In fossil-fuel power plants (coal, oil, or biomass) and industrial process heaters, combustion produces byproducts. If these byproducts accumulate on tubes and walls, they act as insulators. This reduces heat transfer efficiency, raises stack temperatures, and can lead to costly shutdowns. The sootblower is the primary cleaning agent used while the unit is online.
| Problem | Symptom | Consequence | | :--- | :--- | :--- | | | Blower gets stuck in the boiler | Catastrophic tube damage, forced outage | | Nozzle erosion | Poor cleaning; ash islands on tubes | Efficiency drop, adjacent tube erosion | | Valve leaks | Steam hissing when blower is idle | Energy waste, localized tube erosion | | Carriage drive slip | Inconsistent travel speed | Uneven cleaning, lance vibration | | Limit switch failure | Blower over-travels or parks wrong | Mechanical damage, steam waste | sootblower
There are several types of sootblowers available, each designed to cater to specific boiler configurations and operational requirements. The most common types of sootblowers include: In fossil-fuel power plants (coal, oil, or biomass)
Quick bursts (10-30 seconds) at regular intervals. The sootblower is the primary cleaning agent used
