N2 - The concept of the periodic mixing and combustion process, which has been presented earlier [1, 2], has been implemented in a nearly adiabatic combustor for investigations at atmospheric pressure. The objective of this combustion process is to achieve stable combustion at adiabatic flame temperatures being considerably lower than the lean blowout temperature of aerodynamically stabilized flames with low pressure drop in the combustor in order to reduce NOx emissions and to achieve CO emissions near the thermodynamic equilibrium. For preheat temperatures between 390 K and 790 K, the periodic mixing combustor can be operated near the lean blowout limit with adiabatic llame temperatures down to 1510 K - 1600 K. The test combustor yields over the entire operation range of 1:4 (thermal powers from 47 kW up to 175 kW) very low emissions of NOx below 1 ppm(v) (15% O2, dry) and of CO below 8 ppm(v).
