Bridgeport Paper - Discussion (continued) of Mr. Stetefeldt's paper on consumption of fuel in the Taylor gas-producer (see vol. xxiii., pp. 134 and 585)

lv. H. Blauvelt, Great Falls, Montana (communication to the Secretary): In his remarks on Mr. Stetefeldt's paper (Trans., xxiii., 587)) Mr. Goetz observes: " Trouble experienced with producers at Great Falls influenced me to try Taylor producers instead of those of Wellman. But recent reports show that the Wellman producers work better, besides coating nearly 50 per cent. less than Taylor producers of equal capacity. Indiana and Illinois coals cannot be used in the Taylor producers by reason of the large size and hardness of the clinkers which they form." I think that Mr. Goetz must have been misinformed regarding the work of this producer in Illinois. One of the large mauafacturing concerns in that State, the Illinois Zinc Company, situated at Peru, which uses a coal mined in the vicinity, tried one Taylor producer, some four years ago, in competition with those of an older type, which it had been using. As a result of this trial, the company has now thirteen Taylor producers, which have been in operation for about three years. A recent report from these works says that the Taylor producers have largely reduced the loss of coal through the grate, and have also improved the quality of the gas, as compared with that produced from the same coal in the producers of the older type. This Illinois coal is, perhaps, the worst in the country for making gas; since, besides containing from 20 to 40 per cent. of ash, it carries a large quantity of pyrites, so that the clinkers are large and extremely hard, and the capacity of the producer is most severely tested.
