Fuel preparation plant performance and modifications, April 1983-March 1984

OSTI ID:5638262

The Fuel Preparation Plant processes raw coal by crushing, drying, cooling and screening and mixes this in a predetermined ratio with a sulphur absorbing agent (dolomite or limestone). This mixture is used as feed for the Pressurised Fluidised Bed Combustor at Grimethorpe. The plant contains two systems for the pneumatic conveying of solids: one for transport of the prepared raw coal to an intermediate storage silo and one for the transport of blended coal/sorbent mixture from the Fuel Preparation Plant to the Main Facility building. This report covers the period from April 1983 to March 1984, which completes this phase of the facility's operation. New systems for pneumatic conveying and a new primary screen for raw coal were commissioned and operated. Details of the operation and subsequent minor modifications are included. Existing operation/equipment problems which were still experienced after April 1983 were mainly solved and the system was brought up to a standard where coal processing became satisfactory. 2 refs., 21 figs., 3 tabs.
