This document summarizes different types of fuels including solids, liquids, gases, electricity, and steam. Solid fuels like coal have low production costs but high ash content and handling costs. Liquid fuels such as diesel and petrol can be easily controlled but are more expensive. Gaseous fuels like liquefied petroleum gas can be conveyed through pipelines and lit on demand but require large storage tanks. Electricity allows for easy heat control and adjustment without storage, but electric burners produce less heat than gas burners. Steam provides uniform and controllable heating and quicker heating of stock pots compared to those on a range or stovetop.

1. FUEL TYPES

2. INTRODUCTION
• Fuel is a substance which produces a
large amount of heat when burnt with
oxygen of atmospheric air.
• Fuels are primarily used for heating
purposes.

3. Fuels are available in the form of
• Solids
• Liquids
• Gases
• Electrcity
• Steam

4. SOLID FUELS
• Solid fuels are coal,firewood,dung,wood charcoal.
Advantages
• They are easy to transport.
• Their cost of production is low
Disadvantages
• Their ash content is high
• They burn with clinker form
• Their cost of handling is high

5. LIQUID FUELS
• Liquid fuel are kerosene,diesel,petrol,furnace oil.
Advantages
• Their flame can be controlled.
• They are clean in operation.
• They burnt with out forming ash.
Disadvantages
• The cost is high
• They give bad odour
• Costly special storage tanks are needed.

6. GASES
• Gases fuels are liquified
petroleum,biogas,producer gas.
Advantages
• They can be easily conveyed through pipelines.
• They can be lighted at any moment.
• They are clean in use
Disadvantages of gaseous fuels
• Very large storage tanks are neded.
• Highly inflammable
• Costly.

7. ELECTRICITY
Advantages
• Easily controlable
• Heat adjustment is very easy
• No storage is needed
Disadvantages
• A gas burner can produes more haet than a
electric burner
• Power cut interruptions are there
• Installation cost is higher

8. STEAM
• Steam jacketed kettles are some times though
of has stock pots that are heated not just on the
bottom but on the sides as well.
• The comparison is only partly accurate.
• Steam kettles heat much more quickly and
have more uniform and controlable heat than
pots on the range.
