Heat Transfer Examples

Example (2)A two-tube-pass, one shell-pass,shell-and-tube heat exchanger:condenser, evaporator, feedwater heater, steam generator

The first tube-pass flows is in the same as the shell-pass: parallel flow. The second one flows in the opposite direction to the shell-pass: counterflow.

Example (3)

Blast furnace: air is blowing into the furnace to maintain temp. that is higher than 800°C. Melting iron flows into ladle.

Continuous casting can be achieved by cooling the molten iron in a convey system. Precise temperature control is critical to the quality of the final product.

Example (4) Weather Convection

Day time: sea breeze coming toward the land as a result of natural convection

Night time: wind blowing from land to sea because of thenatural convection
