Category: Steam Condensers

In evaporative condenser, steam circulates in pipes surrounded by water spray, as shown in Fig. 8.9. It is used when there is scarcity of cooling water. The cooling water is allowed to evaporate under a small partial pressure. It consists of gilled piping bent to form many rows and is placed vertically. Steam passes through these pipes.…

In such a condenser as shown in Fig. 8.8, the steam passages are all around the periphery of the shell. The exhaust steam converges to the centre of the shell where there are no tubes. The air is removed by the air pump suction from the centre. Some of the exhaust steam also passes to the…

2 Surface Condensers Water Tube Surface Condenser In this type of surface condenser, water flows in the tubes and steam surrounds it. Thus, the condensate is directly available as an ideal boiler feed. A surface condenser produces more vacuum and any type of cooling water can be used. However, it is bulky and the initial…

Steam condensers may be broadly classified into two categories.

A steam power plant using a condenser is shown in Fig. 8.2. The various components of a steam condensing plant are described below. Figure 8.2 Steam power plant using a condenser

There are two main functions of a condenser, which are explained below: Figure 8.1 Effect of back pressure on work output of a steam engine

A condenser is a closed vessel in which steam is condensed by abstracting the heat and where the pressure is maintained below atmospheric pressure.
