Boilers type Šukoplam LUX with power range 15-80kW are ment primerily for combustion of bulk solid fuel (wood,coal) which is manually loaded through spacious middle boiler door. Boiler construction is completely in accordance with european standard EN 303-5.

                Boiler is constructed as „three drafted“ with one water cooled chamber and flue pipes which means that products of combustion pass water area in three occasions maximizing the heat exchange. First heat exchange is in boiler firebox, mostly by methods of irradiation, through large surface area of boiler firebox, second heat exchange is in the water cooled chamber of the boiler mostly by methods of irradiation and convection, and the third heat exchange is in flue pipes before the flue gasses exit the boiler mostly by methods of conduction and convection.

                Back area of the boiler firebox is equipped with fire resistant bricks which (after being heated up) irradiate heat  back to the boiler firebox and by doing so better the combustion of easily volatile gasses created by combustion of colid fuel. This effect makes combustion better and the boiler has higher efficiency. Boiler body is well insulated with mineral wool and boiler sheeting is protected with painting or powder coating processes.

                Boiler is meant for production of hot water in operating mode 110/90ºC and 90/70ºC with maximum allowed work pressure of 2,5 bar.

                Regulation of air flow needed for combustion of chunk solid fuel is done with draft regulator which moves  the flap on the bottom boiler door and by doing so increases or decreases the amount of air needed for the combustion.

                Protection of boiler from increased pressure is done by installing the safety valve on the appropriate place on the boiler, while protection of the boiler from increased temperatures is done by installing the safety heat exchanger which,if the need arises, cools down the boiler.
