What are the characteristics and methods for measuring calorific values of fuels?
Understand the Problem
The question appears to be related to the characteristics and measurement of fuels and calorific values, potentially asking about specific concepts or definitions within that context.
Answer
Calorific value is measured using a bomb calorimeter by combusting fuel with oxygen to find GCV and NCV.
The characteristics of fuels regarding calorific values include energy content and combustion efficiency. These are measured using a calorimeter, often a bomb calorimeter, which combusts the fuel in oxygen to determine the heat released. The main calorific values calculated are the Gross Calorific Value (GCV) and the Net Calorific Value (NCV).

More Information
The calorific value is crucial as it helps in understanding the efficiency and heat output of fuels. The bomb calorimeter is a standard, reliable method that helps ensure consistency in these measurements.
Tips
Common mistakes include not accounting for heat losses in the calorimeter or misunderstanding the distinction between GCV and NCV.
