Excerpt from How to Improve the Hot-Air Furnace Hot-air furnaces for house heating are used in such great numbers, especially the smaller sizes, that one would expect a considerable literature on the subject of their economical design, installation, and operation. As a matter of fact, there is much less to be found on this subject than on, steam and hot water house-heating equipment, largely because of the difficulty of measuring the output from a hot air furnace. The quantity of heat absorbed from the fire by either hot water or steam systems is rather easily measured by accepted methods, but it has proved a problem of some difficulty to as accu rately measure the quantity of heat absorbed by the hot-air furnace. Hence the problem has been much less attractive as a laboratory investigation than problems having to do with steam or hot-water apparatus. There is, however, a real need for a larger body of information about the performance of hot-air furnace installations than is now available. Mr. Baker's article shows how interesting such problems can be, how really worth while it is for a good engineer to give them careful and ingenious attention. The Bureau of Mines is glad to print such material, which will not only help many users of hot-air furnaces but will also tend to stimulate investigation in this fertile field.
