Steam heated non-storage calorifiers. A common design for a steam to water non-storage calorifier is shown in Figure 2.13.4. This is known as a ‘one shell pass two tube pass’ type of shell and tube heat exchanger and consists of a U-tube bundle fitted into a fixed tube sheet.

Heating Vats and Tanks by Steam Injections | Spirax Sarco

Example 2.11.1 - Determine the steam load to heat a tank of water by steam injection. These calculations (steps 1 to 5) are based on Examples 2.9.1 and 2.10.1 as far as heat losses are concerned, but with the tank containing water (cp = 4.19 kJ/kg °C), instead of weak acid solution and the water being heated by steam injection rather than a steam coil.


temperature rise using 50 PSIG saturated steam is shown on Curve 1 (page 8). The curve shows the Lbs./Hr. of steam required to meet the demand as the water flow through the tube bundle decreases. The condensing rate in this example is approximately 33% at 0 PSIG. Without the fouling factor, the condensing rate will be much higher at 0 PSIG.

Steam Superheater in Boiler: Role, Benefits, Types

The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its …
