Why US Coal Production Collapsed to Lowest Level since 1981

Jun 13, 2016 · Fracking for natural gas created a “glut” in the US, starting in 2009. The price collapsed to ludicrously low levels, finally sending a number of specialized natural gas drillers into or near bankruptcy in 2015 and 2016. Coal, which competes directly with natural gas, got hit too. And the Combined-Cycle Gas Turbine (CCGT) arrived in the 1990s.

I note that due to its burning low sulfur coal, such condensables should be low at Unit 3, leading to a lower MOT than at many SCRs that currently operated in the US coal fleet burning high-sulfur coals. To account for the MOT, I assumed that SCR would not be effective until a threshold load was reached at Unit 3 – typically 30%.

1. Introduction - Hindawi

This can be an issue for the salability of the coal since power plants prefer coals that are easy to grind. A possible mitigation for the low grindability is less grinding, if the coal could be burned at a coarser grind without impacting power plant performance. The rank and volatility of the coal are key to combustion.

Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. 1.9.After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
