要約

The major advantage of atmospheric burners, which are applied both in households and in industry, is their noncomplexity, i.e., primary combustion air is entrained, so there is no need for a fan. Consequently, the main designing task is to provide optimal amounts of primary and secondary air to the burner, which will lead to a stable and efficient burner operation.
This research was focused on investigating the influence of access of secondary air on the operation of a novel, fully premixed atmospheric burner, which has an advantage of low NOx emissions (due to lean fuel conditions), but is prone to flame instabilities. This investigation helps predict the performance of the fully premixed atmospheric burner within the chamber, initially designed for a partially premixed atmospheric burner. For this purpose, an experimental setup with controllable accesses of primary and secondary air was built.
Experimental investigation showed that for a constant primary excess air ratio the availability of the secondary air significantly increased the emission of CO. Thus, besides reducing the heat efficiency of the combustion unit, the availability of the secondary air reduced the overall performance of the burner. The availability of the secondary air showed to be important for the burner operation in the current setup, i.e., when secondary air was not available, the chimney draft induced strong changes in the entrainment of primary air, which led to conditions under which the burner was not operable.
