Heating boiler, especially solid fuel boiler, has cleaning arrangement with vertical plate in hot gas flow channel between adjacent essentially flat, preferably vertical heat exchanger surfaces

摘要

The heating boiler (1) has an arrangement (2) for cleaning heat exchanger surfaces (3) in the boiler with at least one vertical plate (5) in the flow channel (4) of the hot combustion gas between two adjacent essentially flat and preferably vertical heat exchanger surfaces. The plate has flexible lateral cleaning protrusions (6) that can be brought into contact with the surfaces. AN Independent claim is also included for the following: a method of cleaning essentially flat heat exchanger surfaces in a boiler.
