FTIR spectroscopy measurements and CFD simulations of the pollutants arising from unflued combustion in a room.

Simulates a kitchen for a study of indoor air quality. An extractive FTIR technique was used to measure combustion products from unflued combustion from a gas cooker in a ventilated room. On a comparison of the results with those from conventional instruments, the FTIR technique showed good agreement. The study incorporated the obscuring of the spectrum due to the effects of H2O and carbon dioxide and detection limits. The conditions in the room were investigated using CFD. Worthy of note was the complicated flow situation as the plume from the cooker interacted with the extraction hood.
