Get Hot on Combustion!

Written by Thomas Yoon

Energy inrepparttar form of heat is obtained when fuel is burnt in air. The release of this heat energy can be slow or can be very rapid.

When fuel oil is sprayed as a fine mist inrepparttar 127639 boiler burners, it is able to burn at a relatively slow rate. When fuel is sprayed intorepparttar 127640 cylinders of diesel engines,repparttar 127641 fuel burns in such a rapid rate that explosions occur. Fortunately, these explosions are protected from persons as these engines are called internal combustion engines.

Whatever type of combustion, it is a chemical reaction between carbon, hydrogen, sulphur and oxygen.

C + O2 = CO2 2CO + O2 = 2CO 2H2 + O2 = 2H2O S + O2 = SO2 2S + 3O2 = 2SO3

Air consists of 77% Nitrogen and 23% Oxygen by mass. For a particular design of combustion air,repparttar 127642 theoritical oxygen multiplied by 100/23 will giverepparttar 127643 theoritical air required.

How do you measure a good combustion. The percentage of Oxygen or Carbon Dioxide will tell us whetherrepparttar 127644 combustion is good or not good.

The lowerrepparttar 127645 Oxygen content inrepparttar 127646 exhaust gas,repparttar 127647 betterrepparttar 127648 combustion. It means thatrepparttar 127649 Oxygen has been fully utilized for burning. It also means thatrepparttar 127650 fuel air ratio is set properly. Too much excess air is no good becauserepparttar 127651 heat generated will be lost throughrepparttar 127652 exhaust trunking.

“There is a principle which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance – that principle is contempt prior to investigation. – Herbert Spencer”

Albert Einstein - "We are seeking forrepparttar simplest possible scheme of thought that will bind togetherrepparttar 127638 observed facts."

"If we do not expectrepparttar 127639 unexpected, we will never find it." – Heraclitus

"Human beings, by changingrepparttar 127640 inner attitudes of their minds, can changerepparttar 127641 outer aspects of their lives." - William James

"I feel that if we could be serious for an hour and really fathom, delve into ourselves as much as we can, we should be able to release, not through any action of will, a certain sense of energy that is awake allrepparttar 127642 time, which is beyond thought." – Jiddhu Krishnamurti, Madras, 1961

Heraclitus: "… concededrepparttar 127643 existence of an over-riding, all-encompassing unity, in whichrepparttar 127644 apparently contradictory opposites are all linked to one another, in a single, regular, cohesive system of balanced, harmonious measure and just order."

“Consciousness is a singular of whichrepparttar 127645 plural is unknown. There is only one thing, and that which seems to be a plurality is merely a series of different aspects of this one thing, produced by a deception,repparttar 127646 Indian maya, as in a gallery of mirrors.” – Erwin Schrödinger
