The condenser is a heat exchanger which removes the latent heat from exhaust steam so that it condenses and can be pumped back into the boiler. The feed system completes the cycle between boiler and turbine to enable the exhausted steam to return to the boiler as feedwater.

There is a tremendous variation in boiler design and size- ranging from home heating size of capacity less than 100 Ibm/hr of steam to utility boilers in excess of 10 million Ibm/hr. The focus here will be on boilers sized in between these two extremes, which is also where there is the greatest diversity of design.

Mar 03, 2021 · High pressure steam boiler stack temperatures often range from 400 degrees F to 650 degrees F. That high temperature exhaust is wasting energy. That is where boiler economizers come in to reduce that heat loss. Remember, we need a fluid that can use the heat AND is at a lower temperature than the flue gas. Dry Economizer

Jul 29, 2009 · A basic boiler is a machine with the simplest arrangement of the internal parts. The main job of a boiler is to make high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure.

What is Steam Boiler? A steam boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam …

By the use of feed-heating, a certain percentage of this heat in the ex haust steam may be recovered and returned to the boiler in the form of heat in the feed-water. Likewise, the waste heat in the cinders and gases passing through the smoke-box, and out of the stack, may be partially recovered, by utilization in an econo mizer for further
