Abstract

Some metal compounds in coal vaporize and form fumes during the combustion. The fumes are usually contained in the exhaust gas. For coal-fired combined power generation systems such as pressurized fluidized bed combustion, hot metallic vapors are introduced in gas turbine. As this phenomenon causes corrosion problem of the turbine blades, it is necessary to control the formation of those fumes, which include alkali metal compounds. In this paper, the evolution behavior of alkali metal compounds, especially for sodium compounds, has been studied, using a drop tube furnace with a low-pressure impactor.
