ENP - Gas/liquid fuel boiler
35 - 3.500 kW

ENERSAVE is a highly efficient pressurized steel boiler for function on gas or liquid fuels. The function is based on reversed flame in the fire chamber. All surfaces coming in contact with fire are cooled by water.

Its construction is cylindrical, with large fire chamber, improved heat exchanger surfaces and high performance turbinators. It is of high back- pressure in the fire chamber, designed to function with pressurized liquid or gas burners (the burner is not included).

The boiler has a robust construction which is ensured with quality control at every production step. Nominal working pressure is 6 bar. For models ENP 120-700kW, modular construction of the boiler is available on request.

Suitable control panel for one or two-stage burners. Tested and CE marked according to the European Standard for boilers EN 303-3.

WORKING PRINCIPLE

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.
