Combustion, complete

The high explosive instability is due in part to the covalent character of the alkyl perchlorates, and also to the excess of oxygen in the molecule over that required to combust completely the other elements present (i.e. a positive oxygen balance).

The term absolute combustion is not the same as complete combustion. Complete combustion is a theoretical term, implying a theoretical goal that we might aim toward but will never quite reach on any real process heater, furnace, or boiler, whereas the point of absolute combustion represents the best achievable efficiency point of any such piece of equipment on any day of the week, at any hour or minute. 

As the breech mechanisms of present guns are not designed to achieve complete sealing off the gases of combustion(complete obturation), the base of combustible cartridges should be made of a non-combustible material. This material can be either metal(brass or steel) or a noncombustible plastic. Obturators prepd from polyethylene are described in Ref 13-Cartridges prepd by these methods are known as partially combustible(Rei 15)... 

Heating Value—The heat released when a fuel is combusted completely, corrected to standard pressure and temperature. The higher heating value is complete combustion with the water vapor in the exhaust gases condensed. The lower heating value is when the water vapor in the exhaust is in the vapor phase [2.4]. 

Because most of the ash is removed as molten slag, addition of a bottom grate is not necessary.7 However, small TDF is required, because much of the combustion must occur in suspension.7 TDF that is too large to combust completely can get carried over into the boiler or dust collection system, and cause blockage problems.9 Therefore, particle size may inversely determine the amount of TDF that can be used in a cyclone boiler.11 Three cyclone-fired boilers at utilities have burned 1M x 1" TDF in test operation, one at the 2 percent, one at the 5 percent, and one at up to a 10 percent level.3,9,12 One pulp and paper mill plans the use of TDF in a cyclone-fired hog-fuel boiler.13...

Sulfur burning furnaces are 2 cm thick cylindrical steel shells lined internally with 30 to 40 cm of insulating refractory, Fig. 3.3. Air and atomized molten sulfur enter at one end. Hot S02, 02, N2 gas departs the other into a boiler and steam superheater (Fig. 3.4). Some furnaces are provided with internal baffles. The baffles create a tortuous path for the sulfur and air, promoting complete sulfur combustion. Complete sulfur combustion is essential to prevent elemental sulfur condensation in downstream equipment. 

By coupling the Chromarod separation technique described in Section 11.4 with the reliable and robust NDIR (nondispersive infrared) technique for detecting the CO2 formed in the combustion, completely new ways of analyzing hydrocarbons are opened up. This principle of detection has the advantage that it is specific for CO2, i.e. cross-sensitivities are largely avoided.

Catalytic combustion. In the course of catalytic combustion, complete and rapid combustion is achieved at essentially lower temperatures as compared to thermal combustion. High efficiencies (92-99%) are achieved at 400°C. Various types of catalysts are used during the combustion, either...
