A Locomotive That Burns 

 Pulverized Coal 



OUR modern locomotives are vo- 

 racious creatures. To fire one of 

 them — tlie Twentieth Century 

 Limited, for instance — is a task gradu- 

 ally approaching the superhuman. The

lignite and peat, are as productive of 

 economic results as the larg-er and better 

 grades of coal. Some ot the products 

 mentioned are unsalable and ha\e been 

 liirown away as waste, so the great

only remedy, according to railroad men 

 themselves, lies in the utilization of 

 pulverized coal. Of only comparatively 

 recent date, however, have appliances 

 for burning powdered fuel or coal-dust 

 in loconiotive fire-boxes been effectively 

 developed. The results have been en- 

 tirely satisfactory, effecting a saving of 

 from fifteen to twenty-five per cent of 

 fuel and untold labor. 



This economy is possible because any 

 solid fuel which in a dry, pulverized state 

 has two thirds of its content combustible 

 will be suitable for steam-generating 

 ])urposes. This means that such ordi- 

 nary coal products as dust, sweejiings, 

 culm, screenings and slack, and e\en 



saving eftcctcd is apparent. The total 

 cost to prepare pulverized coal is some- 

 thingless than twenty-five cents a ton, and 

 the preparation is not at all complicated. 

 The coal must be dry and groundto a fine- 

 ness so that it will pass through a one- 

 himdred or two-hunilred mesh screen. 

 'I'his is all the preparation necessary. 



There are three railroad lines which 

 have locomotives fitted with a successful 

 apparatus to burn coal-dust. These are 

 the New York Central, the Chicago and 

 Northwestern and the Delaware and 

 Hudson. The last-named system has 

 l^robably the largest pulverized fuel- 

 l)urning locomotive. Its tractixe effort 

 is about si.xty-three thousand pounds.
