Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ...a slower rate of combustion and less smoke production. It has taken a long time for ordinary people to learn and know that smoke issuing from a chimney is so much coal wasted in the air (without counting its ill effects), and every sack of soot the sweep takes away represents, in its compact condition, about three times the volume of coal. Most intelligent people now know this. The sweep, by the way, is an individual whose presence more inclines a lady towards hot water heat than any verbal argument can. The faults of this grate, Fig. 154, are: --(a) The height of the fire above the floor line does not permit the heat to be felt at the floor level, where it is needed, and where it can give the best general results. A warm floor line counts for much, if it is not everything, in rooms heated by fire grates. The construction of the fire-box is not of such form as will allow heat to flow to or towards the floor line. (6) The form of the fire-box is not such as will project or deflect heat, into the room, but, on the contrary, it affords every facility for more than half the heat to be projected or pass into the chimney. (e) The design of the fire-box does not provide for perfect combustion, nor even economical combustion ("slow combustion," as we call it, and as it is intended to be). Without extravagant coal consumption no useful degree of heat can be obtained in the room. (d) The wide area over the fire at the mouth of the chimney favours a poor draught in the chimney, a cooler and more rapid fouling chimney, and many minor ill results. No part of the opening above the fire-box contributes to the efficiency of the grate, but decidedly the reverse. (e) The fire-box is usually of iron, either wholly, or with fire-brick back and iron sides....show more
