How does a sonic soot blower work?
CLANUS Sonic Soot Blower is based on the principle of kinetic energy activation of the dust particles. The Sound generator sent out powerful sound signals(140 Db) of low frequency (120-240 Hz) and high intensity at suitable intervals. The sound energy vibrates the ash particles and thus tears them away from each other.
What state is the soot blower in when not in use?
7. In which state would be the soot blower when it’s not in use? Explanation: When not in use the soot blower tube of the system would be dry and uncooled, and subject to gas temperatures.
What is retractable soot blower?
A straight-line retractable sootblower is designed for applications where the lance tube is inserted and retracted without rotation. It is used with rake-type lance tube assemblies that reside permanently in the flue gas.
How many types of soot blowers are there?
There are two types of soot blowers. These are rotary soot blowers (RSB) and long retractable soot blowers (LRSB) . Rotary soot blowers rotate at a fixed position. In long retractable soot blowers the lancer enters into flue gas path and also rotates like rotary blowers.
What is the purpose of soot?
Uses. Although a somewhat harmful byproduct of combustion, soot can be used as a pigment for inks and dyes (in fact both lampblack and carbon black are dyes made of soot). Soot is used in a vulcanization process to treat rubber, and is used in toners for laser printers and copiers.
What is the advantage of using a retractable soot blower?
The retractable lance will remove any soot, ash or slug accumulated in the tubes. If these accumulations are not removed, a reduced heat transfer and increase in the tube metal temperatures will occur leading to failure of the tubes. In some instances, the increased metal temperatures can lead to boiler fires.
What is the function of soot?
The soot which sticks to the heating surface insulates them from the heat, efficiency soot must be blow off to maximize heat transfer in the boiler. Elevated stack temperature may indicate excessive soot build up.
What is the function of soot blower?
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.
Is soot harmful to humans?
Soot poses tremendous harms to public health, particularly because of its size. Microscopic particles can penetrate deep into the lungs and have been linked to a wide range of serious health effects, including premature death, heart attacks, and strokes, as well as acute bronchitis and aggravated asthma among children.
What is another word for soot?
What is another word for soot?
What are soot blowers used for?
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)
Why soot blowing is done?
WHY SOOT BLOWING NECESSARY IN BOILER? A soot blower is a system for removing the soot that is deposited on the furnace tube of a boiler during Combustion. The soot which sticks to the heating surface insulates them from the heat, efficiency soot must be blow off to maximize heat transfer in the boiler.
These are designed for soot blowing applications. The sound waves generated by a special bell shaped horn powered by air and controlled electrically by solenoid valve. The kinetic energy imparted to the dust particles cause them to vibrate, break their bonds with other particles and the surface to which they cling.
