Incombustibility

The fuel value of most solid wastes is usually sufficient to enable self-supporting combustion, leaving only the incombustible residue and redlicing the volume of waste eventually consigned to sanitaiy landfills to only 10 to 15 percent of the original volume. The heat released by the combustion of waste can be recovered and utilized, although the cost of the recoveiy equipment or the distance to a suitable point of use for the heat may make its recoveiy economically infeasible. 

They may produce large volumes of incombustible gases which dilute the air supply.

Fibres phosphorylated in this way and containing 8—10% of diethylamino-dimethoxy-phosoryl groups are incombustible. 

Commonly also known as cinder or slag. Clinker is the mass of fused ash that results after the incombustible residual material from combustion cools down from a molten state. 

There are several authors who have shown interest in estimating mixture f iash-points from the point of view of studying mixtures of inflammable sut tances, and mixtures of an inflammable substance with one or several incombustible substances. This latter aspect was of particular interest because this type of mixture is sometimes used to improve solvent qualities and reduce the inflammability. 

These incombustible substances are halogenous derivatives whose extinction properties are well known and some molecules were used as extinction agents before it was realised they were toxic. Paint stripper containing methanoi and dichloromethane...

Calculation of Cg = AHc - AH, actually refers to the complete oxidation reaction of the molecules indeed, this applies to the reactions between incombustible substances. 

There have also been fires of dichloroethylene, which is well known for being incombustible. (It may be that the ignition was due to the formation of chloroacetylene). 

Water is non-flammable and incombustible A decisive advantage in terms of safety and occupational health... 

The chaotropic properties of many chemical compounds prevent the H2O cage structures necessary for the formation of solvates and thus facilitate the transfer of nonpolar molecules between nonaqueous and aqueous phases. Water is incombustible and nonflammable, odorless and colorless, and is universally available in any quality important prerequisites for the solvent of choice in catalytic processes. The DK and d can be important in particular reactions and are advantageously used for the analysis and control of substrates and products. The favorable thermal properties of water make it highly suitable for its simultaneous dual function as a mobile support and heat transfer fluid, a feature that is utilized in the RCH/RP process (see below). 

As increasing amounts of an incombustible gas or vapor are added to the atmosphere, the flammability limits of a gaseous fuel in the atmosphere approach one another and finally meet. Inert diluents such as C02, N2, or Ar merely replace part of the 02 in the mixture, but these inert gases do not have... 

The Greek asbestos means inextinguishable, but it is apparent from early descriptive comments that the characteristic of incombustibility was implicit (Luschen, 1968). Old synonyms for asbestos, such as salamander stone, referring to a mythical animal that endured fire without harm encompass both meanings, as does the belief that tomb lamps with asbestos wicks burned indefinitely, or at least until all of the oil, but not the wick, was consumed (Theophrastus, brans, by Caley and Richards, 1956). 

The material called asbestos was first identified as fibers that were sufficiently flexible for weaving and white to gray color. It was generally known to be incombustible and to remain unchanged up to temperatures of red heat, which was considered a useful property. But its insolubility in water or mild alkaline and acid solutions seems not to have been recognized or mentioned.

Philalethes says, in A Brief Guide to the Celestial Ruby. "The Philosopher s Stone is a certain heavenly, spiritual, penetrative, and fixed substance, which brings all metals to the perfection of gold or silver (according to the quality of the Medicine), and that by natural methods, which yet in their effects transcend Nature.. . Know then that it is called a stone, not because it is like a stone, but only because, by virtue of its fixed nature, it resists the action of fire as successfully as any stone. In species it is gold, more pure than the purest it is fixed and incombustible like a stone, but its appearance is that of very fine powder, impalpable to the touch, sweet to the taste, fragrant to the smell, in potency a most penetrative spirit, apparently dry and yet unctuous, and easily capable of tinging a plate of metal. If we say that its nature is spiritual, it would be no more than the truth if we described it as corporeal, the expression would be equally correct."... 

In addition to these advantages, the phlogistic theory was based on experiments, and led to experiments, the results of which proved that the capacity to undergo combustion might be conveyed to an incombustible substance, by causing it to react with some other substance, itself combustible, under definite conditions. The theory thus prepared the way for the representation of a chemical change as an interaction between definite kinds of substances, marked by precise alterations both of properties and composition.
