If correct methods meth-ods were generally understood and applied throughout the country, the same heating service could be obtained ob-tained with one-half the fuel and there would result a saving of $2,000,-000 $2,000,-000 a day. These are conclusions reached as a result of research by the United Stntes bureau of mines, in cooperation co-operation with other agencies and with other data assembled by Samuel S. Wyer, associate in mineral technology, tech-nology, of Smithsonian institution, ln an educational program of resource conservation. It is pointed out that the urgent need In this country's fuel crisis is not for more research work, but for a quick and wide diffusion aud immediate imme-diate application of facts already known. Among these as set forth are: Anthracite, although a natural monopoly from a geographical viewpoint, view-point, is not a monopoly from the point of use, since "man-made anthracite" that is, coke can easily be made to take its place. Furthermore, the small sizes of anthracite representing 28 per cent of the total and now sold to the steam trade at low prices could easily be used ln the homes with, proper utilization methods. Bituminous coal should never be used In its raw state. Many principles are advanced for the guidance of the fuel user. For instance, in-stance, combustion (that is, burning) of every fuel is the chemical combustion combus-tion of the Ingredients ln the fuel with oxygen of the air. Different fuels require different quantities of air and applied ln different ways. "The burning of fuel with perfect combustion will produce carbon dioxide diox-ide the same substance that is exhaled ex-haled from the lungs and water vapor," continues Mr. Wyer's paper. "If the combustion is not perfect, carbon car-bon monoxide a poison and con-denslble con-denslble vapors and smoke will be formed. No heating device has or can be made that will absorb its combustion combus-tion products, hence they must be properly removed from the house by adequate flues. An opening should ba provided at the base of all chimneys for occasional cleaning. Solid fuels require longer connections than gas or oil. When bituminous coal is used, horizontal sections of flue pipes require re-quire frequent cleaning. "Tests show that ashes frequently contain 50 per cent of carbon. This Is because the grates do not receive proper attention. In shakltujgrates. . stop when the fire glow froiu"!fubve appears and before live coals go into the ash pit. Never leave ashes under the grates after shaking. Remove at once, as this will protect grates and give better circulation of air. |
