2 in 1 pellet and pyrolysis boiler DM-STELLA combines the best properties of pyrolysis and pellet boilers, guaranteeing increased economy and comfortable use. The boiler is universal in use, because it works not only onsolid fuel, but also on pellets. Pellet boilers provide accurate temperature maintenance, excluding fuel overconsumption. Easily controlled, allowing you to set the desired day and night temperatures. Fuel depends little on fossil fuel prices (gas, oil) and electricity. The stage of coordinating the heating project with gas suppliers is excluded. Also, vegetable fuel is ecologically clean and does not produce new emissions of CO2 into the atmosphere. Using pellet heating - you help nature.газа, цена которого сопоставима со стоимостью пеллетного системы в целом.

Так же растительное топливо экологически чистое, и не производит новые выбросы СО2 в атмосферу. Используя пеллетное отопление - вы помогаете природе.

Pyrolysis solid fuel boilers from DM-STELLA, also known as gas generator boilers, work on the principle of pyrolysis combustion (or dry distillation) of solid fuel, the essence of which is the high-temperature decomposition of fuel into volatile (pyrolysis) gases and solid residue under the influence of high temperature and under conditions of oxygen deficiency. The pyrolysis process takes place at a temperature above 1100 ° C. The advantage of such pyrolytic decomposition can be called exothermic processes, which significantly improve the heating of air, which is used later for drying the fuel in the bunker and feeding it through the nozzle to the combustion zone.

The formation of a high-temperature torch - a distinctive feature of pyrolysis boilers - occurs in the process of mixing released gases and supplied oxygen. It is noteworthy that activated carbon also burns in this torch, thanks to which the concentration of harmful substances in the flue gases of the boilers is minimal, the clogging of the heat exchanger pipes is insignificant, and the volume of CO2 emitted into the atmosphere is several times less than the permissible norm.

Due to the unique completeness of combustion and fuel decomposition, the ash content of any used fuel is maximally reduced. That is why DM-STELLA solid-fuel pyrolysis boilers are cleaned much less often than usual long-burning solid-fuel boilers.
