What is L.P.G. ? Why is it called a good fuel ? |
|
Answer» Solution :The petroleum gas liquefied under pressure is called liquefied petroleum gas (L.P.G.) It consists mainly of butane with small amounts of propane and ethane. This is the domestic gas that we use. The gas used for domestic cooking PURPOSES is called Liquiefied Petroleum Gas. (L.P.G.) because it is obtained from petroleum and it is liquefied by compression before filling in cylinders. Uses of L.P.G. The L.P.G. is mainly used for domestic heating purposes. It is obtained in cylinders. When we turn the knob of the gas cylinder, the pressure is released resulting in decrease of pressure inside the cylinder so that highly volatile L.P.G. changes into gas. The gasflows to the burner of the cooking STOVE. When ignited, the gas BURNS with a blue flame producing a lot of heat. This heat is used for cooking our food. Advantages of L.P.G. Liquid petroleum gas is CONSIDERED to be a good FUEL because of the following reasons : 1. L.P.G. has a high calorific value. Its calorific value is about 50 kJ/g. This means that when 1 gram of L.P.G. burns in a gas stove, it produces about 50 kJ of heat energy. Therefore, it has higher efficiency as a fuel. 2. It is very neat and clean domestic fuel it burns with a smokeless flame and so does not cause pollution. 3. It does not produce any poisonous gases on burning. 4. L.P.G. is easy to handleand it it convenient to store. 5. It undergoes complete combustion. |
