Fig. no. 2b) Main parts of boiler
The pressure parts of boiler correspond to the strength requirements according to:
EN 303-5
Heating boilers – Part 5: Heating boilers for solid fuele, hand and automatically stocked, nominal
heat output of up to 300 kW – Terminology, requirements, testing and marking
The cast iron body positioned on the basement welded of steel sheets is the core part of the boiler. The boiler
drum consists of sections connected by means of pressed-on boiler inserts of 56 mm diameter and secured
by anchor bolts. The sections form the combustion space, water space and convective part. Heating water
inlet and outlet are situated at the rear of the boiler by means of two flanges 2” for connection to the heating
system. The temafast Ø 60 x 48 x 2 mm sealing is between the boiler and flange.
The rear boiler section has the smoke adapter and heating water flange in the upper part and the return water
flange is in the lower part of the basement. The cleaning door and ash-pan door are fastened to the front
section. The folding grate is positioned behind the cleaning door (6).
Under the cast iron body there is positioned the burner with mixer (see. Fig. no. 3) that consists of cast iron
grate and retort. We use 4 types of cast-iron grates with regard to the size of the boiler and fuel used. The
various types of grates are marked with an identification symbol, see Figure 3 - a detail In table No. 5 there is
shown the assignment of individual types of grates to a given boiler and fuel type..
The fuel is fed from the reservoir through the feed screw emptying into retort on the cast iron grate.
The ash-pan drawer is under the combustion chamber. Next to the boiler there is positioned the fuel reservoir
that empties into fuel feed screw.
Ventilator for combustion air is positioned behind the fuel reservoir and is connected to the burner. Ventilator
has the modulation control by SAPHIR regulator depending on the required output.
All components (boiler drum, basement) are insulated by means of health non-detrimental mineral insulation
that reduces the heat transmission losses.
The high-quality komaxit spray is used for boiler shell colour treatment.
The boiler is made in left & right design.
