Ignition Triangle

Ignition Triangle:

               In chemical point of view, oxidation, combustion and explosion are all exothermic

reactions with different reaction speeds. For such reactions to take place, it is essential that the 

following three components be present simultaneously in due proportions.

• Fuel: flammable vapors, liquids or gases, or combustible dusts or fibers.
• Oxidizer: generally, air or oxygen.
•Heat( Ignition Energy): electrical or thermal heat energy.

Boiler Steam Drum Level Control

• Drum Level Control Systems are used extensively throughout the process industries and the Utilities to control the level of boiling water contained in boiler drums on process plant and help provide a constant supply of steam. 
• If the level is too high, flooding of steam purification equipment can occur. If the level is too low, reduction in efficiency of the treatment and re circulation function. Pressure can also build to dangerous levels. 
• A drum level control system tightly controls the level whatever the disturbances, level change, increase/ decrease of steam demand, feed water flow variations.
