ENP hot water boilers have high back-pressure in the fire chamber, designed to function with pressurized liquid or gas burners.
The function is based on reversed flame in the fire chamber, with three passes of the exhaust gases. All surfaces coming in contact with fire are water cooled. Most of the heat is transferred to water through radiation. The first two passes are in the fire chamber, then the exhaust gases are guided to the peripheral smoke tubes, in which the third pass is realized. Special turbinators are positioned inside the smoke tubes to increase boiler’s efficiency.
After passing the smoke tubes the exhaust gases are guided to the smoke box and then to the chimney.
