Example of Gasifying Boiler for Wood            The new series of combo boilers ATMOS DC 15EP(L), DC 18SP(L), DC 25SP(L), DC 32SP(L) facilitates the burning of wood on the principle of wood gasification in combination with a burner for pellets, natural gas, or heating oil. The boiler enables changing of fuels by just changing the burner while all existing pipework, flue and controls stay the same. The boiler can be purchased without a burner and select one later or to use a burner from the last boiler.

The boiler proper is constructed as a body of three chambers situated one above another. The two upper chambers serve for the gasification of the wood, as you are familiar with from the classical gasification boilers that we produce as the standard. In the third, lowest chamber, is installed the required burner at the front, inlaid by ceramics to ensure the optimal quality of burning. Both the systems are separated by a water jacket so that they do not interfere with each other and, thanks to this; the boiler achieves high effectiveness when heating by the individual fuels. The combustion gases exhaustion is handled by one outlet and therefore only one flue is needed.


            

  • Possible combination of the individual types of fuel -
    • fuels changing without modifications in the boiler wood + pellets, wood + natural gas, wood + heating oil.
  • Possible substitution of the individual burners -
    • at any time, it is possible to choose a different medium.
  • High effectiveness in the individual fuels -
    • for all practical purposes identical as in the special boilers for extra LFOs, natural gas, or pellets (up to 92.3% at the nominal output).
  • Cheaper solution -
    • adding the costs for the purchase of two boilers, their installation and smoking, we find that one boiler, though more expensive, is more economical.
  • Less built-up area compared to a greater number of boilers.
  • One chimney and flue .
  • Ecological operation in all the versions of heating.
