hot flue การใช้

• Natural gas condensing boilers and hot air furnaces increase efficiency over standard hot flue models.
• The hot flue gases are led into the chimney via a heat exchanger with manual or automatic cleaning of the reheating surfaces.
• The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water.
• The hot flue gas exits the regenerator after passing through multiple sets of two-stage cyclones that remove entrained catalyst from the flue gas.
• That causes the bottom of the vertical column of hot flue gas to have a lower pressure than the pressure at the bottom of a corresponding column of outside air.
• That causes the bottom of the vertical column of hot flue gas to have a lower pressure than the pressure at the bottom of a corresponding column of outside air ."
• Exhausting extremely hot flue gases from gen-sets can be done by factory-built positive pressure chimneys ( certified to UL 103 test standard ) or general utility schedule 40 black iron pipe.
• Some fuel-burning industrial equipment does not rely upon natural draft . Many such equipment items use large fans or blowers to accomplish the same objectives, namely : the flow of combustion air into the combustion chamber and the flow of the hot flue gas out of the chimney or stack.
• If there is a backflow in the chimney, it is possible that the cool air and the hot flue gases both entering into the appliance s room via the openings of the gas appliance draught diverter, which can cause high level of carbon-monoxide in the air of the room, resulting possible deaths or permanent disability.
