Page 31 - ... down it is a solid plate, and for the rest of the distance consists of strong horizontal plate bars where air enters, the whole being at an inclination such as that which the side of a heap of coals would naturally take. Coals are poured, through openings above, upon this combination of wall and grate, and being fired at the under surface, they burn at the place where the air enters ; but as the layer of coal is from 2 to...
Page 31 - On the other hand, the entering gas and air always pass upwards through the regenerators, so that they attain a temperature equal to a white heat before they meet in the furnace, and there add to the carried heat, that due to their mutual chemical action. It is considered that when the furnace is in full order, the heat carried forward to be evolved by the...
Page 31 - ... hydro-carbons. The water, which is purposely introduced at the bottom of the arrangement, is first vaporized by the heat, and then decomposed by the ignited fuel, and re-arranged as hydrogen and carbonic oxide ; and only the ashes of the coal are removed as solid matter from the chamber at the bottom of the fire-bars. " These mixed gases form the gaseous fuel. The nitrogen, which entered with the air at the grate, is mingled with them, constituting about a third of the whole volume. The gas rises...
Page 50 - ... glowing. The standard rate of consumption for the candles shall be 120 grains each per hour. Before and after making each set of ten observations of the photometer the gas examiner shall weigh the candles, and if the combustion shall have been more or less per candle than 120 grains per hour, he shall make and record the calculations requisite to neutralise the effects of this difference. The average of each set of ten observations is to be taken as representing the illuminating power of that...
Page 31 - ... regenerators and air-ways, which were carrying off the expended fuel, can in a moment be used for conducting air and gas into the furnace ; and those which just before had served to carry air and gas into the furnace now take the burnt fuel away to the stack. It is to be observed, that the...
Page 31 - ... through which it passes before it enters the furnaces. A regenerator is a chamber packed with firebricks, separated so as to allow of the free passage of air or gas between them. There are four placed under a furnace. The gas ascends through...
Page 31 - Passing onwards to the other end of the furnace, they (that is, the combined gases) find precisely similar outlets, down which they pass, and traversing the two remaining regenerators from above downwards, heat them intensely, especially the upper part, and so travel on in their cooled state to the shaft or chimney.
Page 72 - ... and should be rolled when the sun has warmed it well. Those parts in angles should be well rammed and trimmed off with a light shovel. Though apparently a simple manufacture, there is a little difficulty in ascertaining the proportion of tar to gravel or cinder-dirt. A little experience will only be necessary in this, as well as in all other manufactures, to enable anyone to carry it out successfully. This pavement cannot be spoken of too highly, as it is cheap, wears well, and can be easily...

Page 72 - TURE be tolerably even. It is advisable to have the ground next the curb well trodden on and rammed before the pavement is laid, otherwise there will be an unseemly hollow next the curb. In laying, the rough stuff is put down first and rolled tolerably firm, then the second quality is put on, then the third, and when the whole has been raked level, a little of the finest material is sifted on through a sieve with J-in.
