fuels ã¢â‚¬â€œ calorific value of fuels

Nutritional value of foods, and the usefulness of fuels is determined by the heat (energy) they produce on heating. The energy released by the combustion of foods or fuels is usually compared in terms of their combustion energy per gram. It is known as calor..

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 ..

High calorific value Clean fuel No residue produced No smoke produced Non polluting Economical Can be supplied through pipe lines Burns readily - has a convenient ignition temperatur..

E.g., Water gas and producer gas from coke, coal gas from coal, Bio gas from animal dung, coke from coal, petrol, kerosine, diesel and furnace oil from petroleum, charcoal from wood Moreover different fuels give different amounts of heat on burning. The heat liberated in joules ..

In a test conducted on two rocket engines for 2 hrs, on an average one rocket consumed 2,000 lbs of fuel with a deviation of 200 lbs for every 15 seconds and another consumed 1,500 lbs with a deviation of 300 lbs for every 10 seconds. Find the test value and check whether both t..

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, ..

The bonds between carbon and hydrogen are broken down with the help of oxygen to give energy (oxidation). Carbohydrates produce 4.1kcal/g energy under laboratory conditions. This is called calorific value . However, in the body they produce 4kcal/g of energy. This is called p..

C - H bonds and two O = O bonds are broken to form 2C = O and 4 O - H bonds. Energy required to break C - H bond is 4.5 KJ/mole and that of O = O bond is 497 KJ/mole. Energy released in the formation of O - H bond is 467.25 KJ/mole and that of C = O bonds is 803.33 KJ/mole. So the above reaction ..

). The black residue left in the 1 s t tube is called coke. Coke is a fuel in its own right which can be used in homes and factories. But it is largely used as a reducing agent in the extraction of metals from their ores. It is also used in making fuel gases like water gas which..
