Hydrocarbon Furnace

A furnace having special burners suitable for using liquid fuel. The burners consist of an apparatus which allows a forced jet of air and steam to carry with them a certain quantity of petroleum which is distributed into the furnace in the form of spray, and there burns with an intensity proportionate to the amount of fuel supplied. Hydrogen is the lightest substance known, and possesses nearly all the properties of a non-metal in such perfection, that chemists have long hesitated to class it with the metals, though its chemical relations clearly show it to belong to that class of elements. It combines with nearly every non-metal, but with only two or three of the metals. Hydrogen is colorless, tasteless, and inodorous when quite pure. It is inflammable, and burns with a pale yellowish flame, evolving much heat but very little light. The result of the combustion is water. It has never been liquefied, and is even less soluble in water than oxygen. It is incapable of sustaining life, but contains no poisonous properties. Hydrogen is never found free in nature, but exists abundantly in combination, forming one ninth by weight of water, and a considerable proportion of all organized substances. It is the lightest of all known substances, being 16 times lighter than oxygen and 14 1/2 times lighter than air; its density is placed at 0.0692 referred to that of air as unity, 100 cubic inches weighing about 2.14 grains.
