Commissioning

Acid cleaning corrosion is a key factor to considering during the chemical cleaning activities. A few months after the completion of a combined cycle, the plant was forced to shut down due to operational instabilities and loss of pressure in the steam generator. An exhaustive inspection was conducted to find out multiple leaks in the

Consulting About Steam Blowing A few days ago, we were consulted about a very interesting case that I would like to share my opinion as it would be useful for engineers involved with commissioning: Can carryovers and/or water droplets affect the target plate during steam blowing? Yes indeed. Carryovers can affect final results, specifically magnetite

Kraft Recovery Boilers The Kraft process is a conversion reaction in which wood chips are digested in a batch reactor, at high alkaline water solution of NaOH and Na2S, to break up the lignin that holds the wood fibers together while obtaining almost pure cellulose, the main component of paper. The waste stream produced from

Fludization Aspects The fluidization potential (drag force) can be enhanced by minimizing the boundary layer thickness of the fluid, all along the surface

Having a complete understanding of the subject is a key factor for the performance of an effective chemical cleaning and the chemical treatment program to

It is of significant importance to collect samples from different part of the system during the treatment operation as color changes provide reliable information about the evolution of the

This journey shall help you to become aware of the importance of having a deep understanding
