and avoids forced outages due to soot accumulation. Fig 1.1: Actual image of LRSB inside the boiler The basic principle of long retractable soot blowers is to periodically keep cleaning the multi surface tube banks by high impact of air, steam or water through the nozzle attached in LRSB through transverse as well rotary motion.

Soot Blowers - an overview | ScienceDirect Topics

Steam Soot-blowers. Soot blowing is most commonly carried out using dry saturated or slightly superheated steam at boiler pressure. The use of dry saturated steam generally has a better impact effect in removing deposits than superheated steam, but precautions must be taken to preclude slugs of water from entering the boiler flueways.

US20110203535A1 - Method and System for Sootblower Flow

The present invention relates to a method and a system for optimizing steam or other cleaning medium used during soot removal in a boiler in which energy is generated by fuel combustion, with accompanying production of soot, and heat energy is transferred from the product gases to a heated medium via heat exchanger tubes on which the soot collects, by; monitoring the mass flow rate of the

Mechanisms of Steam Soot Blower Erosion | Boiler Journal

May 10, 2012 · There are many mechanisms that can cause steam soot blower erosion of boiler tubes at various heat transfer sections. Knowing the way these mechanisms contribute to erosion will help to prevent loss of availability of boiler. Soot blowers are provided in boilers at various locations like water-walls, superheaters, reheaters, economizers and air pre-heaters.

Possible mechanisms. All blowers are set to be set at the right steam pressure recommended by the designer if this is not done then it leads to poor cleaning or higher rate of tube erosion due to high steam pressure. This is true for all soot blowers in the boiler starting from furnace to air pre-heater. The alignment of the blower with respect

Sootblower – T Energy

Soot deposited on the heating surfaces of a boiler acts as a heat insulator. The result is that less heat is transferred to the water to raise steam and more heat is wasted up the chimney. This leads to higher fuel consumption and/or poor steaming. A soot fire can be damaging to a boiler because it can cause localized hotspots to occur in the tubes.
