FIELD: combustion apparatus or combustion processes. ^ SUBSTANCE: boiling pant comprises chimney with air duct interposed between the load-bearing ferroconcrete shaft and lining that define a gas discharging passage, and heat exchanger for heating air and fan for supplying heater air to the air passage of the chimney that underlie the gas discharging passage of the chimney. The air duct is separated into two section by two vertical baffles. The vertical baffles have openings through which heated air flows from one of the sections of the air duct of the chimney to the other section. ^ EFFECT: enhanced efficiency. ^ 3 dwg |
