Britain forced to fire up coal plant amid record power

Britain forced to fire up coal plant amid record power

Sep 08, 2021 The Government plans to phase-out coal-fired power by 2024 in an effort to slash carbon emissions. Most coal-fired power stations have closed, but some remain available to help meet demand – particularly in emergencies. Wind power now generates about 20pc of UK electricity across the year but varies hugely day by day.

Assessing and managing spontaneous combustion of coal

Assessing and managing spontaneous combustion of coal

Most underground mine explosions are due to a build-up of methane which is then ignited by a spark, usually from a piece of equipment or a friction event. However, spontaneous combustion or heating of coal in situ can also act as an ignition source which, together with elevated methane concentrations, will result in a mine explosion.
