The pellets must comply with the requirements of the standard ČSN EN 14961-2.
4. Boiler description
The design of BENEKOV S boilers meets the requirements of:
ČSN EN 303-5: 2013 - Heating boilers - Part 5: Heating boilers for solid fuels, hand and automatically
stocked, nominal heat output of up to 500 kW - Terminology, requirements,
testing and marking.
4.1. Boiler design
The main part of the boiler, based on a fuel understoking design, is the boiler body that is welded from
steel boiler plates. All parts of the boiler body at the interface of flue gases and heating water are
made of sheet metal with a thickness of 5 mm. In front of the boiler body there is a combustion
chamber with a burner; at the back of the boiler body there is a 3-draft multi-plate heat exchanger
providing the decisive transfer of heat from flue gases to the boiler water. The finned heat exchanger
is fitted with an automatic cleaner, which during operation of the boiler continuously cleans the heat
exchange surfaces.
The burner, based on a fuel understoking design, consists of a screw fuel feeder and a steel grate.
The fuel feeder consists of a trough for fuel supply, a channel for supplying combustion air and a
flexible interconnection that serves for pressure equalization under the fireplace and which prevents
smoke penetration into the fuel tank during the combustion process. The burner is fitted with a ceramic
reflector that directs the exhaust gas flow, reduces fly dust and thus facilitates complete combustion.
Under the combustion chamber there is an ash drawer and shaped bed for the eventual installation of
an ash remover.
Beside the boiler there is a screw feeder that transports fuel from the external container to the burner.
The feeder consists of two screw conveyors (feeding from the bunker + feeding into the boiler) with a
turnstile between them. This serves to create an air gap between the two screw conveyors and avoids
any ignition of fuel in the container. In addition, the cover of the feeder from the bunker that transports
fuel above the turnstile is fitted with an emergency fire extinguishing system.
Depending on the position of the fuel feed screw towards the boiler drum, the boiler is manufactured in
two versions:
Right version - the fuel feeder is on the right of the boiler body when viewed from the front
Left version - the fuel feeder is on the left of the boiler body when viewed from the front
Furthermore, according to the design of your boiler room, you can select three mounting positions for
feeding from the bunker to the boiler. A side design (see fig. No. 5 and 8), front design (see fig. No. 6
and 9) and rear design (see Fig. 7 and 10).
