How do you find the calorific value of a fuel?

Goutel suggested the following formula from calculating the higher calorific value when the percentage proximate analysis of fuel is known. The formula is, cal. value = 343.3 x fixed carbon \% + α x \% volatile matter kJ/kg.

What are the methods for determination of calorific value of any solid fuel?

The calorific value can be determined either from chemical analysis by Dulong�s formula or in the laboratory by any experimental method. Where C, H, O and S are carbon, hydrogen, oxygen and sulphur in percentage constituents respectively in 1 kg of fuel.

How do you find the calorific value of a solid fuel and a liquid fuel?

From the observed rise of temperature of the water and the container the calorific value of the fuel can be determined by equating the heat given out by the fuel to the heat taken by the water and the container. In order to know the heat taken by the container, water equivalent of the container should be known.

What are the instruments to check the calorific value of liquid and solid fuels?

There are two basic types of calorimeters: a steady-flow calorimeter to measure the heating value of gaseous fuels and the bomb calorimeter (constant-volume) for use with liquid and solid fuels.

How do you calculate the calorific value of a fuel class 8?

What is called calorific value discuss the method used for the determination of calorific value?

The calorific value of fuel can be defined as the amount of heat produced by the complete combustion of one unit of any fuel. The unit depends upon the type of fuel, for example, coal is a solid fuel so it is measured in weight units whereas we use volume units for any gaseous or liquid fuel.

How do you find the calorific value of fuel class 8?

The calorific value of a fuel is expressed in the unit of Kilojoules per kilogram. For Ex:The calorific value of kerosene is 45000KJ/Kg means when 1Kg of kerosene is burned completely then 45000 KJ of heat energy is produced.

What is calorific value of fuel class 8?

The amount of heat produced by the complete burning or combustion of 1Kilogram of a fuel is called its calorific value.

How do you calculate calorific value of fuel?

Gross calorific value (GCV) and net calorific value (NCV) are the terms used in the formula to calculate calorific value of fuel. Latent heat escaped (in form of water vapor) is subtracted from the Gross calorific value to get the Net calorific value.

How to calculate the water equivalent (m) of the bomb and calorimeter?

In order to find out the water equivalent (m) of the bomb and the calorimeter, chemical compounds of known calorific values are taken. The following are the compounds generally used: (i) Naphthalene- Calorific value = 40.57 MJ/kg (ii) Benzoic acid- Calorific value = 26.489 MJ/kg

What is lower calorific value (LCV) of fuel?

We can subtract from the hcv, an amount of heat required to evaporate the water formed, we can easily find Lower Calorific Value (LCV). Besides, we also know it as Net Calorific Value (LCV) i.e. Net Calorific Value of the fuel. There is no definite agreement in the literature is available on fuel.

What is a fuel calorimeter?

An apparatus which is used for determining the calorific value of a fuel is known as a fuel calorimeter. The principle of all the calorimeters is the transference of heat of combustion of the given weight of fuel to water and the vessel.
