How do water tube boilers handle high pressure and temperature?

Water tube boilers are designed to handle high pressure and temperature by using a system of tubes that can withstand the stresses of high-pressure steam generation. The tubes are typically made of durable materials, such as stainless steel or alloy steel, and are arranged in a way that allows for efficient heat transfer and stress distribution. Additionally, water tube boilers often incorporate features like membrane walls, headers, and drums to manage pressure and temperature fluctuations.
