ANFIS Controller for Water Level Control of a Boiler Drum

The water level in boiler drum is the critical control parameter to be addressed for providing the efficient and safe operation of steam generators in power plants. The regulation is achieved by using the Artificial Intelligence (AI) technique, namely, Adaptive Neuro-Fuzzy Inference System (ANFIS). It has the capability of self-learning as ANN with the linguistic expression function of fuzzy in...

Efficient model-based leak detection in boiler steam-water systems

A model-based least-squares algorithm with a time-varying forgetting factor is developed for leak detection in boiler steam-water systems. The algorithm has been tested using real industrial data from Syncrude Canada, and has proven to be effective in detection of boiler tube or steam leaks; proper implementation of the algorithm would lead to early leak warning, which is important in maintaini...

Water Purification in Thailand

Water is a necessary part of life, but without proper filtration, it could cause problems such as illness or death. While citizens of developed countries may take the water that flows from their taps for granted, many parts of the world do not have access to clean water. A small village in Thailand called Nong Bua is one such community that is hindered by the quality of their water supply. Nong...
