FIELD: heat power engineering.
SUBSTANCE: nozzle comprises housing (1) with docking units (2). The first stage of cleaning is made of vertical perforates members (3). Each of the members is composed of vertical perforated wall with bottom (4) and vertical perforated detachable side lid (5). Perforated member (3) is made of corrosion-resisting material and is filled with particles of disintegrated slake lime. The second stage of cleaning is made of perforated members (8) filled with activated coal. Perforated members (3) and (8) are mounted inside gas passages (10) that are separated from air passages (11) with vertical baffles. Near the bottom the air passages are connected with sucking slots (12) thus forming a plate heat exchanger. Inclined chutes (13) underlie the heat exchanger and are connected with drain pipeline (15) through valve (16).
EFFECT: reduced sizes and simplified structure.
