Boiler 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...
متن کاملEffect of Corrosion on Heat Transfer through Boiler Tube and Estimating Overheating
The product of corrosion in the feed water system transported into the boiler and gets deposited on the internal surface of waterwall tubes. Proper treatment of boiler feedwater effectively protects against corrosion of feedwater heaters, economizers, and deaerators. It leads to overheating and on-load corrosion and ultimately tube failure.. Heat is transferred through a thin layer of superheat...
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 کاملEMAT Integrated with Vertical Climbing Robot for Boiler Tube Inspection
National Thermal Power Corporation (NTPC) has signed an MoU with Bhabha Atomic Research Centre (BARC) for design and development of automated boiler tube inspection system for vertical water wall tubes. A vertical climbing robot has been developed for this purpose at Division of Remote Handling & Robotics (DRHR), BARC. Recently, an Electromagnetic Acoustic Transducer (EMAT) has been integrated ...
متن کاملThe Influence of Gas Heating on Material Properties of P92 Steel During Boiler Tube Alignment
Preliminary note The pipes and the pipe walls are of the utmost importance to all power plant facilities. Under exploitation, they are subjected to effects of aggressive media, high temperature corrosion and possible mechanical damage. Consequently, special attention is paid to the control of material properties during the power plant construction in order to minimize the risk of flaws or failu...
