A method for combustion of sulfur-containing fuel in a circulating fluid bed combustion system wherein the fuel is burned in a primary combustion zone under reducing conditions and sulfur captured as alkaline sulfide. The reducing gas formed is oxidized to combustion gas which is then separated from solids containing alkaline sulfide. The separated solids are then oxidized and recycled to the primary combustion zone.

Reducing mode circulating fluid bed combustion

Combustion gas passes upwardly through the radiant section of a fired process heater having vertical tubes in such manner that the gas is in predominantly back-mixed flow condition in the lower portion of the radiant section and predominantly plug-flow condition in the upper portion of the radiant section.

Fired process heater

A process for removing entrained liquid and volatilized melt from a gaseous stream produced in molten salt processing wherein the gaseous stream is passed through fluidized, solid particulate material and entrained melt solidifies on the particulate material.
