The correct answer is C) reduce the possibility of carryover. Steam baffles in the steam drum of a water-tube boiler are designed to reduce the likelihood of water droplets (carryover) being transported from the steam drum into the steam supply. This helps maintain the purity of the steam and prevents potential damage to downstream equipment. The baffles create a change in the flow of steam, causing water droplets to be separated and returned to the boiler water. The other options are incorrect because they do not accurately describe the primary function of steam baffles in a water-tube boiler. Option A refers to the feed pipe, which is a separate component. Option B is about removing dirt deposits, which is not the main purpose of steam baffles. Option D is about supporting the safety valve, which is also unrelated to the primary role of steam baffles.
