Detailed Description

As shown in fig. 1-3, the utility model provides a technical solution: an SGH flue gas heater comprising: the hot-water boiler comprises a main body 1, a Teflon lining plate 3 and a non-finned heat exchange tube 4, a cleaning tube opening 2 is arranged at the top of the upper end of the main body 1, the main body 1 comprises an upper heating box 101, a lower heating box 102 and a smoke outlet tube 103, the upper end top of the upper heating box 101 is provided with the lower heating box 102, the smoke outlet tube 103 is arranged on two sides of the upper end of the lower heating box 102, the finned heat exchange tube 5 is arranged on the inner side of the upper heating box 101, the Teflon lining plate 3 is attached to the inner wall of the lower heating box 102, and the non-finned heat exchange tube 4 is arranged on the inner side of the Teflon lining plate 3. The upper heating box 101 and the lower heating box 102 constitute a detachable structure, and the upper heating box 101 and the lower heating box 102 are closely attached. The middle part of the upper end of the upper heating box 101 is provided with a cleaning pipe orifice 2. The finned heat exchange tubes 5 are uniformly distributed along the interior of the upper heating box 101.
