✦ Synopsis

The operation of mechanical exhaust in a small retail shop fire will be studied with a two-layer model. Different equations on axisymmetric fire plume entrainment and spill plume will be considered. A zone model has been developed to predict the fire growth in retail shops. Correlation between the mechanical exhaust rate and plume entrainment rate for keeping the smoke layer interface at a certain height under a steady burning fire will be analyzed.

A series of full-scale burning tests were carried out in a chamber with a vertical vent. In addition to validating the developed model, the results will also be compared with those predicted by another zone model CFAST. The effectiveness of mechanical exhaust in retail shop fires will be discussed. How different plume correlations can be applied will be investigated and compared. Some factors affecting the calculation will also be analyzed.

Replacing fossil fuels by renewable sources of energy is one approach to address the problem of global warming due to anthropogenic emissions of greenhouse gases. Wood combustion can help to replace fuel oil or gas. It is advisable, however, to use modern technology for combustion and exhaust gas af
