3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.
A large pulp and paper mill in the U.S. reached out to us for a major overhaul with new high-pressure section steam path components to derate their GE industrial steam turbine from 60 to 28 MW. They saw a performance improvement of ~6 MW in their main operating point on the same steam supply, and significantly reduced their water treatment ...
The outlook for coal prices in the United States. In the Annual Energy Outlook 2021 Reference case, the U.S. Energy Information Administration (EIA) projects that U.S. coal prices will generally increase each year through 2050, based largely on assumptions for the coal and electricity markets and industrial sector demand.

The new mills make steel by melting scrap or processed iron in electric furnaces, a production process that now accounts for about 70% of the steel made in the US. It is a low-cost process with fewer carbon emissions than making steel from iron ore. Melted in a coal-heated blast furnace. But the process is putting more pressure on the US junk ...
