Arun Shanbhag has a post full of photographs from blood pools, to chalk marks and a burning Taj Hotel.

During combustion of biogas containing siloxanes, silicon is released and can combine with free oxygen or other elements in the combustion gas.

A combination of biomass, aquifers, burning vegetable oil a process that, quite interestingly, was developed in Eastern Germany, at the time of its dependence on the Soviet Bloc.

You're just smelling for smoke so you can follow the trail back to a burning house, so you can find the boy who lost everything in the fire to see if you can save him.

210 people left the building on their own. 120 were evacuated during the fire (with active assistance from those gathered outside on the square!).

There is no secondary pollution (unlike the case of incineration where additional CO2 and NOx are produced from burning fuels) and degradation products form additional biomass, carbon dioxide and water.

Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two thirds) derived from the combustion air, carbon dioxide (), and water vapor as well as excess oxygen (also derived from the combustion air).
