Steam /Air Blowing
Steam /Air Blowing
A process for the removal of oxide scales and construction debris by mechanical drag forces. SOLARCA employs the following methods:
- Conventional steam blowing
- Silent steam blowing
- Air Blowing
- References
- Case Studies
Silent Steam Blowing
- Continuous
- Low noise level < 80 db
- Reduced blowing time
- Achieved at low pressure
- Steam flow requirement approx. 30% of maximum capacity
- Has technical advantages and economic benefits
Conventional Steam Blowing
- Discontinuous
- High noise level > 120 db
- High number of blowing cycles
- Longer Blowing time: 2-4 weeks per system cleaned
- Steam lines subjected to high mechanical forces and thermal stress
- Special supports in the provisional blowing lines to avoid reaction force problems
Air Blowing
- Discontinuous
- Air blowing cycles at high pressure
- Instantaneously creates high flow rates using a quick opening valve
- High drag forces giving very effective fluidisation of debris
- Considerable reduction of cleaning programme time and subsequent commissioning
