Plate packages for the cold side of a regenerative gasvorwärmers a flue gas desulphurization in a power plant

摘要

Plate stacks of plastic material for use in gas preheaters for smoke gas discharge conduit is sulfur for use in the cold end of the gasvorwärmers with the aim of the underlying enamelled plates from being destroyed by corrosion and vibration as a result of the interaction of the blowing pressure (vibration) and sulfuric acid (flue gas) to protect, wherein the plates by combs and are assembled to form solid plate, whereby the plates in small distances parallel to each other and to the gas stream are arranged, wherein the combs with their teeth define the distance between the plates from one another, whereby the plates in a minimum distance from the cleaning device are arranged, wherein the combs in slots of the plates are inserted, characterized in that the ridges are held by a locking element for a solid and rigid connection of the combs with the plates provides.
