Minnesota Power and the Minnesota Department of Natural Resources conducted the Industrial Scale Peat Use Demonstration in 1985 at the Syl Laskin Steam Electric Station. The Station is located near Hoyt Lakes, Minnesota. The two unit station commissioned in 1951 was designed to fire bituminous coal. Its current capacity is 88 MW (2 units of 44 MW each) fired with western subbituminous coal. The Demonstration focused on two areas: the Syl Laskin Station and the Fens Bog areas northwest of Cotton, Minnesota. Two past producers were contracted to produce and stockpile up to 25,000 tons of sod peat. One trucking company was contracted to transport the peat to the Station, where it was received, mixed with coal in various proportions, and burned between June 1985 and January 1986. The results of this demonstration are provided in this report. 9 figs., 10 tabs.
