Question

What is the purpose of Automatic combustion control system?

(a) To get constant steam pressure

(b) To maintain steady state combustion

(c) To get constant steam output

(d) To save the time and manual labour

The question was posed to me in homework.

Question is taken from Principle of Automatic Control of Combustion in section Steam Power Plant of Energy Engineering

Answer 1

Correct answer is (b) To maintain steady state combustion

The explanation: The automatic combustion control system provides the effective prevention of the environmental pollution and steady combustion condition to get a constant steam output. But few factors prevent steady combustion condition such as unbalanced combustion air and the movement of the burn-out position in the incinerator.
