2010. Kiev, Ukraine
The laboratory test verification of XPlate® Technology was carried in 2010 by The Coal Energy Technology Institute of the National Academic of Science (NAS), The Government of Ukraine. Tests of coal combustion, anthracite and bituminous coal combustion were implemented in circulating fluidized bed (CFB). The following was found during trial:
- It was observed the positive effect of the XPlate® units installation at primary and secondary air pipelines and at pneumatic coal feed system.
- The effect essence was the increase in temperature in the bed and in the top part of the furnace and the decrease of oxygen content in flue gases at constant fuel and air consumption.
- Fuel conversion (burn-out) degree in balance tests with XPlate® units installed was 0.4 – 2.5% higher than without the plates, with a simultaneous decrease in coal underburning.
- When bituminous coal burning with Xplate® units installed, the initial furnace temperature was achieved while fuel and air consumption reduced by 6%.
- Analysis of the results has high-reliably shown that possible side factors likely do not play a determining role in the observed positive effect.
- The results obtained allow recommending large-scale of XPlate® technology at thermal power plant and CHP boilers of various capacities.
2009. Didcot, UK
We have a laboratory engineering report tested earlier at the Combustion Test Facility of RWE Power International in Didcot, UK in 2009. The results indicated that XPlate® Technology did go some way to enhance the combustion. Heat flux measurements indicated that radiant heat transfer in the boiler may be increased whilst carbon in ash data indicated more complete coal combustion. Both of these effects may lead to a reduction in fuel consumption; trials on a power station would be required to confirm this.
