A soot blower is a device used to remove soot buildup in boilers or furnaces. It operates by releasing steam or compressed air through nozzles to dislodge the soot from the heating surfaces, helping to improve heat transfer efficiency and prevent potential boiler damage. Soot blowers are typically automated to clean the surfaces at regular intervals without the need for manual intervention.
There could be several reasons why the blower only works some of the time. It could be a faulty blower motor, a problem with the blower motor resistor, a malfunctioning switch or control module, or an issue with the electrical connections or wiring. It's best to have a professional diagnose and fix the problem to ensure the blower works consistently.
Soot particles are lighter than air and rise due to convection currents created by the heat of the fire. As the soot rises, it cools and mixes with air, forming smoke. The smoke is a combination of the soot particles and other gases and particles produced by the combustion process.
A properly functioning Bunsen burner should not produce smoke or soot. It operates by mixing air with a flammable gas to produce a clean, hot flame. If smoke or soot is present, it could indicate inadequate air supply or a problem with the gas mixture.
The blower unit on a High-speed Ribbon Blower typically gets its power from an electric motor. The electric motor drives the impeller inside the blower unit, creating airflow and generating the necessary suction or pressure for the blower to operate efficiently.
When air holes are closed, oxygen supply decreases, leading to incomplete combustion and the production of soot particles. These soot particles can get heated up to incandescence and emit visible light, creating a luminous flame. The presence of carbon in the soot is what causes the flame to appear luminous.
Soot blowing is done in air pre heater by a blower called swing blower which is different from half retractrable or full retractable or deslagger.

Soot blowers are used in boilers to remove accumulated soot and ash from the heat transfer surfaces, which helps maintain optimal heat transfer efficiency. Regular soot removal prevents the formation of insulating layers that can reduce boiler performance and increase fuel consumption. By minimizing soot buildup, soot blowers also aid in preventing overheating and potential damage to boiler components, thereby enhancing overall operational safety and reliability.
Bad blower resistor?
The wiring, switch or blower has failed.
when a blower motor only works on high, it is usually due to faulty resistor board. Should be located in the duct near the blower. the purpose of this is so the air blown by the blower keeps the resistors cool.
The blower may simply have burned out. If the blower is out then the heater probably still works.
The blower motor works on only one speed. The blower motor resitor pack is defective and needs to be replaced. It is located on the blower housing in the engine compartment just below the blower motor.

To remove soot from a smokestack exhaust, you can use mechanical cleaning methods such as scraping or brushing to dislodge accumulated soot. Additionally, installing a soot blower can help remove deposits continuously by using steam or air to dislodge soot while the system is in operation. Regular maintenance and inspection of the exhaust system are crucial to prevent excessive buildup. Chemical cleaners may also be used, but they should be applied with caution to avoid damaging the exhaust components.
