a flue gas purification and heat recovery apparatus, in which the flue gases from a heating boiler (1) are directed to a heat exchanger (2), where the flue gases yield their heat to a substance, such as air, flowing on the secondary side (3) of the heat exchanger. The warm-air outlet side (5) of the heat exchanger is connected to a regenerative air-conditioning and heat recovery apparatus (6). |
