<p>PURPOSE:To provide a boiler for which fuel that contains a corrosive material such as chlorine compounds, etc., may be used. CONSTITUTION:The subject method of preventing corrosion of a fluidized bed boiler is to provide an evaporator 7 in the convection flow heat transfer section 5, introduce part of the particles that form the fluidized bed layer 1 to a heat exchanger 8 which has a superheater 4 in itself, and take out the steam that is generated in the evaporator 7 through a superheater 4. Witn this method the corrosion of the superheater 4 is prevented and as a result it is possible to obtain superheated steam of high temperature by using a fuel that contains a corrosive material such as chlorine compounds, etc., and by using this steam it is possible to raise the effect of the Rankine cycle when a steam trubine is driven.</p> |
