A shell and tube heat exchanger where water flowing through tubes is heated by steam within the shell.



Related Terms

SHELL AND TUBE

A type of heat exchanger in which a nest or coil of tubes or pipes containing a fluid is inserted into a shell containing a second fluid. Heat is transferred from one fluid to the other through the tube or pipe walls.

WATER TUBE

A tube in a boiler having the water and steam on the inside and heat applied to the outside.

SHELL and TUBE CONDENSER

A heat exchanger where one fluid circulates through tubes enclosed between two end-plates in a cylindrical shell and where the other fluid circulates inside the shell.

SURFACE CONDENSER

A shell-and-tube heat exchanger in which steam is condensed on the shell-side while cooling water flows through the tubes. The condensate and cooling water leave the system separately.

JET CONDENSER

A direct contact heat exchanger in which steam to be condensed comes into direct contact with the cooling water (cold condensate) which is usually introduced in the form of a spray from a jet.

INTERNAL FLOATING-HEAD EXCHANGER

Tube-and-shell heat exchanger in which the tube sheet (support for tubes) at one end of the tube bundle is free to move.

BAUDELOT COOLER

Heat exchanger in which water flows by gravity over the outside of the tubes or plates.

DISCHARGE TUBE

  1. An evacuated enclosure containing a gas at low pressure, through which current can flow when sufficient voltage is applied between metal electrodes in the tube. Also known as electric-discharge tube. 2. A tube through which steam and water are released into a boiler drum.

BOILER

A closed vessel in which water is heated, steam is generated, steam is superheated, or any combination thereof, under pressure or vacuum by the application of heat from combustible fuels, electricity, or nuclear energy. The term dose not include such facilities of an integral part of a continuous processing unit but does include fired units of heating or vaporizing liquids other than water where these units are separate from processing systems and are complete within themselves.

CALLENDAR AND BARNES' CONTINUOUS-FLOW CALORIMETER

A calorimeter in which the heat to be measured is absorbed by water flowing through a tube at a constant rate, and the quantity of heat is determined by the rate of flow and the temperature difference between water at ends of the tube.
