Most sites have a pipe network supplying steam at three or more pressure levels for different pro-cess uses. A typical steam system is illustrated inFigure 3.2. Boiler feed water at high pressure is preheated and fed to boilers where high pressure steam is raised
2019/8/30 · The working of the Locomotive fire tube boiler is shown in the figure below. Locomotive boiler. The heat of flue gases gets transmitted to the water surrounded. The heated water gets evaporated and converted into steam which is collected in the hemispherical shell.
Water and steam are kept in the same vessel; so, because the fire tubes are trying to heat a vessel full of water, it takes longer to bring the water to temperature. The biggest disadvantage, however, is the possibility of drum (vessel) failure and a huge explosion.
Introduction to Steam Distribution. The steam distribution system is the essential link between the steam generator and the steam user. This Module will look at methods of carrying steam from a central source to the point of use. The central source might be a boiler house or the discharge from a co-generation …
2021/3/2 · The steam boiler also known as the steam generator is, usually a closed vessel made up of steel. In a steam boiler, the water is converted into steam by the application of heat. Fuels, which are commonly used in boilers, are coal, oil, and gas for producing heat.

Design of Cochran Boiler: It is a Fire tube, Stationary, Multi-tubular, Internally fired, vertical boiler. Cochran boiler is made in many sizes capable of producing steam upto 3 T/hour and working pressures upto 17 bar. This boiler gives Thermal efficiency (ƞ th) of 70% with coal firing and about 75% with oil firing.
Steam Boiler: Types and Designs - Certified Commercial Property
When the Valve on the steam pipe serving an item of steam using plant is opened, steam flowing from the distribution system enters the plant and again comes into contact with cooler surfaces. The steam then transfers its energy in warming up the equipment and product (starting load), and, when up to temperature, continues to transfer heat to the process (running load).
2019/1/8 · Fire Tube Boiler: In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam …
