Abstract

The device is for the input of hot gas into heating surface pipes (3) welded with a pipe plate (1) of a heating boiler. In each heating surface pipe is an inlet pipe (5), which has a conically narrowing inlet (5a) located at a distance from the pipe plate. On the outside of the pipe plate is an insulation (6) between the inlet pipes. The inlet pipes are suspended inn the pipe plate and support on the pipe plate/heating surface pipe assembly. On each inlet pipe, prior to its suspension in the pipe plate, a ring-shaped insulation piece (6) is pushed.
