In the case of a stoker-fired, municipal-refuse boiler, the heat flux is not high enough to lead to a temperature spike, so the corrosion proceeds in a uniform fashion. In summary, the three temperature regimes of fire-side corrosion are: less than about 300 o F, where sulfuric acid dew-point corrosion occurs, 500 o - 750 o F on furnace walls, and greater than 1000 o F on superheater and
