DEVICE FOR CLEANING AND UTILISATION OF FLUE GASES OF ROOF BOILER Russian patent published in 2017 - IPC E04H12/28 F23J15/02 

FIELD: heating.

SUBSTANCE: device for cleaning and utilisation of flue gases of a roof boiler includes a box, made of corrosion-resistant material, connected to the atmosphere on opposite edges through chimneys, equipped with deflectors placed on the roof of the roof boiler room, in the bottom of which there are openings connected to the chimney of the heat generator and equipped with cartridges. Perforated baskets, filled with pumice granules, are placed inside the box on the support bars and a vertical perforated partition. The pumice is made of metallurgical slag with a lime factor of M>1 and a granule diameter of 5 to 10 mm. Above the baskets there are washing branch pipes, perforated below and connected outside the box to the wash water manifold. The bottom of the box is made with a slope I to the openings. The bottoms of the cartridges are connected to an acid condensate manifold, which is also connected to a drain manifold and an adsorber filled with adsorbing agent, i.e. pumice granules of metallurgical slags, and equipped with a hydraulic gate connected to a storage tank, which is connected through a condensate pump to a feedwater pipeline of the heat generator, the adsorber wash water pipeline and the wash water manifold.

EFFECT: increased reliability and efficiency of the device.
