Noun:

अथ जलकर कोयला हो जाना,

carbonization's Usage Examples:

Unfortunately, tho, the process of carbonization which preserved them has also rendered them, till now, largely illegible.

The final solution of the question of enrichment of gas by hydrocarbons derived from tar may be arrived at by a process which prevents the formation of part of the tar during the carbonization of the coal, or by the process devised by C. B.

The higher the heat of carbonization the more naphthalene appears to be produced, and gas managers of to-day find the removal of naphthalene from the gas a difficult problem to solve.

The heating as well as the illuminating value of the gas per unit volume is lowered by over-baking, and Dr Bueb gives the following figures as to the heating value of gas obtained from the same coal but by different methods of carbonization: Vertical Retorts, 604 British thermal units per cub.

For the withdrawal of the residual coke at the end of the carbonization, the lower mouthpiece door is opened, the barrier removed and the coke in the lower part of the retort is "` tickled" or gently stirred with an iron rod to overcome a slight adhesion to the retort; the entire mass then readily discharges itself.

is probably heated to only 600° C. Moreover, the gases and vapours in the retort are subjected to a period of heating which varies widely with the distance from the mouth of the retort of the coal that is undergoing carbonization.

One of the most striking alterations of cell-walls is that termed carbonization, in which the substance gradually turns black, hard and brittle, as if charred - e.g.

A volatile product of offensive odour obtained in the carbonization of bones for the manufacture of animal charcoal.

The earliest attempts at enrichment by oil gas consisted in spraying oil upon the red hot mass in the retort during carbonization; Enrich- but experience soon showed that this was not an econo- meat by mical method of working, and that it was far better to oil gas.

Sugar charcoal is obtained by the carbonization of sugar.

carbonization's Meaning':

the destructive distillation of coal (as in coke ovens
