Standard height of Tower Type Gas Boiler Chimney
Gas fired boilers shall comply with the du Emission Standard for Boilers (GB13271-2001). If there are buildings within a radius of dao200m around the chimney height of a new zhi boiler, the chimney height shall be 3m higher than that of the building. The chimney height of a gas fired boiler shall be determined in accordance with the requirements of the approved environmental response report, but shall not be lower than 8m. Therefore, the minimum chimney height of the gas boiler should be 8 meters.
Standard for the design of Tower Type Gas Boiler Chimney
1. The steel chimney should have sufficient strength and stiffness, and the thickness of the chimney wall should consider a certain amount of corrosion margin. When the height of the chimney is 20~40m and the diameter is 0.2~1.0m, the thickness of the unlined cylinder should be 4~10mm and that of the lined cylinder should be 8~18mm.
2. When the ratio of chimney height to diameter is more than 20, reliable pulling rope must be set, with 3 to 4 pulling ropes arranged along the circumference of an equal arc.
3. The chimney and the connecting part of the foundation are generally made into cones, and the thickness of the supporting plate is generally 20~40mm.
4. Steel chimney with lining, lining can be supported in sections, each section length 4~6m, between the lining and the cylinder to maintain a gap of 20~50mm, and should be installed at the top of the protective ring plate will cover the lining.
5. Steel chimneys should be welded stainless steel chimneys processed and manufactured by professional factories.
Precautions installation of Tower Type Gas Boiler Chimney
1. When installing the chimney, the flange should be embedded with asbestos rope, and the perpendicularity of the chimney should be checked by the method of lifting the vertical line. If there is any deviation in the flange joint pad flat correction.
(2) Pull wire (wire rope) with flange bolts, pay attention to the tightness of the three wire ropes should be roughly the same.
(3) According to the requirements of the environment and local authorities, the height of the chimney can be shortened or increased.
