Option 2 : Steam boiler

Explanation:

Steam power plant:

  • Steam power plants are widely utilized throughout the world for electricity generation, and coal is often used to fuel these plants.
  • ​A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries.
  • The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy.

Fire Tube boiler:

  • In this boiler, the hot flue gases are present inside the tubes and water surrounds them and sometimes around the outside of the tubes.
  • Hence we can say that they are internally as well as externally fired boilers.
  • They are low-pressure boilers. The operating pressure is about 25 bar.
  • Externally fired fire tube boilers are locomotive type boilers, horizontal return tubular (HRT) boiler, etc.
  • Internally fired fire tube boilers are Scotch-marine boilers, Cochran boiler, package boilers, etc. 

Water Tube Boiler:

  • In this boiler, the water is present inside the tubes and the hot flue gases surround them.
  • They are high-pressure boilers and the operating pressure is about 250 bar.
  • Water-tube boilers are always externally fired.
  • Stirling Boiler, La-Mont Boiler, Benson Boiler, Yarrow Boiler, Babcock and Wilcox Boilers are water tube boilers

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since.  S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
