In 2018, coal-fired power plants accounted for just 28% of the total electricity produced in the U.S., while natural gas and oil's share increased to 35% and non-hydro renewable's share to 10%. This shift, which shows little sign of slowing, is creating both new opportunities and challenges for stakeholders.

and the valves required for boiler operation. Coal-fired plants are the most widely used power plant today. They involve the combustion of coal producing high pressure (typically 2400–3500 psig, ~165–240 bar) and high temperature (>500ºC) steam which is used to drive a turbine at synchronous speed (3000 rpm in countries such as the UK
