<p>A method of reducing flue gas emissions that may include: cooling a flue gas upstream of a first emission control device with at least one heat exchange device; and transferring heat directly or indirectly from the at least one heat exchange device to an absorption chilling or other heat-activated chilling system. The method may also include cooling the flue gas at one or more additional locations using the absorption chilling or other heat-activated chilling system and/or rejecting heat from the absorption chilling or other heat- activated chilling system to one or more locations. Methods and apparatus disclosed herein may be used to effectively decrease pollutant levels in flue gas streams, such as mercury, particulate matter, and hydrogen chloride, and some embodiments may also be used to recover water from the flue gas stream.</p>
