Abstract:
A heating apparatus comprising a boiler adapted to burn an energy source white discharging exhaust gas produced when the energy source is burnt, the boiler including an exhaust port, and a distribution board, the apparatus using waste heal to reduce the consumption of the energy source while being environmentally friendly, further comprising:at least one flue connected to the exhaust port of the boiler, the flue extending through an indoor space, and having a discharge port arranged outwardly from the indoor space; at least one fan unit installed in the flue, the fan including: an enlarged pipe having a diameter larger than that of the flue while being provided at both ends thereof with fitting portions allowing the enlarged pipe to be connected to the flue, the enlarged pipe being divided into two pipe portions coupled to each other by bolts; and a fan arranged in the enlarged pipe while serving to forcibly circulate exhaust gas existing in the flue, the fan having high resistance to high temperature and moisture, while thereby discharging the exhaust gas into an atmosphere after filtering the exhaust gas to contain a reduced amount of noxious substances, using a mist filter formed in the flue due to a temperature difference between the flue and the exhaust gas, or without any filtration of the exhaust gas by the mist filler; and at least one water drainage port provided at the line.
