FIELD: process engineering.

SUBSTANCE: invention relates to heat engineering and may be used for cleaning flue gas of residential heat supply systems from harmful impurities. Proposed bed comprises case consisting of sections, top and bottom joint assemblies, detachable top and bottom gratings arranged on section top and bottom edges. Detachable vertical zigzag-shaped perforated channels are arranged between said gratings to make vertical zigzag gas ducts. Note here that section inner surface is coated by perforated jacket to make inner space between section inner surface and said jacket. Vertical zigzag-shaped perforated containers and said inner space are filled with pumice pellets prepared from metallurgical slag with lime factor M>1 and pellet diameter of 5-10 mm.
