COMBINED BOILERS FOR GASIFYING - WOOD, EXTRA LFOs AND PELLETS

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 generator gasification in combination with a burner for pellets, or extra LFOs. The boiler enables changing of fuels; we heat by pellets or extra LFOs depending on which burner is built into the boiler. If needed, there is naturally the option to buy a boiler without a burner and select one later or to use a burner from the last boiler.

Boiler Construction

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 that, 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.

ADVANTAGES OF ATMOS BOILERS

  • Possible combination of the individual types of fuel - fuels changing without modifications in the boiler wood + pellets, wood + extra LFOs
  • 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, 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

Regulation

The operation of the boiler is fully automatic to heat up water to required temperature with high efficiency and in a good quality of burning. All this ensure:

  • HONEYWELL thrust regulator
  • Regulation thermostat
  • Combustion gases thermostat
  • Thermostat for a pump
  • Switch

Elektromechanická regulace je optimálním řešením řízení provozu kotle ( ventilátoru ) jednoduchým způsobem.
Provedení panelu se standartní regulací je základním provedením pro všechny vyráběné kotle

Každý kotel je možné vybavit u zákazníka elektronickou regulací ATMOS ACD 01 pro řízení celého topného systému v závislosti na venkovní teplotě, pokojové teplotě a čase. Tato regulace je schopna řídit i samotný kotel s ventilátorem s mnoha dalšími funkcemi.

As an extra accessories you can buy an automatic switcher which starts individual burner after wood burns down.

Each boiler can be fitted with ATMOS ACD 01 equithermal controller. It takes a control of the heating system based on datas collected from external sensors and on time. It can control suction fan of the boiler as well.

RECOMMENDED INSTALLATION WITH LADDOMAT 21 AND EXPANSION RESERVOIR

RECOMMENDED INSTALLATION WITH LADDOMAT 21 AND EXPANSION RESERVOIR

We recommend installing the boiler with Laddomat 21 or a thermo regulating valve with equalizing vessel 500 – 1, 000 litres. We also recommend installing the boiler with accumulating tanks of appropriate volume (e.g. 2,000 litres), which allow utilising electricity for heat accumulation or connecting solar panels. If necessary, the boiler can be connected into a system without accumulating tanks. This comes into account if you use natural gas (propane) or fuel oil.
