Fiberglass chimney flue

Although the flue gas temperature drops to 50~80 ℃ after desulfurization, the flue gas also contains strong corrosive media such as hydrogen fluoride and chloride, and the moisture content is high, which increases the corrosion probability of the inner wall of the chimney flue. When designing the chimney flue, it should be considered that the flue gas temperature without wet desulfurization in emergency state is as high as 150~200 ℃, so the wet desulfurization chimney flue has high requirements for corrosion resistance and temperature resistance.

　1. glass steel chimney structure:It is composed of inner lining layer, structural layer and outer surface layer from inside to outside, and is divided into several structures such as self-supporting type, zipper type, tower type, sleeve type or multi-tube type. The overall winding molding process has excellent mechanical properties, especially suitable for the operating conditions of coal-fired power plants.

2. glass steel chimney product features:

1, excellent chemical corrosion resistance, excellent fatigue resistance, are better than titanium nickel alloy, long service life;

2. Small specific gravity, large diameter, light weight, high strength, low cost, and lower cost than foam glass bricks, titanium nickel alloy plates, etc;

3, easy to manufacture and install, good quality control, short construction period;

4, operation and maintenance costs zero cost, than foam bricks and scale coatings and other very little maintenance;

5. The overall structure has no corrosion weak points, eliminating solder joint corrosion, hydrogen corrosion, metal corrosion and electrochemical corrosion.

　3. glass steel flue:That is, glass fiber reinforced plastic is selected for the conveying flue in the "desulfurization flue tower integration" project because of its excellent corrosion resistance and durability, which saves anti-corrosion costs and has a service life of more than 30 years, which is consistent with the life cycle of thermal power plants. At the same time, it has a light weight, can be erected in a large span, does not need bracket support, and saves construction costs. It can also reduce the power consumption and operating costs of thermal power plant equipment, eliminate the chimney in the traditional mode, and save the construction cost.

　　4. application areas:Coal-fired power plants, metal smelting, chemical, petroleum, steel, building materials, coking, pharmaceutical and other industries.

5. implementation standards:

HG/T20696-1999 Design Regulations for FRP Chemical Equipment

HG/T3983-2007 "Chemical Corrosion Resistance Field Winding FRP Large Vessels"

GB 50051-2013 Code for Design of Chimney

Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components. Forging can eliminate the defects such as loose casting in the smelting process and optimize the microstructure. At the same time, due to the preservation of the complete metal flow line, the mechanical properties of forgings are generally better than castings of the same material. Related machinery in high load, severe working conditions of important parts, in addition to the shape of a relatively simple available rolling plate, profile or welding parts, the use of forgings.
