* Energy quantity is calculated according to the requirements of STR 2.01.02:2016 Projecting and Certification of Energy Performance of
Buildings, expressed for Energy Performance of Buildings Classes B and C.

* Using Ø8 wood pellets (7 % moisture and 17,5 MJ fuel heating value).
Fuel load combustion duration depends on fuel type, moisture, outside temperature, heat consumption.
4
* Permanently constant draught from the boiler has to be ensured, so it is necessary to install smoke exhauster. For control of the smoke
exhauster, frequency converter and differential pressure sensor are recommended.

4.2. Design

Boiler body (see fig. 1, 2) is welded from steel sheets, it has cavities where water is heated. Body is
covered with thermal insulation coating and decorative panels.
Pellet burner is installed in the boiler hearth door. During combustion, hot combustion products, after
passing through hearth, go up and after passing through tubular heat exchanger escape from the boiler via
flue pipe.
Helicoidal turbulizers are inserted in the tubular heat exchanger to increase heat taking and improve
efficiency. Door of the heat exchanger has a gear turning the helicoidal turbulizers, which clean and push the
sooth accumulating on pipe walls inside the boiler.
In the bottom of boiler's hearth, there is the tray for falling ash with ash removal auger, which carries the
ash onto the ash removal conveyor, moving the ash into the ash box. Ash removal conveyor with the means of
chain is held in place in the special loop installed by the flue pipe, the loop can be installed on either side of
the boiler.
In the top part of the boiler, incoming and outflowing water branch pipes as well as boiler lifting lugs are
welded.
Digital controller is used to control and optimize boiler operation, monitor temperatures and control heating
system pumps. Emergency thermostat is installed in the controller. Sensor control unit is installed in the
control box which can be hung on the side of the boiler or on the wall of boiler house.
