Abstract

Abstract: Heat transfer between two streamsis common, well established and perfectly commercialized, in some industrialapplications in all production unit where more than one reactant is to bepreheated or pre-cooled for chemical reaction and same as post heating and postcooling required of multiple streams at same or different temperaturesrequired, To overcome this problem, we need more than one heat sinks with oneor more than one heat source that will minimize the covered volume per unitheat transfer area by increasing thermal efficiency, to overcome this problemwe need to move towards Multi Stream Heat Exchanger for handling multiplestreams at once for the exchange of heat. Multi stream heat exchanger isopening of a new class of heat transfer equipment which deals more than twodifferent streams for heat exchange, with a little bit increase in complexitythe operational cost will decrease and improve the thermal efficiency of heattransfer equipment, which minimize thermal losses and maximize the heatutilization which directly decrease the equipment size and capital cost. Thepresent study involves the designing of Floating Head Multi Stream HeatExchanger and where two cold streams flow through the inner and outer pipe andone hot stream is flow through central pipe at same flow rates and itsperformance analysis iscarried out where we calculate experimentally the heat duties of both hot andcold fluids, effectiveness by using Floating Head Multi-Stream HeatExchanger.
