Almost any flammable mixture will, under favorable conditions of confinement, support an explosive flame propagation or even a detonation. When a fuel-oxidant mixture of a composition favorable for high-speed combustion is weakened by dilution with an oxidant, fuel, or an inert substance, it will first lose its capacity to detonate. Further dilution will then cause it to lose its capacity to burn explosively. Eventually, the lower or upper flammability limits will be reached and the mixture will not maintain its combustion temperature and will automatically extinguish itself. These principles apply to the combustible cryogens hydrogen and methane. The flammability and detonability... 

Storage of flammables and combustibles requires special attention. This discussion covers a few basic storage principles. However, applicable sections of the National Fire Code have greater details for particular storage matters focused on fire protection. 

Designs should prevent and manage combustible and explosive mixtures in air. Particularly important are processes and operations where flammable mixtures of gases, vapors, and dusts with air can occur. This principle includes reducing oxidizers that add to the explosive energy of a combustible material. Fuel and oxidizers require separated storage. That is because of the increased risk when fuels and oxidizers are located adjacent to or near each other.

An alternative to placing electronic products waste in dumps and landfills is to destroy the waste by incineration. One type of incinerator is the rotary kiln that uses the energy from liquid, combustible hazardous waste to increase the temperature of the kiln for drying cement. The chemical industry disposes of high energy-capacity, flammable liquids in this manner. Incinerators that bum hazardous chemical waste must be monitored and achieve a destruction removal efficiency (DRE) rate of at least 99.99 percent of the principle organic hazardous constituents of the waste. 

From a theoretical standpoint, one can have a situation where the AH < 0, but there is enough work done on the system that makes AH > 0. 149. A gas stove works by combustion of a flammable fuel. Once shut off, the heat source instantly disappears. An electric stove works by the principle of heat conduction. Even after the electricity is shut off to the heating coil, it fakes time for the coil to cool because of its heat capacity, and therefore it continues to supply heat to the pot. 150. The answer is (a). IM. The answer is (b).
