Question 280Steam Plants - Assistant Engineer

The correct answer is A) dry steam from the steam and water mixture. The purpose of the separating nozzle in the accumulator of a water-tube, coil-type steam generator is to separate the dry steam from the steam and water mixture. This ensures that only dry, high-quality steam is supplied to the downstream components, such as the turbine or other steam-powered equipment. The other options are incorrect because they do not accurately describe the function of the separating nozzle. Option B refers to the separation of condensate from feed water, which is not the purpose of the separating nozzle in the steam generator. Option C describes the separation of superheated steam from saturated steam, which is not the primary function of the separating nozzle. Option D refers to the separation of sludge accumulations from feed water, which is also not the purpose of the separating nozzle in this context.
