Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

A heat exchanger is heating water on the tube side with steam condensing on the shell side. The water is entering at 45 0 F and exiting at 175 0 F. No instruments are available for measuring the tube side water flow but condensed steam from the shell side is being collected at a rate of 43 GPM. If the tube area of the exchanger is 350 Ft2 , and the overall heat transfer coefficient clean was 900 BTU/Hr.Ft2 F0, how much has the overall heat transfer coefficient changed, if at all? Note: Latent heat for water/steam at 212 0 F is 970 BTU per pound of water. A gallon of water weighs 8.34 lbs.
Hot exhaust gases of a stationary diesel engine are to be used to generate steam in an evaporator. Exhaust gases (cp = 1051 J/kg·K) enter the heat exchanger at 550°C at a rate of 0.25 kg/s while water enters as saturated liquid and evaporates at 200°C (hfg = 1941 kJ/kg). The heat transfer surface area of the heat exchanger based on water side is 0.5 m2 and overall heat transfer coefficient is 1780 W/m2·K. Determine the rate of heat transfer, the exit temperature of exhaust gases, and the rate of evaporation of water.

Required information Consider a water-to-water counterflow heat exchanger with these specifications. Hot water enters at 70°C while cold water enters at 20°C. The exit temperature of the hot water is 15°C greater than that of the cold water, and the mass flow rate of the hot water is 50 percent greater than that of the cold water. The product of heat transfer surface area and the overall heat transfer coefficient is 2200 W/K. Take the specific heat of both cold and hot water to be cp= 4180 J/kg.°C.
