Final answer:
The highest part of the steam side of the drum is known as the steam cap. This area collects the high-quality steam before it exits the boiler. The heat absorbed by steam when heated can be calculated with the specific heat formula.
Step-by-step explanation:
The highest part of the steam side of the drum is known as the steam cap. The term steam cap refers to the area in a steam drum where the highest quality and temperature of steam is collected before it exits the boiler and heads towards the steam turbine or other usage points.
The exact name can vary depending on the design and terminology used by different manufacturers and engineers, but steam cap is a term that is sometimes used in this context.
Understanding the properties and behavior of steam in a boiler is essential for efficient energy generation and usage. When steam is heated from 100°C to 140°C, the heat absorbed is calculated using the formula ΔH = Cp × m × ΔT, where ΔH is the change in enthalpy, Cp is the specific heat of steam at constant pressure, m is the mass of the steam, and ΔT is the change in temperature.
