1.The equivalent evaporation of a boiler is a measure to compare

the given boiler with the model
the two different boilers of the same make
two different makes of boilers operating under the same operating conditions
two boilers of same make but operaing under different conditions
any type of boilers operating under any conditions.

2.Coke is produced by

pulverising coal in inert atmosphere
heating wood in a limited supply of air at temperatures below 300GC
strongly heating coal continuously for about 48 hours in the absence of air in a closed vessel
binding the pulverised coal into bricketts
enriching carbon in the coal.

3.Stoichiometric quantity of air is the

air present in atmosphere at NTP conditions
air required for complete combustion of fuel with no excess air
air required for optimum combustion so as to have reasonable excess air
air required to convert CO into C02
air required to form an explosive mixture.

4.Equivalent evaporation is the amount of water evaporated in a boiler from and at

0�C
