Abstract
Abstract For reasons of economy, increased capacity, and the possibility of improving operation when only inferior coals were available, the Kansas City Power & Light Company, in 1937, installed natural-gas burners in three of the chain-grate stoker-fired boilers at its Grand Avenue Station, to supplement coal firing. Later, additional boilers were equipped, the last two installations being made in 1941. Over the period of operation, the average use of gas at this station has represented 25 to 30 per cent of the fuel requirements. The reasons leading to the adoption of this combined firing system are outlined in the paper, as well as the details of the installations and the operating results achieved.
