When black powder burns, the first portion to receive the fire undergoes a chemical reaction which results in the production of hot gas. The gas, tending to expand in all directions from the place where it is produced, warms the next portion of black powder to the kindling temperature. This then takes fire and burns with the production of more hot gas which raises the temperature of the next adjacent material. If the black powder is confined, the pressure rises, and the heat, since it cannot escape, is communicated more rapidly through the mass. Further, the gas- and heat-producing chemical reaction, like any other chemical reaction, doubles its rate for every 10° (approximate) rise of temperature. In a confined space the combustion becomes extremely rapid, but it is still believed to be combustion in the sense that it is a phenomenon dependent upon the transmission of heat. [Pg.10]

Ordinarily, a combustible substance does not burn spontaneously. A combustible substance must reach the ignition or kindling temperature to start burning. External heat has to be supplied to start combustion. The temperature at which a combustible substance starts to bum is called its kindling or ignition temperature. [Pg.67]

Although aluminum is a very active metal, it enters into many reactions with extreme difficulty on account of a thin, tenacious coating of oxide, which keeps it physically separated from the reacting material. Aluminum powder alone cannot be made to bum in air, but when it is mixed with lampblack and any part is brought to the kindling temperature, which is very high, the combustion spreads throughout the mass. The function of the carbon is to react with this oxide layer. Carbon alone reacts with aluminum oxide to yield the carbide... [Pg.153]

Spontaneous Combustioil. Reactions such as the combustion of fuels proceed very rapidly when combustion is begun, but fuels may remain indefinitely ih contact With air without burning. In these cases the rate of reaction at room temperature is extremely small. The process of lighting a fire consists in increasing the temperature of part of the fuel until the reaction proceeds rapidly the exothermic reaction then liberates enough heat to raise another poriion of the fuel to (he kindling temperature, and in this way the process is continued. [Pg.410]

Define the following expressions empirical method, metastable equilibrium, kindling temperature, thermostat, interface, dynamic steady state, unimolecular reaction, bimolecular reaction, homogeneous reaction, heterogeneous reaction. [Pg.412]

Chemistry of friction matches The striking surface on a box of friction matches is powdered glass and glue. The P4S3 tip has a low kindling temperature. When the tip is rubbed on the striking surface, the heat from the friction causes it to ignite. [Pg.275]

The ignition or kindling temperature is an important factor in some catalytic applications. [Pg.353]

Heating baths should be in durable, nonbreakable containers and set up on a firm support so that they will not be likely to tip over. They should not be placed near flammable and combustible material, including wood and paper which, if exposed to continuing heat over a sufficient period of time, could reach kindling temperatures, or near sources of water (particularly deluge showers) which could cause the bath liquid to splatter violently from the container. In most cases, the bath temperatures are hi enough to cause severe bums. If it is necessary to move the full container, it should be done while the liquid is cool, again to avoid the risk of bums. [Pg.200]

Performance guarantee should be obtained for improving production rate, product quality, expected pressure drop (through fixed catalyst beds), permissible mini-mum/maximum operating temperatures, maximum feed rates or concentration of reactants, attrition, kindling temperature, equilibrium conversion, etc. [Pg.61]
