Burning fossil fuels in the earth’s atmosphere produces nitrogen oxides. To protect both humans and the natural environment, these emissions must remain below the legal limits at all times.

With SIGLAS^® Lambda, we’ve solved this problem for glass manufacturers by introducing targeted control of excess air during combustion. Zircondioxide oxygen sensors measure the proportion of oxygen in the exhaust air. The system control uses these measurements to calculate the current excess air and regulates the amount of air required for optimum emission. No secondary NO_x reduction measures are required.

In addition, optimization of heat exchangers and combustion regulation enable you to run temperatures that are 30 to 40 K lower in the upper oven. You can save up to 5% in power costs as a result.
