Boiler Soot Blowing Basics

Soot Blower - Auxiliary Boiler on Ships

Between periodic boiler cleaning the gas surfaces of the boiler tubes should be kept as clean as practicable. To facilitate this, soot blower, steam or air operated, are often fitted. They enable the tube surfaces to be cleaned of loose sooty deposits rapidly without shut down of the boiler.

Improving Boiler Efficiency - Chemical Engineering Site

During normal operation effective soot blowing operation is to be carried out to remove the soot's from the surfaces, which influences the boiler efficiency to a great extent. Fuel Quality. Loss of Heat due to Moisture & Ash content in the fuel will decrease the boiler efficiency.

Soot blower - Wikipedia

2019-9-29 · A sootblower is a device for removing the soot that is deposited on the internal furnace tubes of a boiler during combustion to prevent plugging of the gas passes and maintain boiler efficiency. Types of soot blowers: Wall Blowers also known as IRs (Insertable Rotating) Long Retractable Soot Blower (LRSB) or IK (Insertable Kinetic) Air Heater

Combustion Fundamentals - Industrial Wiki - odesie

Good combustion is very rapid, has a high flame temperature, and is very turbulent. Turbulence is a key factor in boiler furnace combustion. If the turbulence is high, the mixing of the oxygen and fuel will be good, therefore, combustion will occur very rapidly and the result will be a high flame temperature. (usually with soot blowing
