Air transport elements visible on the photos are not standard equipment of the furnace.
Characteristics
- Bottom combustion chamber. Furnace chamber and burner are lined with a ceramic lining.
- Fuel – wood in pieces and sawdust as well other waste material. Dust and really small sawdust is to be soaked to the humidity of approx. 30% and mixed with wood in pieces in the ratio 2 to 1.
- Air for heating the room is taken from the hall's bottom part, pressed by a furnace exchanger and then distributed with air transporting channels – ITP.
- There is a possibility to install the furnace within a set of dust collector filters and to heat up the air which returns to the hall.
Version of a Robust furnace of type A
The furnaces are manufactured in the following sizes: 50 kW, 100 kW, 150 kW, 200 kW, 250 kW, 350 kW, 500 kW and marked as furnaces of the following types:
A-51, A-101, A-151, A-201, A-251, A-351, A-501
Version furnace with fuel tank:
A-51Z, A-101Z, A-151Z, A-201Z, A-251Z, A-351Z, A-501Z
Advantages
- Heat felt from the moment of furnace activation,
- Great economy of heating costs in comparison with other solutions,
- No central heating installation or losses in conveying of hot air,
- Compact, module, modern construction,
- Simple operation and high efficiency,
- Long life cycle of the device,
- No corroding factor within the exchanger and installation,
- Chimney draught forced by the turbine allows for locating the furnace in any part of the hall without the need to build a high chimney,
- In summer period the furnace may serve as an air-conditioner,
- The furnace does not require a specialist room (boiler room),
- No obligation of carrying out of specialist tests – UDT.
Operation
The furnace operation is fully automatic. It is limited only to the process of fuel loading. This operation is carried out manually but the device is constructed so that it could make use of the production waste material as the fuel (mixture of wet sawdust, wood in pieces, edgings or bark).
