SIZING AND EXPERIMENTAL PERFORMANCE ANALYSIS OF FLOATING HEAD MULTI STREAM HEAT EXCHANGER

Abstract

Heat transfer between two streams is common, well established and perfectly commercialized, in some
industrial applications in all production unit where more than one reactant is to be preheated or pre-cooled for chemical
reaction and same as post heating and post cooling required of multiple streams at same or different temperatures
required, To overcome this problem, we need more than one heat sinks with one or more than one heat source that will
minimize the covered volume per unit heat transfer area by increasing thermal efficiency, to overcome this problem we
need to move towards Multi Stream Heat Exchanger for handling multiple streams at once for the exchange of heat.
Multi stream heat exchanger is opening of a new class of heat transfer equipment which deals more than two different
streams for heat exchange, with a little bit increase in complexity the operational cost will decrease and improve the
thermal efficiency of heat transfer equipment, which minimize thermal losses and maximize the heat utilization which
directly decrease the equipment size and capital cost. The present study involves the designing of Floating Head Multi
Stream Heat Exchanger and where two cold streams flow through the inner and outer pipe and one hot stream is flow
through central pipe at same flow rates and its performance analysis is carried out where we calculate experimentally the
heat duties of both hot and cold fluids, effectiveness by using Floating Head Multi-Stream Heat Exchanger.
