FIG. 4—PROCESS OFCOMBUSTION OF COAL IN HAND-FIRED FURNACE This is not the rule in most plants. Engineers find theboiler room a hot and unattractive place in which tospend their time, and they have not been encouragedby having sufficient equipment (see Fig. 6) suppliedthem to permit them properly to measure all the opera-tions in the boiler room. Unfortunately the manage-ments have been satisfied with such practices. Firemen should understand the theory of combustionin the boiler furnaces as far as possible. Of coursethere is much that even specialists still have to learn asto the proper relation of furnace shape and volume,stokers and arches, and of the adaptability of all theseto the coals of various heat value, physical and chemicalcharacteristics, but a great deal of information isavailable. Obviously, to burn coal econ
