Abstract [en]

The mathematical background to the gas analysis problem is that the measurement system introduces a time constant into the gas analysis values. This time constant is not only a simple delay of the signal but also involve a damping of the amplitudes in the signal. Therefore, the registered values by measurement system can be treated as the convolution between the system response and the real gas analysis values. In this paper the plug flow with an overlaid axial diffusion was introduced to simulate the delay and damping effects of gas measurement system. The numerical method developed here is to extract the real gas values from the measured data in the de-convolution way to find what the reality is behind the registered values. All registered data were collected by two different gas analysis systems for measuring the gas out of a pellets burner – Velmax (Finnish brand). This numerical method is meaningful to get closer to the reality of measured data which is definitely needed step for the improvement of controlling the small scale combustion even though it still can be developed further.
