The amount of water evaporated in kg per kg of fuel burnt in a boiler is called the ______________ of a boiler ?
Correct answer: A. Evaporative capacity
- A. Evaporative capacity
- B. Evaporation efficiency
- C. Thermal efficiency
- D. Steam load
Explanation
Evaporative capacity is the mass of water converted into steam per unit mass of fuel burned, usually expressed as kg/kg of fuel. Thermal efficiency is instead the ratio of useful heat output to heat supplied by the fuel.
