Abstract

The paper presents the results of numerical simulation of two operation modes of mono- and bi-directional combustors. Pulverized peat is used as fuel. The calculations performed in a stationary RANS device have shown that bidirectional combustor type has greater operation flexibility in terms of environmental and energy indicators. It also has a wider range of stable operation and its flow and flame structures make it possible to achieve the values of carbon monoxide emission CO 286 mg/nm3, nitrogen oxides NOx 4 mg/nm3 and combustion efficiency η=0.999. The mentioned indicators of the bidirectional combustor are achieved at the operation mode characterized by the air-fuel equivalence ratio αΣ=2.41. The obtained results are caused by a valuable increase in the fuel residence time in toroidal zone of the bidirectional vortex chamber. This fact provides completing the most of chemical reactions at lower bulk combustion temperature.

Keywords:

swirling flow, unidirectional vortex combustor, bidirectional vortex combustor, fuel dust, peat
