firing chamber that may be closed with a stocking door (equipped
with a self-acting element). The door is provided with special a large-area glass sheet,
thermal resistance up to 800 °C.
The inner space of the firing chamber is usually lined with fireclay brick shapes. The bricks
are not jointed with any filler (the reason is a protection of the bricks against damage by
thermic dilatation). The upper part of the firing chamber is equipped with partitions
designed for directing flue gases into a smoke outlet. The partitions may be fixed or
movable. Such movable partition may serve as a supporting holder for fireclay bricks. At
the bottom part of the firing chamber, a simple, fixed cast grate is installed. Before the
grate, a barrier is usually provided, to prevent from burning pieces falling out or onto the
door (front glass). Under the grate, there is a space designed for ashpan. The remaining
space at the bottom part of the fireplace stove may be used for spare fuel.
Fireplace stove casing is made of steel panels, ceramic tiles or lined of thick tiles. The
fireplace stove steel construction is protected with special refractory paint.
Caution! The fireplace stove is not designed for continuous heating but for
periodical – interrupted (i.e. temporary) operation.
