The Osby GTPÅ is a 3-pass boiler consisting of a horizontal pressure vessel insulated with 150 mm mineral wool, covered with white enamel AluZinc plating. Combustion takes place in the firing tube, then the flue gases turn in the turning chamber, passing through the first and second tube pass. The flue gas outlet is at the rear of the boiler.
The entire firing tube including turning chamber and burner installation is water-cooled, and elastically mounted between the boiler ends. In this way, the firing pipe can expand, and there is no need for masonry work in the turning chamber and around the burner installation.
The flue gas tubes are 4 mm thick as standard, which provides increased strength and service life. To avoid cracks in the turning chamber tube ends, the tubes are countersunk and welded in line with the turning chamber end.
Water quality is especially important for steam boilers. Based on analysis protocols or water samples, we can recommend suitable water treatment equipment.
