<p>PURPOSE:To recover waste heat from a boiler flue at a high efficiency, as well as to prevent environmental pollution or corrosion due to the combusted product from resulting in, by arranging gas purifying members made of Moonon (a trade name) for purifying a flue gas. CONSTITUTION:By the operation of a blower 19, the flue gas in a flue B flows through a flue gas conduit system 13 in accordance with the opening of a flue damper 11, is led into a leading chamber 8 of a heat recovering-purifying column 1, is passed through the gas purifying members 5 to be purified into a high temperature gas, and then is led via a recovered heat conduit system 15 into a recovered heat utilizing apparatus 18 to be offered as a heat source for boiling water. While the flue gas is passing through the labyrinth of the gas purifying members 5, it is purified into an innoxious high temperature gas by the gas purifying members 5. Consequently, the recovered heat transfer conduit system 15 and the recovered heat utilizing apparatus 18 are prevented from being corroded by sulfuric acid and the heat exchange efficiency of the recovered heat utilizing apparatus 18 can be prevented from lowering.</p> |
