Christ Winterich, Defiance, O., has 

 now used the Holly electric circulator for 

 two years and says he would not be 

 without it in another cold wave for twice 

 its cost. It enables him to meet rapidly 

 changing weather conditions with ease 

 with his hot water system. 



TO REDUCE SMOKE. 



In a bulletin on ' * How to Bum Illinois 

 Coal Without Smoke," L. P. Brecken- 

 ridge says; 



There are many small plants that are 

 hand-fired which smoke badly. The con- 

 struction of many of these furnaces is 

 such that it is almost impossible to ope- 

 rate the plant without smoke. Still, 

 something might be done to reduce smoke 

 if the fireman exercised more care in 

 firing. Whatever can be done by the 

 fireman in the way of properly introduc- 

 ing the fuel into the furnace is just so 

 much gained, for the best method of 

 hand-firing for smokelessness is also the 

 best method for attaining economy. 

 There are three generally recognized 

 ' methods of hand-firing: (a) The Spread- 

 ing, (b) the Coking and (c) the Alter- 

 nate, The first is satisfactory and gen- 

 .erally used for anthracite; the second 

 for lroking^_.eaals^ and the last for noli- 

 coking coals. It is the alternate method 

 that is best suited to Illinois coals. This 

 method is described as follows: The 

 fuel bed area is divided into equal parts, 

 two, four,, or six, depending on the size 

 of the entire surface. The fresh coal is 

 fired alternately on one-half of these 

 areas at a time, at such intervals as may 

 be necessary to hold the steam pressure. 

 For small areas, first one-half the sur- 

 face of the fuel bed is covered and then, 

 perhaps three minutes later, the other 

 half. This method allows much of the 

 air supply to come through the bright 

 fuel bed, and thus become heated and 

 suitable for mixing with the highly vola- 

 tile content which is being rapidly driven 

 from the freshly fired coal on the other 

 side. Just because fresh fuel has been 

 spread over one part of the fuel bed, the 

 air most needed at that moment cannot 

 as easily flow through it, and another 

 part of the fuel bed should be left free 

 for its passage at that time. When the 

 fuel bed area is very large, some checker- 

 board system of firing may be adopted 

 which, when alternately fired and left 

 free for air passage, will result in a large 

 reduction in the amount of smoke pro- 

 duced by the too common method of 

 spreading the coal over the entire surface 

 at each firing. 



It must not be forgotten that a large 

 supply of warm air is needed immediate- 

 ly after fresh fuel is spread over a part 

 or all of the fuel, bed; this is best sup- 

 plied as just explained, but it may be 

 advantageous to provide for still more 

 air by leaving the fire doors open slight- 

 ly just after each "firing. There are sev- 

 eral devices on the market which provide 

 for an air supply over the fire, which are 

 turned on with the opening or closing of 

 the fire door, and which can be arranged 

 to close at the end of any desired time, 

 depending upon the rate of driving and 

 frequency of firing found desirable. The 

 firing of small amounts of coal at fre- 

 quent intervals produces less smoke than 

 firing large amounts at longer intervials. 

 The latter method, however, usually 

 proves less tiresome to the fireman and

COAL AT CHICAGO. 



The Black Diamond, authority in its 

 trade, says that "Chicago saw a conges- 

 tion of coal for practically all of the 

 winter up until two weeks ago, and then 

 there was just enough cold weather to 

 clean up the stocks on hand. Imme- 

 diately the trade plunged into another 

 period where the supply of coal is likely 

 again to glut the market. 



"Smokeless coal for the time being is 

 comparatively firm, because the amount 

 on hand has been reasonably well cleaned 

 up. The recent cold snap caused some 

 jobbers to telegraph to their producing 

 companies to increase shipments into Chi- 

 cago territory, and these are now on the
