Method and device for largely dust-free cleaning of heating boilers

摘要

In the cleaning method, combustion residues deposited in the flow ducts for the flue gases are detached, with the combustion chamber sealed off from the outside, by means of cleaning brushes moving to and fro in the ducts, and simultaneously sucked off through a corresponding suction opening. The combustion chamber is sealed off from the outside by means of a cleaning device in the form of a cover which is to be inserted into the combustion door opening of a heating boiler to be cleaned and which has at least one longitudinal guide for a long-handled guide means of a cleaning brush. The cover expediently consists of an annular part, which can be inserted into a combustion door opening, and a guide plate which can be rotatably accommodated in the region of a partial annular cutout and which has a longitudinal guide for the long-handled guide means of the cleaning brush.
