Question

How can be the plant efficiency of steam power plant is increased?

(a) By using high pressure and high temperature steam

(b) By equipping ash and flue gas clearance system

(c) By maintaining the boiler on daily basis by cleaning the soot and combustion products

(d) By using better and efficient type of fuel for combustion

The question was posed to me by my college professor while I was bunking the class.

The doubt is from Function of Boilers in portion Steam Generators & Accessories of Energy Engineering

Answer 1

The correct choice is (a) By using high pressure and high temperature steam

Explanation: The plant efficiency can be increased by using high pressure and high temperature steam. This also reduces the cost of electricity production. The development of newer materials permitted the use of higher operating pressure and temperature of the boiler.
