โœฆ Synopsis

In order to determine the elemental contents of carbon, hydrogen, sulfur and nitrogen in coal, a one-step method for combined combustion and gas absorption was developed. Following combustion in 02 in several furnaces, the gases are sent to separate absorption tubes for selective removal of gases. After reaction, the tubes can be weighed to obtain data on increased weight resulting from the absorption of gas components.

This paper describes a study of the transportation of pulverized coal. The results showed that this cannot be evaluated exactly by rest angle, but by the injection amount per unit time. The transportation characteristics of pulverized coal are related to the variety and nature of the finished coal.
