Our Technology

 

Our state-of-the-art technology offers customers valuable insights into the combustion process. However, to achieve the best results, it should be viewed as a complementary support tool. Effective optimization depends on the quality of data collected in the field – the more comprehensive the information, the more successful the overall optimization will be.

 

Since 2006, the e.con team has consistently demonstrated our ability to support your strategies with our technology. To cope with the dilemma of greenhouse gas emissions on the one hand and power demand on the other, coal fired power plants become of enormous importance. 

 

Therefore e.con and partners have developed comprehensive solutions for power plants to contribute their technology toward a better environment. The objectives for a more environmentally friendly operation of coal fired power plants while still supplying

existing power demands are:

​​

      High availability

      High efficiency

      High flexibility

      Low emissions

Measurement and Installation

​​

To determine the optimal positions for both the measurement and installation of the location for PGB-1 valves, various visual representations were used. On the right, the isometric layout of the

burner line is shown, while the left-hand illustration displays the position

of the already installed valves. These visualizations are crucial to ensure precise placement of the valves and sensors and thereby guarantee

reliable measurement results.

Measuring

​

The coal conduit layouts of power plants vary significantly. Developing similar coal pipe resistances to achieve an even two-phase coal flow was one of the challenges power plant designers aimed to overcome. Due to these structural challenges, unique measuring technologies must be used to provide the most reliable and accurate information.

Installed sensors

​

The latest electromagnetic

wave technology is used and housed inside a sealed stainless steel casing.

 

The sensing technology generates a homogeneous field within the coal pipe for measurement. The reflection of the moving particles is analyzed based on their frequency and amplitude.

The coal flow balancing valves balanced the coal flow within 5.12 %. Consequential effects were a reduction in CO on average from 951 ppm to 294 ppm. The 02 spread in the measurements was also significantly reduced from and average of 0.89 % to 0.19 %.

CO reduction has benefits in the area of: ï»¿ï»¿reduced furnace wall boiler tube wastage, improved boiler availability, ï»¿ï»¿improved heat rate if total combustion air is held constant or controlled more tightly than currently.

PA and SA testing showed potential benefits: NOx reduction & Heat rate improvement
