Which boiler type requires a super heater?

• A. A power boiler
• B. A residential boiler
• C. A coastal boiler
• D. A compact boiler

Answer: (A)

A superheater is used to heat steam beyond the saturation point, producing dry, high-temperature steam that can drive turbines efficiently. In power generation, the boiler’s job is to generate steam at high pressure and temperature for a turbine. To achieve the necessary high temperature and keep the steam dry during expansion, the steam is routed through a superheater after leaving the boiler. That makes a power boiler the type that requires a superheater. Residential boilers are designed for heating buildings and typically produce low-pressure steam or hot water, so they don’t need the extra heating stage. The terms coastal and compact boiler don’t inherently imply the need for superheating; they refer to other design or size considerations, not the requirement for turbine-grade, superheated steam.
