Wall Blower F149
Operating Principle
- The lance tube with two opposite nozzles is helically moved into the boiler
- The blowing process begins as soon as the nozzle head has passed through the tube wall
- During the blowing process, the lance tube continues to move helically into the boiler
- During this process, the tube wall is cleaned in circular form
- Special control through an additional solenoid valve also enables cleaning of specific segments
- On reaching the prescribed travel, the direction of movement changes and the lance tube returns to its rest position
Technical Summary
The F149 wall blower is a sootblower suitable for cleaning of membrane wall heating surfaces in the furnace area and flue-gas recirculation ducts, which see heavy slagging and high flue-gas temperatures. The blower travels helically into the boiler to the prescribed travel, cleaning with water as a blowing medium.
- Cleaning Medium: Water
- General Application Areas: Furnace, flue-gas recirculation ducts
- Travel Range: 1.185 m
- Cleaning Arc: 30 ° – 360 °
- Key Industries: Power Generation, Other Industrial Processes
Key Features
- Stainless-steel water supply assembly with a solenoid operated valve
- Stainless-steel feed tube
- Stainless-steel drive spindle and lance tube with high performing nozzles
- Compact and stable casing constructed from standard sections
- Gear motor with an integral mechanism to initiate a variable speed drive to optimally and uniformly clean the furnace wall
- In-built air sealed wall-box with sealing elements corresponding to boiler pressure mode
Product Benefits
- Increased plant availability due to reliable cleaning, resulting in efficient plant operation
- Reduced Furnace Exit Gas Temperature (FEGT) and increased boiler efficiency through improved heat transfer
- Prevents heavy slagging
- Shorter boiler outage period
- Reliable and simple to maintain
- Intelligent, flexible operation, in conjunction with SMART Furnace (optional)
