shell and tube exchangers

those that are used in the petrochemical industry which tend to be covered by standards from TEMA, Tubular Exchanger Manufacturers Association (see TEMA Standards); those that are used in the power industry such as feedwater heaters and power plant condensers. Regardless of the type of industry the exchanger is to be used in there are a...

shell and tube heat exchangers

The shell and tube exchanger consists of four major parts: Front Header—this is where the fluid enters the tubeside of the exchanger. It is sometimes referred to as the Stationary Header. Rear Header—this is where the tubeside fluid leaves the exchanger or where it is returned to the front header in exchangers with multiple tubeside […]

Which Heat Exchanger Is Best? The Three Main Types Explained.

Which Heat Exchanger Is Best? The Three Main Types Explained. Heat exchangers all work by passing a hot fluid and a cold fluid across opposite sides of a piece of metal. The heat from one fluid passes across the metal (which is thermally conductive) into the other fluid without the fluids making contact. High fluid […]

How to start with designing a heat exchanger?

Steps for design of heat exchanger Calculate the effectiveness. Calculate the capacity rate ratio. Calculate the overall heat transfer coefficient. Determine NTU. Calculate the heat transfer surface area. Calculate the length of the tube or heat exchanger. For sizing a heat exchanger, several thermal phenomena should...
