Gaseous fuels due to their advantages ov...

Gaseous fuels due to their advantages over other types of fuels are becoming highly popular . The advantages of the gaseous fuels are as follows :
a. High calorific value .
b. Do not produce smoke and do not leave ash after combstion .
c. They can flow through pipes and can be ignite at a moment's notice at any place . No special devices are required for their combustion .
i. Coal gas is a good gaseous fuel as it conitains `95%` combustible gaseous such as `H_2, CH_4, CO` etc , It is obtained buy destructive distillation of coal at ` 100^@ C` .
ii. Water gas is a mixture of ` CO` and `H_2` and is prepared by passing steam over incandescnt coke . The reaction is however endothermic .
iii. Producer gas , which possesses low calorific value, so prepared by passing air over red hot coke . It contains mainly nitrogen and ` CO`
iv. Semi-water gas is a mixture of water gas and producer gas .
v. oil gas , which is used in laboratories , is obtained by cracking of kerosene . It is a mixture of hydrocarbon (saturated and unsatureated ) mainly lower hydrocarons .
iv. `LPG`, which contains ` C_3` and ` C_4` hydrocarbon of the alkane and alkene series , supplied in cylinders for domestic uses is very popular these days .

A

Charcoal

B

Kerosene

C
