No, you're not smelling burning bodies and hair in Lake Worth

Jamel Laneé at NBC5/WPTV does a very fair and accurate news segment on the crematorium in Lake Worth having issues with their facility. Here is an excerpt from the text of her report:

     Some living near the All County Funeral Home and Crematory are concerned that dark smoke coming from the funeral home is possibly ashes of deceased people. [it's not]
     The Palm Beach County Health Department said that what people are actually seeing is soot, which it said is similar to what is seen when diesel is burning.
     The Health Department, which oversees crematories, showed up after it received several complaints along with pictures showing the thick, black smoke coming out of the building.
     Burners within the incinerators are reportedly not working correctly and the Health Department is trying to figure out why.

Here is the definition of soot: a black, carbonaceous substance produced during incomplete combustion of coal, wood, oil, etc., rising in fine particles and adhering to the sides of the chimney or pipe conveying the smoke: also conveyed in the atmosphere to other locations.

For example, when you see a truck going from a stop and gaining speed you'll see a puff of smoke from some vehicles. This is when the truck is switching gears and the result is 'incomplete combustion' of the diesel fuel.
