This
work presents the application of waste heat from exhaust gases of gasoline
generator through a heat exchanger for household water heating. Two cases were
experimented. First, was when water was supplied and filled the heat exchanger
without discharging through the tap (retained). Second, was when water was
continuously supplied to the heat exchanger and continuously discharged through
the tap. In both cases, the temperatures of water and exhaust gases were
measured. Measurement showed that during one hour of
operation, the water temperature increased from 300C to 630C
in the first case and from 280C to 490C in the second
case. The average mass flow rate of water in the first case, average
mass heating rate of water in the second case and average mass flow rate of
exhaust gas in the first and second cases were determined to be 0.01 kg/s,
0.044 kg/s, 0.02 kg/s and 0.09 kg/s respectively. The
heat gain rate of water in first and second cases were determined to be 1.28 kW
and 22.58 kW respectively.
