Page iii - COMBUSTION OF COAL AND THE PREVENTION OF SMOKE," BY CW WILLIAMS, AICE, AND "THE ECONOMY OF FUEL," BY T. SYMES PRIDEAUX. WITH EXTENSIVE ADDITIONS ON RECENT PRACTICE IN THE COMBUSTION AND ECONOMY OF FUEL: COAL, COKE, WOOD, PEAT, PETROLEUM, ETC.
Page 24 - for want of oxygen. It is in consequence of this structure of the flame that we so materially increase its heat, by propelling a current of air through it by the blow-pipe." Dr. Eeid observes, " The flame of a candle is produced by the gas formed around the wick acting upon the oxygen of the air
Page 330 - The economy in the fuel is esteemed practically as onehalf, even when the same kind of coal is used, either directly for the furnace or for the gas-producer ; but, as in the latter case the most worthless kind can be employed, such as slack, &c., which can be converted into a clean gaseous fuel at a
Page 11 - hydrogen gases, the proportion of the latter in coal gas being estimated at about ten per cent. For the sake of simplifying the explanation, I will confine myself to the first. On analyzing this gas, we find it to consist of two volumes of hydrogen and one of carbon vapour ; the gross bulk of
Page 17 - we have seen, is a compound of one atom of carbon with two atoms of oxygen ; while carbonic oxide is composed of the same quantity of carbon with but half the above quantity of oxygen, as in the annexed figures. Carbon,
Page 11 - ascertaining of the quantity of oxygen with which it will chemically combine, and the quantity of air required for supplying such quantity of oxygen. Much of the apparent complexity which exists on this head arises from the disproportion between the relative volumes, or bulk, of the constituent atoms of
Page 34 - admis-sion of air (when properly regulated) at 35 per cent., and when passed through a fixed aperture of 43 square inches, at 34 per cent. This is a near approximation to the mean of five experiments, which, according to the preceding table, gives 33J per cent., which probably approaches as near
Page 6 - smoke. This is the fact, and it remains to be shown why the same language may not be applied to the combustion of the same coal and the same gas, in the furnace, as in the lamp. The classification of the various kinds of coal, the details of an elaborate analysis, made by Mr. Thomas Richardson,
Page 101 - specific gravity, that being then the sole motive power. After ebullition, however, a new state of things is created. The columns of rising steam obtain great physical power, violently and mechani-cally forcing upwards the water which comes in their way. Vertical streams are thus induced, putting in motion a body of water far greater than would
Page 32 - very satisfactory and important results deduced therefrom. " In giving an account of Mr. Houldsworth's experiments, it will be necessary to describe the instrument by which they were made, and also to show the methods adopted for indicating the temperature, and the changes which take place in the surrounding flues.
