Boiler draught: primary objectives of producing draught List the functions served by draught in a steam generator, from air supply to gas discharge. Choose the correct option.

Difficulty: Easy

Provide adequate air for complete combustion of fuel
Exhaust hot gases from the combustion chamber
Discharge flue gases to the atmosphere via the chimney
All of the above

Correct Answer: All of the above

Explanation:

ConceptDraught (natural via chimney or mechanical via fans/steam jet) creates the pressure differential to: • Supply sufficient combustion air, • Carry products of combustion through the passes, and • Discharge them safely to atmosphere.

Final AnswerAll of the above
