AI Technical Summary
Existing incinerators have slow preheating of exhaust gas when the equipment is not running, resulting in high energy consumption when the equipment is started and low air heat exchange efficiency.
A heat storage wall is installed inside the incinerator. The heat storage wall consists of an outer layer of refractory bricks, an inner layer of refractory bricks, and a middle heat storage layer. The heat storage layer uses porous heat storage ceramics. Heat exchange tubes are connected between the heat storage walls. The heat storage layer stores heat energy when the equipment is started, reducing cold start energy consumption.
This improved the preheating speed of exhaust gas during equipment startup, enhanced air heat exchange efficiency, and achieved energy-saving results.
