AI Technical Summary
Technical Problem
The waste heat in the high-temperature flue gas at the tail end of the boiler was not effectively recovered, resulting in low energy utilization efficiency and significant energy waste in thermal power plants.
Method used
Design a coal-fired power plant energy-saving and emission-reduction device. High-temperature flue gas is introduced into the first chamber through a flow guiding component. The heat of the flue gas is transferred to the heat exchange medium in the second chamber by a heat exchange unit, and then supplied to the boiler to reduce fuel consumption.
Benefits of technology
This improved waste heat utilization, reduced boiler energy consumption, achieved the goal of energy conservation and emission reduction, and reduced coal consumption.
