Monitoring Coal-Fired Boilers
The continued rise of worldwide electricity consumption has put an ever increasing demand on power generation facilities. With coal-fired power plants, this demand results in challenges to increase production efficiency while minimizing environmental impact.
The challenge every coal plant owner or operator faces is to generate the maximum amount of energy with the lowest emissions in the safest and most economical way. Scale or slag buildup on platens and tubes results in inefficient heat transfer and can also damage the tubes.
Currently, coal plant operators use a number of ways to clean boiler tubes, but have inadequate methods to measure their effectiveness. Many of these methods have negative impacts such as prolonged downtime and thermal stress to the boiler tubes.
BoilerSpection is a revolutionary thermal imaging system with the ability to see through flames that helps coal plants run more efficiently, extract more energy from their coal, and increase productivity.
With BoilerSpection, coal plant operators can proactively manage their boilers by gaining visibility on scale buildup directly on the boiler tubes. The number of cleaning cycles and downpower operations can be minimized resulting in increased operating efficiency and reduced mechanical stress that can lead to tube failure. Return on investment (ROI) studies by customers have found ROIs measured in only a few months, not years.
The BoilerSpection SD imaging system is provided with a water-cooled, wide angle boroscope lens, and full retraction system that attaches to the furnace wall via a mounting plate. The system can be installed and commissioned either while the boiler is operating, or during a planned outage.
The BoilerSpection MB system is an easy-to-use mobile imaging solution that can be used for boilers and furnaces. This portable unit includes all the components necessary to record images in only minutes. Armed with this information, operators can then direct cleaning operations, regulate flow of fuel and air, reduce emissions, reduce fuel consumption, and speed boiler start up processes.
Typical installations have anywhere between three and twelve cameras, and one to two Furnace Exit Gas Temperature sensors per boiler. LumaSpection is configurable to meet different requirements.
Worldwide installation of over 80 units in furnace systems.
Return on Investment of less than one year in most cases.
Ease of installation allows system to be integrated during operation of boiler.
- Capture lost boiler capacity by reducing unnecessary cleaning and pinpoint issues before they grow into problems
- Increase efficiency by improving heat transfer with precise knowledge of slag and fouling conditions
- Manage combustion by tracking uniformity of ash deposits
- Optimize fuel-switching by directly and accurately measuring ash rate and uniformity as fuel changes
- Lower maintenance costs by optimizing cleaning and identifying large deposits before they cause damage to boiler tubes
