Steam Boilers and Engines
The ratio of the energy required to produce the artificial draught (expressed in metres head or J/kg of flue gas) to the mechanical equivalent of extra heat carried away per kg of flue gases due to natural draught, is known as
efficiency of the boiler
efficiency of the chimney
efficiency of the fan
power of the boiler
Correct Answer:
efficiency of the chimney

Steam Boilers and Engines
Which of the following statement is correct?
A condenser maintains a low pressure (below atmospheric) so as to obtain the maximum possible energy from steam and thus to secure a high efficiency.
The crown of the fire box is made hemispherical in order to resist intense heat in the fire box.
The indicated thermal efficiency is defined as the
A device used to empty the boiler whenever required and to discharge the mud, scale or sediments which are accumulated at the bottom of the boiler, is called blow off cock.
In fire tube boilers
The value of diagram factor depends upon
Water tube boilers are
In a Woolf type compound engine, the high pressure and low pressure cylinders
The boiler efficiency is given by (where m = Total mass of water evaporated into steam in kg/h, mf = Mass of fuel in kg/h, C = Calorific valve of fuel in kJ/kg of fuel, h = Total heat of steam in kJ/kg, and hf1 = Sensible heat of feed water in kJ /kg)
