A liquid desiccant regenerator is provided including an upstanding hollow reboiler having upstanding peripheral sides, a bottom and a top. A plurality of laterally space upstanding tubular flues are provided in the reboiler and open upwardly and downwardly through the top and bottom. A flue plenum chamber is disposed over the top into which the upper ends of the tubular flues open and a flue pipe opens upwardly from the plenum chamber. A combustion chamber is disposed below the bottom including low pressure gas burner structure therein and into which the lower ends of the flues open. An upper portion of the reboiler includes a lateral extension and a still column is supported from the lateral extension and is positioned relative thereto for regenerated liquid desiccant drainage from the lower end of the column into the lateral extension. The reboiler is designed to be operated with a predetermined liquid desiccant level above and below the upper and lower extremities of the lateral extension and the reboiler includes a scum baffle protected liquid desiccant outlet disposed substantially at the aforementioned level and extends above and below the latter.
