Most of you already have some experience in using wood or wooden briquettes for heating either in boilers or fireplaces. These fuels are widely available at reasonably good prices. A new product, not yet known by all, is the so-called pellets, which are produced in a similar way as wooden briquettes by high-pressure pressing of waste wood (dry sawdust and chips) without any binder. It is predicted that in the near future the same production technology shall be used to produce pellets from straw and various biological wastes. The most frequently used pellet size is with a diameter of 6, 8 and 9 mm and a length of 5 to 25 mm. The heating value is approximately the same as for wooden briquettes, ranging from 17 to 19 MJ/kg. The price of pellets is in Czech Republic 85,- to 130,- GBP per ton. Pellets are supplied in PVC bags (usually 15, 20 or 25 kg). In Germany or Austria the pellets are delivered in cistern trucks from which suppliers fill any type of tank, as in the case of LTO (light fuel oil). It is very important to store pellets in a dry place to prevent their deterioration.
Our company has designed D15P (4,5 kW - 15 kW output), D20P (6kW - 22 kW output), D30P (9kW – 30kW output) and D45P (13kW – 45kW output) and combo boiler for wood and pellets DC15EP, DC18SP, DC25SP, DC32SP (6kW - 35kW output).
Boilers are designed in such a way that the IWABO or ATMOS ERATO GP20 or ATMOS A50 BeQuem or ATMOS A70 Petro burner is built into the left or right side of the boiler, functioning as a heat exchanger, which draws pellets from the storage tank by means of a screw conveyor. The fuel tank is located next to the boiler or in an adjacent room and can be of any arbitrary size (the standard size is 250, 500 l or 1000l). For conveying pellets from farther distance you can use pneumatic conveyor which we offer as well.
The burner itself functions as follows. If the burner is triggered (the need to heat arises), the conveyor pours pellets into the burners spout and ignites them using a glowing coil. Following sufficient pellet combustion, the burner is adjusted to the set output where it remains until the system is heated. Thereafter, the burner is switched off and pellets in the burners chamber are burnt out. The whole cycle is repeated again when heating is required. The boiler output and other burner functions are controlled electronically, which enables an adaptation of the boiler operation to specific system conditions. Addition of fuel, cleaning of the burner combustion chamber and removal of ash is performed once every 1 - 30 days, depending on the quality of pellets. A great advantage of our pellet boilers is that the burner is removed from the boiler and replaced by a lid, and wood can be used to heat the system. These features mean that these boilers offer the same degree of operating comfort and utility value, as do boilers running on gas, propane-butane or LTO. The main advantage is that in comparison with natural gas or LTO, these boilers combust renewable energy sources, which makes their prospects look very good.
