What is the basis on principle of automatic control of combustion is d

1.	What is the basis on principle of automatic control of combustion is determined?(a) Control of fuel supply to the boiler(b) Speed of rotation of fans(c) Control of combustion(d) Control of steam pressureI have been asked this question during an interview.My question comes from Principle of Automatic Control of Combustion in chapter Steam Power Plant of Energy Engineering
Answer» The CORRECT choice is (c) Control of combustion Explanation: The principle of automatic control of combustion is derived from the control of combustion.In order to ensure sufficient AMOUNT of steam GENERATION at the requisite pressure and to maintain correct PROPORTION of fuel and air in a furnace for complete combustion, control of combustion in the furnace is very MUCH essential.
