Burning Washington Coals on Different Types of Domestic Stokers in the Same Hot-Water Boiler: Comparison with Hand and Oil Firing
From Purpose and Scope: "This bulletin presents the results of an investigation of domestic stokers at the Northwest Experiment Station of the Bureau of Mines. Previous publications have dealt with the burning characteristics of Washington coals on a domestic overfeed stoker, a clinker-type domestic underfeed stoker, and an ash-removal-type domestic underfeed stoker designed for burning anthracite. This report includes all the principal results obtained on the three domestic stokers tested and compares these results with those obtained on the same hot-water boiler by hand-firing and oil-firing."
