Sensory combustion optimisation of gas combustion systems

Today, the quality of gas is already subjected to non-negligible fluctuations in the natural gas grid. New repositories, an altered distribution structure, and, especially, the supply of regenerative gases such as biogas and wind-hydrogen increasingly alter the concentrations of hydrocarbon, hydrogen, and inert gas components in the gas and thus its combustion properties. This has an effect on the combustion process and therefore on the efficiency and emissions of gas furnaces. A combustion control system to compensate for these gas quality variations and other disturbances on the process is therefore essential. In particular, the use of robust exhaust gas sensors for the measurement of oxygen (O2) and for the detection of unburned gas components such as CO, H2, and HC (COe) allow simple control strategies for the self-adaptive optimisation of combustion and increases the reliability and operational safety of the gas combustion system.
