FIRE AS A FRIEND

Fire is the rapid oxidation of a material in the chemical process of combustion, releasing heat, light and various reaction products Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans in rituals, in agriculture for clearing land, for cooking, generating heat and light, for signaling, propulsion purposes, smelting, forging, incineration of waste, cremation etc.

COOKING

Fire is used for cooking. Cooking or cookery is the art, technology and craft of preparing food for consumption with the use of heat. Cooking techniques and ingredients vary widely across the world, from grilling food over an open fire to using electric stoves, to baking in various types of oven, reflecting unique environmental, economic and cultural traditions and trends.

BURNING LAMPS

An oil lamp is an object used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although not commonly anymore. Most such lamps have been replaced by gas-based or petroleum-based fuels to operate when emergency known-electric light is required. As such, oil lamps of today are primarily used for the particular ambiance they produce.

FOR KEEPING WARM

Fire is used to keep the rooms warm using a fireplace. Also logs of are put on fire to keep the people warm outdoors in cold climate areas.

RELIGIOUS PURPOSES

Fire has been an important part of human culture. In Vedic disciplines of Hinduism, fire is a central element in the Yajna ceremony, with Agni , "fire", playing the role as mediator between the worshipper and the other gods.

PROPULSION OF MOTOR VEHICLES/RAIL/SHIPS

Fire is the main component in propulsion of any internal combustion engines. Be it a petrol or a diesel engine the fuel is burnt in a chamber and the pressure generated is converted to movement. In steamer steam is produced by fueling coal and the steam drive the propellers or paddle wheels. Same principle is used in rail engines, where the steam energy is used for moving the piston and thereby rotating the wheels.

GENERATION OF ELECTRICITY

Electricity is generated in large scale in thermal plants. A thermal power station is a power plant in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven. Water is heated using diesel or coal, which turns into steam and spins a steam turbine which drives an electrical generator to produce electricity.

CREMATION

Cremation is the combustion, vaporization and oxidation of dead bodies to basic chemical compounds, such as gases, ashes and mineral fragments. Fire is used for cremation. Cremation helps safe disposal of waste, which are hazardous to health.

SMELTING

Smelting is the process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke.

FORGING

Forging is the making or shaping (a metal object) by heating it in a fire or furnace and hammering it.

INCINERATING

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas, and heat.
