Biomass fuels
These are material contained in the bodies of plants, and animals, which can be used as a fuel or act as a source of fuel. Typical examples of Biomass are, wood, animal dung, agricultural waste (such as, baggasse), wild grass and plants etc. Biomass is a con..
Biomass as a Fuel - Biogas
Biogas is a clean and efficient fuel. It is a mixture of methane (CH 4 ), carbon dioxide (CO 2 ), hydrogen (H 2 ) and hydrogen sulphide (H 2 S). The chief constituent of biogas is methane (65%..
As a fuel
Hydrogen has a high calorific value, and as such, is an ideal fuel. It has a high calorific value. It is also 100% pollution free, as the only product formed on combustion is water vapour. Many gaseous fuels such as, water gas, coal gas, etc. contain comparatively high percenta..
Advantages of liquid and gaseous fuels over solid fuels
Unlike solid fuels liquids and gaseous fuels leave behind no ash. They have low ignition temperature compared to solid fuels. The calorific value of liquid and gaseous fuels is higher and can be easily transported through pipelines. They ..
Bio-mass
BIO-MASS Given the large live-stock population in India, we can use this fuel as a steady source. These fuels are obtained from plant and animal produces, so it is called bio-mass. Cow-dung, various plant materials like the residue after harvesting the crops, vegetable was..
Fossil Fuels

Densities of Liquids
Water is the most common liquid. Density of water at 4 o C is 1 g cm - 3 (1000 kg m - 3 ). Example : 28 kg of fuel completely fills a 40 liter petrol tank of a vehicle. What is the density of the fuel? (1 liter = 10 - 3 m 3 ) Suggested Answer : Mass o..

Management of fossil fuels
India produces only half of the national requirement of petroleum products and it imports the rest from other countries. Natural gas is the most popular petroleum product. During last two decades, the consumption of natural gas resources have increased tenfold. If we need to save fossil fuelsh..
Compressed natural gas (CNG) and Liquid natural gas (LNG)
A liquefied form of natural gas usually consists primarily of methane. Its properties are those of liquid methane, slightly modified by minor constituents. One property, which differentiates liquefied natural gas (LNG) from liquefied petroleum gas (LPG), which is principally propane or b..
