WebJun 22, 2013 · We want to remove sludge and debris of steam pipe lines by steam blowing method. If we want to have a efficient steam out as it said before, disturbance factor must be higher than 1.2. Normal operation condition of pipe line is: Pressure :22 bar Flow rate: 175 ton/hr Temperature: 245 oC WebDuring steam blowing, the Piping network should be blown with enough velocity of steam to ensure sufficient cleaning force for the removal of debris, rust, and scale. Typically during …

How to Clean Natural Gas Piping with Gas Blows - ResearchGate

WebNov 24, 2008 · The basis for steam blows is that the piping is blown, bypassing the turbine, with sufficient boiler pressure to ensure that the piping will experience a dynamic pressure to assure adequate cleaning. Typically, the boiler pressures during steam blow provide a dynamic pressure throughout the piping, which is at least 20% higher than would be ... WebTo make sure that this is the case the forces on the debris during steam blowing must be higher than those experienced in normal operations. The ratio of these forces is called the … right at home grayslake

Advances in Power Plant Steam Blow Cleaning Analyses

WebSep 9, 2014 · PRINCIPLE OF STEAM BLOWING To ensure that sufficient cleaning forces are applied to the piping, the steam momentum during the steam blow must be equal to or greater than the steam momentum at normal maximum load condition. The Cleaning Force Ratio (CFR) is typically used to evaluate if satisfactory blow conditions are obtained. 3. WebTo ensure cleanliness RIG will calculate cleaning force ratios for all engineered air blows along with associated air pressures and cleaning velocities. Similar to targeting during a steam blow an air blow can also have a target inserted … Web2.1 Cleaning Force Ratio (CFR) / Disturbance Factor (K) The Cleaning force ratio, R ≥ 1.5 is achieved, further defined by following. CFR = 90 Where, = Design mass flowrate during … right at home green bay wi
