Why soot blowing is carried out in the boiler?
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.
What would you do before you start soot blowing?
BOILER SOOT BLOWING PROCEDURE:-
- Open the isolation valve of soot blowing steam line.
- Open drain valve of this line to drain out condensate if any.
- Put the control valve of the line in auto mode to get 12 to 14 kg/cm2 pressure.
- Check all retractable blowers are in withdraw position.
- Increased the draft a little higher.
What is the recommended air pressure for soot blowing the boiler?
135 to 260 psig
Pressure requirements vary greatly from lance to lance. Normal ranges are from 135 to 260 psig at the nozzle of the blower. Pressure is related to the cleaning energy (PIP) required for a given area and cooling requirements.
Why are operating heads of soot blowers automated?
In modern steam generators, automatic routine soot blowing is essential in order to ensure continuing operation, accuracy of control, and reliability of performance. The boiler heating surfaces exposed to combustion gases tend to become coated with soot and ash.
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 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 do you understand by term soot blowing?
: removal of soot deposits on the tubes of a steam generator by a blast of air or steam.
What is automatic feed water regulator?
Automatic feed water regulating apparatus for steam boilers comprising, a ring-shaped tube, a container surrounding a portion of the ringshaped tube and receiving water and steam from the boiler, an evaporable liquid within said ringshaped tube adapted to be heated by the boiler water and the boiler steam present in …
What does it mean when soot is coming out of my exhaust?
If you vehicle is leaving a noticeable black dusty or dark damp patch behind then this may indicate an issue. Along with that if your mileage has taken a slight dip as well as your vehicles power is a definite sign of a problem.
What causes a car engine to suffocate?
In addition to the glitches already cited, your car’s MIL could point to a bad positive crankcase ventilation valve. The PCV valve is part of your emissions control system. When it sticks open, too much air pours into your engine; when contaminants gum it up, your engine suffocates.
Why does my car have a leak in the boost pipe?
Sometimes, leaks in a pipe can happen due to a loose engine mount, which can twist a pipe simply with torque. Although, loss of power is not harmful – except if you are in a race – it can become harmful if neglected for a long time. Ignoring a boost leak will eventually reduce your turbo’s life and in turn the car engine’s life.
What causes a car engine to lose power?
An air-fuel mix that is too thin to burn could mean a gunked-up fuel injector, an air leak, a weak fuel pump, a choked-off filter or a compromised pressure regulator. It’s also possible, though less common, for the mix to be too rich (which we mentioned before), but this will tend to affect all the cylinders, not just one [sources: B&B; O’Reilly ].
Why is my car blowing white smoke and losing power?
Also, a dirty fuel filter is a common reason why your car is blowing white smoke and losing power. The dirt in the cylinders is burned along with the fuel and this causes smoke to come out of the exhaust. When your car is losing power, it is important you look at other symptoms.

Why does my car lose power when I start it?
Fuel injector problems. Your car may lose power if an injector has poor contact with the internal combustion engine. If this is the cause of the problem, you may also notice an exaggerated vibration in the motor. The fuel injector is an appropriate name for a car part which injects fuel into the engine.
What causes a car to be starved for fuel?
Starved for fuel: This may be caused by a restricted or a wrong fuel filter, air being introduced into fuel system via porous fuel line, loose connection, weak lift pump is so equipped, etc. Restricted air intake: This could be caused by a dirty, incorrect, or collapsing air filter inlet ducting.
