  • Product Description

    Wallstein Power GGH cross flow type used in thermal power plants, especially in case where the arrangement allows to adopt the GGH direct to the FGD.The flue gas and clean gas are directly heat exchanged by tubes made from fluoropolymer. All elements which have direct contact with flue gas are protected by fluoropolymers or those elements have excellent corrosion resistant properties. Using PGGH, it can absorb the heat contained in the high-temperature corrosive flue gas emitted by power plants, heat up the net flue gas temperature, and meet the environmental standards for flue gas emissions.

  • Product Description

    Wallstein HDS(Heat Displacement System) mainly used in thermal power plants, in case the cooler and reheater parts need to be separated because of space and arrangement reasons.

  • Product Description

    IGGH (Incineration GGH) is specifically used in the field of waste incineration plants. IGGH ca be used also in hazardous and Bio waste plants. The flue gas and clean gas are directly heat exchanged by tubes made from fluoropolymer. All elements which have direct contact with flue gas are protected by fluoropolymers or those elements have excellent corrosion resistant properties. Using IGGH, it can absorb the heat contained in the high-temperature corrosive flue gas emitted by waste incineration, heat up the net flue gas temperature, and meet the environmental standards for flue gas emissions.

  • Product Description

    The Wallstein HRS system is made from fluoropolymer allows to recover heat below the acid dew point of the flue gas. HRS has 3 variants: Preheating the air 2. Preheating the condensate 3.And switching between the heat supply network and condensate line of the plant.

    如果不降低烟气中的水分含量,单纯依靠加热提高烟气的排放温度,即使加热到很高的温度,在寒冷地区,仍然不能有效改善白烟现象,并且还会无谓消耗巨大的能源。 针对烟囱排放烟气在冬季时容易发生白烟,首先对净烟气进行冷凝除湿,降低含水率,脱除的水分可以回收再利用。然后再利用原烟气余热适当加热净烟气到合适的温度排放,即可大大改善甚至完全消除白烟现象。采用这种方法,在脱白的同时,可以实现烟气余热利用,节省能源,同时还可以进一步降低净烟气中灰尘含量,并实现节水和回收利用,可谓一举多得。采用沃斯坦脱白工艺及DPS系统后,脱白效果显著:

  • Product Description

    DFL (Duct Fluoropolymer Lining) is the use of fluoropolymer material to lining the flue gas ducts to prevent corrosion of flue gas and further leakage. With this process, it has strong corrosion resistance, can withstand dry and wet fumes of various components at various temperatures, is free from ash blocking, is insensitive to temperature changes, is resistant to aging, and has a long lifespan. For an expensive titanium metal material is the best alternative option. The fluoropolymer lining strictly follow the standard construction, paying special attention to the connection area, the flange edge, the opening area, the variable diameter section, the special-shaped components, etc. to ensure that the metal components of the flue gas and smoke are completely isolated. Corrosion lining construction should be completed 100% inspection.
