Useful power = the power transferred to the boiler from water and steam

Question

BlackTom AI · Accepted Answer

Statement to evaluate: 'Useful power = the power transferred to the boiler from water and steam.'

Option 1 (True): This is incorrect because the useful power of a boiler is not defined as the power transferred to the boiler by the working fluids (water and steam). In a boiler, the primary direction of energy flow is from the heat source into the water to produce steam, i.e., the boiler absorbs heat from a burner or other source and transfers it to the water/steam. Saying that useful power is the power transferred to the boiler from water and steam reverses the direction of energy flow and misidentifies the source of energy.

Other potential perspective on true would require specifying direction of energy transfer, but in standard boiler terminology, the useful power is associated with the energy delivered to the working fluid (water/steam) as heat input, not energy being transferred into the boiler from the fluid.

Option 2 (False): This correctly reflects the common understanding of boiler power terms. The boiler gains energy from the external heat source and transfers that energy to the water/steam to produce steam. The phrase 'power transferred to the boiler from water and steam' implies the opposite flow and is not how boiler power is defined.

In summary, the statement misstates the direction of energy transfer in a boiler system, making the assertion inaccurate. The correct interpretation emphasizes energy input into the water/steam from the external heat source, not energy input into the boiler from the fluids themselves.
