4-1 Recovery Boiler Equipment and Operation

A boiler economizer is a heat exchanger device that captures the "lost or waste heat" from the boiler's hot stack gas. The economizer typically transfers this waste heat to the boiler's feed-water or return water circuit, but it can also be used to heat domestic water or other process fluids.

RECOVERY BOILER

May 25, 2011 · When the low pressure region appears it attract flue gas to flow onto it at a very high velocity. When the low pressure region inside the economizer collapses, the flue gas stream follows its normal path. The dent is formed due high velocity flue gas hits the external surface on and off. Over time, eventually, the outer surface will be damaged.
