Self-cleaning of Ovens

The control of the self-cleaning procedure (pyrolysis) of especially equipped kitchen ovens is another focus of development. The underlying idea is to burn the organic residues at elevated temperatures (around 400 °C) and to detect the emerging volatile compounds. In order to minimize energy consumption, the process time should be kept as short as possible. During this process considerable amounts of CO and C02 are released. A decrease in concentration of these compounds can thus be taken is an indicator of the end of process. The most direct method would be the detection of C02 in the flue gas. The most common C02-

In this sub-chapter we intend to give an overview of household appliances using the different gas sensor principles mentioned in the previous chapters. The appliances can be divided into two categories gas sensors for safety and for comfort. Natural gas and CO-alarm systems for example are safety-relevant whereas air quality measurement, control of self-cleaning of ovens etc. are more or less a matter of comfort or energy-saving.
