3.2 ADVANTAGES
- Steel offers numerous advantages, which are of a particular importance
for the modern heating technique. Among these we mention the special
mechanical quality, remarkable formation possibilities, smooth surfaces and low
weight.
- a great advantage of THERMOSTAHL boilers is the great water
capacity, which allows the precise adjustment of its temperature and no
exceptional requirements concerning the water outflow. The interior energy of the
boiler contributes considerably to the protection of the enviroment, because the
great volume of water increases the storage capacity of energy, and reducing the
number of ignition starts of the burner (in case of adapting of a burner)
- Reliability .
- Energy savings.
- Enviromental friendly.
- Modern Design.
- Solid Construcţion
- Easy maintenance
- Big fire box.
- Large heating surface.
- High performance ≥ 78 ÷ 82%.
- Uniformal thermal charge.
- Low outlet of burned gases (180 -220oC).
- Long life without problems.
- Exceptional draught.
- High water volume.
- Possibility of working also with gas or liquid fuels
3.3 RUNING ORDER
It is based on the radiation generated by the flame in the combustion chamber and the
heat transmision by transfer and conductibility through the fire tubes (exhaust pipes).
The runing of the MULTIPLEX boilers is based on the most simple method of burning,
with free evacuation of the exhausts through the chimney. The burning proces takes place in
the combustion chamber, built in such a way that there may fit woods of long dimensions and
in quantities capable to maintain the operation for several hours. During the burning process
the flame develops twards all the points and heats the boiler walls who are cooled by water.
Later on, the exhausts are led through the smoke pipes from which they go to the
smoke box. The remains of the burning fall in the lower section of the boiler where there is an
ash tray specially designed for that.
