Tube Temperature Distribution in Water Tube Boiler- A Parametric Study by Finite Element Method
This paper presents the application of finite element method (FEM) to analyze the tube temperature distribution in a water tube boiler. Two-dimensional (2-D) finite element models are developed where the axi-symmetric triangular elements for the cross section area along the water tube are applied in computer software namely MSC Patran-Nastran. The analysis of the temperature distribution for ev...
متن کاملMining 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...
متن کاملFurnace Wall Corrosion in a Wood-fired Boiler
The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals. These elements increase the corrosion problems at the furnace walls where...
متن کاملPrediction of Slag Occurrence in a Lignite-Fired Utility Boiler
Lignite from Mae Moh mine is the largest source of solid fuel for electricity generation in Thailand. It is used in pulverized coal-fired boilers of a 2400 MW thermal power plant. Its high CaO content in ash is a major concern that can affect severe slagging. In this paper, potential of slag occurrence in the power plant was investigated by numerical simulation. The FactSage thermochemical pack...
متن کاملBoiler tube corrosion characterization with a scanning thermal line
Wall thinning due to corrosion in utility boiler waterwall tubing is a significant operational concern for boiler operators. Historically, conventional ultrasonics has been used for inspection of these tubes. Unfortunately, ultrasonic inspection is very manpower intense and slow. Therefore, thickness measurements are typically taken over a relatively small percentage of the total boiler wall an...
