The engine was modified so that all compressor discharge could be removed and fed to an external burner, from which products of combustion were returned to drive the turbine.
32.
These burners are used where indirect heating is required, e . g . where the products of combustion are not allowed to combine with the atmosphere of the furnace.
33.
Much carbon monoxide gas was produced as a by-product of combustion, and carbon monoxide poisoning is a well recognized danger when machines are used, or fires occur in enclosed environments.
34.
The products of combustion left the chamber and passed through a narrow ceramic neck which reached temperatures of 2000 degrees F where the gases and tars released by the wood completed their burning.
35.
When the flame is no longer needed, the fuel valves are shut and the combustion air fan is left running to clear the combustion chamber of all unburnt fuel and products of combustion.
36.
Alaska House Bill 351 requires a carbon monoxide detector be installed in dwelling units that contain or are serviced by a carbon based fuel appliance or other device that produces by products of combustion.
37.
"' 2-Nitrofluorene "'is a by-product of combustion and is a nitrated polycyclic aromatic hydrocarbon ( fluorene ) . 2-Nitrofluorene is listed as an IARC Group 2B carcinogen, indicating it is possibly carcinogenic to humans.
38.
The code required a detector sensitive to any of the products of combustion to be placed in hallways outside bedrooms, with alarms audible in any bedroom in the house even when the doors are closed.
39.
The draught induced by the steam is used to draw the heat and waste products of combustion through the boiler and up the funnel, and so draw more air into the furnace, a force draught system.
40.
A "'muffle furnace "'( sometimes "'retort furnace "'in historical usage ) is a furnace in which the subject material is isolated from the fuel and all of the products of combustion, including gases and flying ash.
