AI Explanation
The correct answer is C) explosions in the boiler furnace.
The primary function of a flame safeguard system on an automatically fired auxiliary boiler is to prevent explosions in the boiler furnace. The flame safeguard system is designed to detect the presence of a flame and quickly shut off the fuel supply if the flame is extinguished. This prevents the buildup of unburned fuel in the furnace, which could lead to an explosion.
The other answer choices are incorrect because they do not accurately describe the primary function of the flame safeguard system. Option A is incorrect because the system is not primarily intended to prevent dry firing or overpressure. Option B is incorrect because the system is not designed to prevent uncontrolled fires in the furnace, but rather to prevent explosions. Option D is incorrect because the system is not primarily intended to prevent overheating of the pressure parts.
