What is calorific value of fuel?
The heat value of a fuel is the amount of heat released during its combustion. Also referred to as energy or calorific value, heat value is a measure of a fuel’s energy density, and is expressed in energy (joules) per specified amount (e.g. kilograms). Heat value. Hydrogen (H2) 120-142 MJ/kg.
Which gaseous fuel has highest calorific value?
Hydrogen
Detailed Solution The correct answer is Hydrogen. Hydrogen has the highest calorific value among the following gases. Calorific value is the amount of heat energy present in food or fuel and is determined by the complete combustion of a specified quantity at constant pressure and in normal conditions.
Which fuel has lowest calorific value?
Coal has the lowest calorific value.
What is the calorific value of CNG?
Lower Calorific Value (or Net Calorific Value – NCV, or Lower Heating Value – LHV) – the products of combustion contains the water vapor and that the heat in the water vapor is not recovered….Fuel Calorific Values.
| Natural gas | 12500 kcal/kg |
|---|---|
| Brown coal | 3500 kcal/kg |
| Woods | 2500 kcal/kg |
| Electricity | 860 kcal/kWh |
Which fuel has highest and lowest calorific value?
Calorific value refers to the amount of heat produced when 1 gram of a fuel undergoes complete combustion with oxygen. Its SI unit is kJ/kg. Wood has the lowest (17kJ/g) and kerosene has the highest (48kJ/g) calorific value, among the given fuels.
What is calorific value of diesel?
The Typical Gross calorific value of Diesel or HSD is 10800 Kcal/kg.
What is the calorific value of LPG?
b “The calorific value of LPG is 55000 kJ/kg”.
What is calorific value of coal?
The calorific value of coal is in the range of 25–35 MJ/kg. There are three main types of coal: lignite, bituminous coal and anthracite. Anthracite is the highest quality coal, as it has a carbon content of more than 90% and the highest calorific value.
What is the calorific value of CNG gas?
The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” (standard) conditions (i.e. to 0oC and under a pressure of 1,013 mbar)….Fuel Calorific Values.
