2020-4-22 · 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. Various types of soot blowers such a wall blowers, long retractable blowers and air heater blowers are used for cleaning. Steam is normally used as a medium for blowing away the soot.

2020-5-9 · Soot is a fact of life for those of us who operate a gas- or oil-burning boiler. A little bit of soot is normal, but excessive soot production could indicate a problem with the way your boiler is operating. Large amounts of soot inhibit heat transfer, which forces your boiler to work harder than it

Boiler Uptake Fire and Exhaust Gas Economiser Fi

But when the soot gets wet with hydrocarbon vapours, their ignition temperature comes down to around 150 degree Celsius. This may result in boiler soot fire or boiler uptake fire. When an uptake fire is suspected, never soot blow the economiser. Soot blow with steam causes steam to convert as hydrogen gas and result in metal fire. Preventive

2020-5-1 · Tube cleaning is done periodically to remove the ash or soot deposits. Steam is the medium used for cleaning. The steam is taken from the boiler itself. The soot blower consists of a lance tube with a nozzle at the end. When it is operated, the lance is extended into the boiler and steam is admitted through the lance.

2020-5-8 · Other Soot Blowing Operational Considerations: Tube Erosion. When steam is used as a cleaning medium and a soot blower starts is blowing cycle, there normally is a temperature differential between the soot blower and the steam. When this happens, steam condenses and slugs of water are ejected from the soot blower nozzle.
