Ekgas here’s a clear and useful explanation of Combustion, suitable for general understanding or industrial context:

What Is Combustion?

Combustion is a chemical process in which a fuel reacts with oxygen to release heat, light, and various reaction products. It is one of the most common energy-producing processes in industrial, commercial, and everyday applications.

How Combustion Works (Simple Explanation)

1. Fuel + Oxygen → Heat + Products

2. The fuel may be:

   • Gas (natural gas, LPG, hydrogen)

   • Liquid (diesel, oil)

   • Solid (coal, biomass)

3. When the mixture is ignited and conditions are right, the reaction becomes self-sustaining.

Key Requirements for Combustion

Often called the Combustion Triangle:

1. Fuel

2. Oxygen (usually air)

3. Ignition source (spark, flame, heat)

Remove one of these three, and combustion stops.

Types of Combustion

1. Complete Combustion

• Fuel burns with enough oxygen.

• Produces CO₂ + H₂O.

• High efficiency, clean flame.

2. Incomplete Combustion

• Not enough oxygen.

• Produces CO, soot, unburned hydrocarbons.

• Wastes energy and increases pollution.

3. Industrial High-Temperature Combustion

• Used in:

  • Furnaces

  • Boilers

  • Industrial burners

  • Thermal energy equipment

Where Combustion Is Used

• Industrial burners (metallurgy, ceramics, food processing)

• Boilers and steam generation

• Heating systems

• Power plants

• Engines and turbines

Important Combustion Control Elements

• Burner design

• Air-fuel ratio control

• Gas regulator

• Solenoid valves

• Controllers & sensors

• Safety systems (flame detectors, relief valves)

Proper control ensures:
✔ High efficiency
✔ Low emissions
✔ Safe operation
