5.1 Shell-and-Tube Heat Exchangers
homepages.wmich.eduExample 5.2 Miniature Shell-and-Tube Heat Exchanger A miniature shell-and-tube heat exchanger is designed to cool engine oil in an engine with the engine coolant (50% ethylene glycol). The engine oil at a flow rate of 0.23 kg/s enters the exchanger at 120°C and leaves at 115°C. The 50% ethylene glycol at a rate of 0.47 kg/s enters at 90°C.

file.scirp.orgheat exchanger (PH). Fire-tube boiler components are shown in Figure 6. A fire-tube boiler is a type of boilers in which hot gases from the fire pass through one or more tubes within the boiler. It is one of the two major types of boilers, the other being the water tube boiler. A fire tube boiler can be either horizontal or vertical.
