Understanding How Water is Pumped into a Boiler

The question asks about the specific component used for pumping water into a boiler. In a power plant or industrial setup, water needs to be fed into the boiler at high pressure to be converted into steam. This task requires a dedicated pump.

Analyzing the Options for Pumping Water into a Boiler

Let's look at the given options and determine their functions:

• Rotor: A rotor is a rotating component of a machine, such as a motor, turbine, or pump. While a pump has a rotor, "rotor" itself is not the name of the component that pumps water into a boiler.
• Feed pump: A feed pump, specifically a boiler feed pump, is a type of pump used to supply feedwater to a boiler. This feedwater is then heated and converted into steam. This option directly describes the required function for a boiler.
• Duplex pump: A duplex pump is a positive displacement pump that uses two pumping chambers or cylinders. While a duplex pump *could* be used as a feed pump in some systems, the term "Feed pump" is the more specific and general term for the component performing the function of pumping water into a boiler.
• Economiser: An economiser is a heat exchanger device used to preheat the feedwater before it enters the boiler. This improves efficiency by recovering waste heat from the flue gases. An economiser does not pump water; it heats it.

Identifying the Correct Component: Boiler Feed Pump

Based on the analysis, the component specifically designed and used for the critical task of pumping water into a boiler is the Feed pump. It is a vital part of the boiler system, ensuring a continuous supply of water is maintained at the required pressure.
