Abstract

The boiler comprises a roof and two side walls (22, 25) formed as membrane walls each having a lower header (23, 26) at the bottom and being connected at the top with at least one upper header (27). The boiler has at least one suspended heating surface section comprising several heating surface tubes (30) supported at the top and passed from the roof down to lower headers lying crosswise in the boiler. The roof in the boiler is a membrane wall (28), and the heating surface tubes extend uninterruptedly from one lower header up through and above the roof and return through the roof to an adjacent lower header, and have been passed in a gastight and longitudinally displaceable manner through the membrane wall of the roof.
