A boiler system comprises a housing with a generally cylindrical shape extends between first and second walls to provide a generally cylindrical space. A fire tube is positioned near a bottom of the generally cylindrical housing and extends longitudinally from a first wall of the cylindrical housing to a fire tube end wall. The boiler system also includes a burner with a generally cylindrical housing which defines a generally cylindrical chamber and an end plate. The burner extends into the fire tube, and the fire tube provides a combustion chamber where combustion of an air-fuel mixture is accomplished using the burner. The end plate of the burner is adjustable so as to adjust the flame that extends from within the burner housing into the fire tube.

The invention relates to a tubular boiler with a heat exchange tube with at least one helical layer situated in a heat exchange chamber, and which includes a set of laterally joined spirals. The boiler includes, an inner side of the helical layer, an oven that is rigidly joined to said layer and connected to a feeder by means of which fuel is supplied. The boiler also includes an output collector for collecting ash and slag, which connects the inside of the heat exchange chamber to the outside of the boiler, and a forced-air-current generator that generates a movement of air inside the boiler and directs it to the oven. This movement of air moves the ash and slag along the at least one helical layer to the output collector.
