5 Boiler construction
Smart Fire boiler has been designed as compact structure. Most of the boiler parts are hidden behind
the covers which protects them against elements and mechanical damage. Smart Fire boiler, its
dimensions and placement of the connectors to the heating system and the chimney outlet have been
shown at the fig. 1. Figures 2 - 4 show the boiler specifying its main systems.
There two main elements within the Smart Fire chassis: the boiler's body and the fuel feeding
system. The body includes: a collector. a steel heat exchanger, the combustion chamber and the ash
tray chamber. Inside the steel heat exchanger you will find vertical hot gas pipes. The exchange
features a manual cleaning system. On top of the exchange rest the upper collector and the ceramic
deflector made of vermiculite. The exchanger rests on the lower part of the body which consist of:
the combustion chamber, the ash tray chamber, the exhaust collector. A ceramic burner fits inside
the combustion chamber. The burner is fit with an automatic clearing system. Fuel falls down from
the auger feeder having its outlet placed above and equipped with rotary valve. Burner's ash falls
from the combustion chamber to the ash tray in the chamber underneath. An exhaust collector is
placed behind the ash tray chamber. Exhaust of the combustion is sucked to the exhaust collector
with an outlet fan and then directed to the exhaust collar.
The other main system supplies fuel. It is integrated in the external chassis of the boiler covers.
These includes: fuel container,the auger feeder with a motoreducer and rotary valve. Fuel falls from
the main fuel container to the auger feeder. This in turn, pushes fuel into the rotary valve, which
separates the fuel located in the auger feeder from flame in the burner. When the fuel leaves the
rotary valve, it falls directly into the burner. The boiler body connects to the fuel supply system with
the collar of the auger feeder.
Two covering panels are fixed in front of the boiler. The upper panel is fixed and it is the upper part
of boiler body. You can access the combustion chamber and the ash try chamber with the pair of
inspection doors behind the bottom panel. A control display showing current status of the boiler is
fixed at the front wall of the fuel container.
The inlet and outlet of the heating system water are located at the back wall of the boiler. These are
threaded pipe ends with a 1¼ " internal thread. The back wall also holds the exhaust collar
connecting the boiler to the flue system. The exhaust collar contains exhaust gas temperature sensor.
The placement of the connectors has been detailed on the fig. 1. An outlet fan is fixed to the back
