Exhaust gas desulfurization method in pressurized fluidized-bed reactor system and pressurized fluidized-bed reactor system

摘要

To properly remove a sulfur oxide (especially SO) from an exhaust gas at a low cost for countermeasure equipment for removing SO.SOLUTION: A pressurized fluidized furnace system uses sodium hydroxide as a desulfurization agent for wet desulfurization on a combustion exhaust gas passing through a turbine of a supercharger, and discharges a smoke exhaust-processed gas to the atmosphere via a smokestack. The pressurized fluidized furnace system sprays sodium hydroxide liquid from a spray nozzle in a post-combustion exhaust gas passage between the turbine and a smoke exhaust processing device.SELECTED DRAWING: Figure 1
