Structure Analysis of GGH Heat-Exchange Panel Elements for Desulfurization

The paper deals with the proper design of GGH(Gas-Gas Heater) panel elements of desulfurization equipments in a thermoelectric power plant. When fossil fuels such as coal, petroleum et cetera are burnt to ashes, sulfur oxide compounds are produced, and calcareous sludges are deposited at GGH panel elements. In this case, operation of a power plant equipments is interrupted, and a tremendous economic loss comes into existence. One of the purposes of the paper is to find stress-strain distribution when properly model(A3003) on the GGH panel elements through the structure analysis. In the structure analysis, GGH panel elements improved aluminium alloy are demonstrated good rigidity and stress when compare with the steel material.
