Abstract
A quench system for cooling hot flue gases from combustion systems is disclosed. The quench system includes a venturi mounted in a quench vessel. The water level in the quench vessel may be raised or lowered in accordance with the flow rate of the gases to be quenched. When the pressure drop across the venturi is insufficient to achieve the desired cooling to adiabatic saturation temperature, the water level is increased so that the downcomer connected to the venturi is submerged and the additional pressure drop further cools the flue gases.
