During the combustion process when using coal, about 20% of combustion residue is left over.

The combustion residue, smelt exits through smelt spouts-9 to the dissolving tank-10.

Converting combustion residue to marketable byproducts.

In 1974, at the location of the field Çerkezi, not far from Ulpiana, a large mound was discovered that combustion residue contained a princess.

Fouling of the mechanism by black powder combustion residues and thus difficulties in closing the breech were reported as a problem after prolonged firings.

The containers typically included mixed- and laboratory waste, rubble, scrap, filter residues and combustion residues.

His nitrocellulose-based Poudre B (Powder B) was three times more powerful than black powder for the same weight and left very little combustion residues after firing.

While the Agency continues to support safe and protective beneficial reuse of coal combustion residues, the C2P2 program webpages have been removed while the program is being re-evaluated.

This is in part due to enhanced recovery of ceramic materials reused in construction, as well as ferrous and in some cases non-ferrous metals that can be recovered from combustion residue.

The heating season is over, acids formed by combustion residues have not yet had a chance to corrode chimney parts seriously and plenty of time is available for repairs before cold weather sets in again.

The National Academy of Sciences noted in 2007 that "the presence of high contaminant levels in many CCR (coal combustion residue) leachates may create human health and ecological concerns".

Without bore evacuators, hot gases and other combustion residue leaks into the tank's interior, depleting oxygen levels and filling it with a foul odour that can easily induce nausea and distract the crewmen from their tasks.
