2060511 9014556 PCTABS00002 The present invention relates to an energy conservation apparatus to recover the waste energy in various industrial processes. The general assembly of the single stage ''Economizer'' heat transfer unit (1) is provided with tube (4) and twisted baffle (4c) tube (5) and twisted baffle (6), tube plates (2 and 2a) which are welded to heat transfer tubes (4) and (5). The exhaust flue gas is passed through the tubes to heat the water or chemicals to 85·-90·C, the pre-heated or cold water is directed to solenoid valve (17), check valve (16) and pipe (8). When the water is heated to set up temperature control by thermostatic device (9), solenoid valve (10) with check valve (11) discharges the hot water into the storage tank (55). Pressure vessel (1) is provided with safety valve (13) which relieves the excess pressure which is discharged through the storage tank (55). To control flue gas temperature into heat transfer unit (1), thermocouples (15) and (15a) are fitted. Variable speed fan (14) with impeller (14a) intakes the exhaust heat (flue gas) from the boiler which increases or decreases the excess air and provides high efficiency heat transfer which maintains the pressure drops into boiler combustion chamber.
