The boilers are fitted with different safeties as the steam pressure is up to 8 bars in most cases. There are normally two kinds of boilers on ships, Auxiliary and Exhaust, some ships have composite boilers. Boiler are of two type. STB (Smoke tube Boiler) or donkey boiler; WTB (Water tube Boiler) or High pressure boiler

CHAPTER 4 BOILERS The function of a boiler in the steam cycle is to convert water into steam. Reliability in operating naval boilers and associated equipment is important for the power plant to operate at maximum efficiency. The complex design of naval boilers requires a high degree of technical knowledge and skill on the part of the fireroom personnel responsible for boiler operations.

Boiler Basics Design and operation A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat for the steam requirements of process industries or for power generation.

Steam boilers provide efficient heat for homes and industrial settings. In most cases, raw water is fed into the boiler from a pipe system. That water is then purified to clean it of any debris. Next, the water is fed into a de-aerator that removes air, then is fed into the boiler tank and heated.

Steam Power Cycle and Basics of Boiler 1. THERMAL POWER PLANT by: Mulugeta T. 1 2. CHAPTER-2: 2. Analysis of Steam Cycles 2.1 Introduction • A steam power plant continuously converts the energy stored fossil fuels (coal, petroleum, and natural gas ) or fissile fuels (uranium, thorium) OR other energy resources in to shaft work and ultimately into electricity.
Get A QuoteThe steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.

traps at natural low points or ahead of control valves. In the heat exchangers, traps perform the vital function of removing the condensate before it becomes a barrier to heat transfer. Hot condensate is returned through the traps to the boiler for reuse. Figure CG-5. Coil half full of condensate can't work at full capacity. Figure CG-4.

In addition, boilers that are built to produce superheated steam require more expensive components on the boiler system, in comparison to a saturated steam boiler. Therefore, it is extremely important to do your homework ahead of time to determine which type of steam is best suited for your particular application.
