Question 497Steam Plants - Assistant Engineer

The correct answer is B) side water wall header. The side water wall header is a pipe that runs along the side of the boiler and distributes water to the water wall tubes. This component is responsible for supplying water to the water wall, which is a critical part of the boiler's heating system. The side water wall header ensures an even distribution of water throughout the water wall, allowing for efficient heat transfer and steam generation. The other answer choices are incorrect because they do not accurately describe the function of the component labeled "J" in the illustration. A screen tube header, a support beam, and a water drum serve different purposes within a boiler system and are not the correct identification for the component in question.
