An arrangement related to a heating or steam boiler, which is provided with at least one tubular grate comprising a plurality of parallel tubes 3, fixed relative to each other at a distance and through which a heat-collecting medium is flowing, comprising grate rods 6 arranged between the tubes which are essentially situated below a connecting line between the tube centres. The rods 6 are displaceable by means of an adjustment device 8-10 from a position in which they abut against two adjacent tubes 3 in a tightening way, to a position in which air gaps are formed between the tubes and the rods. <IMAGE> |
