A test program was conducted at the Holston Army Ammunition Plant near Kingsport, TN to evaluate the combustion of an anthracite-bituminous coal blend in a spreader stoker boiler designed for bituminous coal only. The test program was structured to evaluate different percentages of anthracite and bituminous in the blend at different operating loads on the boiler. Blends of 15, 22, 30, and 42% anthracite were combusted at loads of 62.5, 50, and 37.5% of the maximum continuous rating (MCR) boiler capacity. Stack testing and ash sampling were performed to monitor combustion performance, in addition to visually inspecting the ash bed. The testing disclosed no technical reasons why anthracite-bituminous blending could not be performed on a long-term basis to meet targeted Army anthracite consumption tonnages.
