Ash Fouling Monitoring and Key Variables Analysis for Coal Fired Power Plant Boiler

Ash deposition on heat transfer surfaces is still a significant problem in coal-fired power plant utility boilers. The effective ways to deal with this problem are accurate on-line monitoring of ash fouling and soot-blowing. In this paper, an online ash fouling monitoring model based on dynamic mass and energy balance method is developed and key variables analysis technique is introduced to stu...

Statistical modeling of an integrated boiler for coal fired thermal power plant

The coal fired thermal power plants plays major role in the power production in the world as they are available in abundance. Many of the existing power plants are based on the subcritical technology which can produce power with the efficiency of around 33%. But the newer plants are built on either supercritical or ultra-supercritical technology whose efficiency can be up to 50%. Main objective...

Advanced Emissions Control Technologies for Coal-Fired Power Plants

Mercury Control Alternatives for Coal-fired Power Plants

Coal-fired power plants in the United States may have to reduce their mercury emissions by up to 90% by 2007 2009 due to proposed regulations that could affect up to 1,100 utility boilers. Air pollution control system components such as electrostatic precipitators, baghouses, NOx reduction catalysts, SO2 scrubbers, and their various configurations in utility applications significantly impact me...

Mining Temporal Data: A Coal-Fired Boiler Case Study

This paper presents an approach to control pluggage of a coal-fired boiler. The proposed approach involves statistics, data partitioning, parameter reduction, and data mining. The proposed approach was tested on a 750 MW commercial coal-fired boiler affected with a fouling problem that leads to boiler pluggage that causes unscheduled shutdowns. The rare-event detection approach presented in the...
