US4359800A - Sootblower feed and lance tube …

The feed tube of a long retracting sootblower has a lance tube slidably overfitted thereon which is of an inside diameter somewhat exceeding the outside diameter of the feed tube, to provide a relatively narrow gap therebetween. The open end of the feed tube has a turbulizer mounted therein contoured to impart a helical component to the blowing fluid which blows into the lance tube from the

(PDF) Sootblower Lance Tube Corrosion in Recovery …

Severe internal corrosion of soot blower lances in two recovery boilers was likely a result of flue gas infiltration into the lance tubes, which formed an acidic condensate that rapidly attacked

Tube Failures in High Pressure Boilers

However, a few like water side corrosion, caustic corrosion, hydrogen damage in the water wall, soot blower erosion, damage during maintenance cleaning, and tube internal pitting can be totally eliminated in a boiler if good operating and maintenance practices as told by the boiler designers are followed.

Soot Blowers - an overview ScienceDirect Topics

The sensing elements are located in every region of the tube walls surrounding the soot blowers to detect the rate of local heat transfer from the hot flue gas to the steam/water tubes in the furnace or in the air heater heat-exchanging elements (flue gas side). The heat flux meter output is utilized for operating the soot blower.

Boiler soot blower installation instructions - SOOT …

In some cases, the soot blower is entirely supported by steel frame. For soot blower using compressed air as blowing medium, boiler soot blower is horizontal when the boiler is running. While for soot blower using steam, the soot blower shall have an inclination so that condensate can drain off from the lance tube tip hole. Installation drawing

2004-7-27 · lance tube at elevated temperatures while it is in the boiler. The nozzle section at the end of the lance is made of stainless steel (typically SS310) since it subjected to the hot flue gas longer than any other component of the soot blower. Over the years, lance tube corrosion was found to occur mostly in the part closest to the boiler.

Efficient Cleaning of Heating and

2018-2-2 · Incorrect sizing of the internal steam feed tube can have expensive consequences. If the feed tube outlet is positioned too far from the boiler wall opening, the steam can condense in the feed tube whilst the sootblower is not in operation. Consequence: Condensate continually drips on the inner lance tube wall, eventually leading to corrosion.
