Experimental study on waste heat recovery characteristics of inorganic ceramic membrane flue gas

The wet saturated flue gas discharged by coal-fired utility boilers leads to a large amount of low-temperature wasteheat loss. Inorganic ceramic membrane is acid-base resistant and has strong chemical stability. It an ideal material forrecovering waste heat from gas. experiment recovery was carried outwith inorganic as the core, characteristic parameters at tailof boiler were analyzed; taking 316 L stainless steel comparative object, strengthening effect inorganicceramic film on improving power composite transfer coefficient discussed. results showthat mainly evaporation latent water, accounting for about90%; circulating water used cooling medium, capacity stronger;compared with when air membraneflue more significant, enhancement high 9; increasing gasflow helpful improve coefficient; same time, can also recover condensate quality. this paper provide areference application in recovery.
