What are the basic steps in Boiler Design. Based on the abovementioned definition of a boiler and defining the accessories and mountings of a boiler system, we can now discuss the physical and mechanical principles that a boiler compiles with during its functioning process. Normally a boiler is designed to suit the user’s requirements.

If a power plant able to convert 100% of the chemical energy in the fuel into electricity, the thermal plant would have a heat rate of 860 kcal/kWh. Unfortunately, due to the losses explained above, a modern conventional power plant might have at best a design full load heat rate of the order of 2200 kcal/kWh, which is about 39% efficient.

May 20, 2013 · If a boiler is shut down for cleaning and inspection, it cannot generate steam. It may be extremely reliable, but it is unavailable the week it is shut down.

A 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 generator.

The first part of the conversion is efficiency of the boiler and combustion. For this example we take 88 % on an HHV basis that is the normal range for a well-optimized power plant. Second part is the steam cycle efficiency. Modern Rankine cycle, adopted in coal fired power plants, have efficiencies that vary from 32 % to 42 %.
