Smoldering Combustion and Ground Fires: Ecological

Although fires in wetlands would seem to be rare or impossible by definition, these ecosystems do occasionally experience fire. A common feature of fires in wetlands is smoldering combustion in organic soils, such as peat and muck. Increasing occurrence and size of these events from the Arctic to the tropics has been matched by increasing research interest, yet our …

Peat harvested in the Midlands supported a peat-fired power station at Portalington (built in 1950). In 1956, a coal-fired generation station was built at Arigna in Co Leitrim, fuelled by indigenous coal. Between 1950 and 1967, sod peat stations totalling 117 MW and milled peat stations with a combined generation capacity of 290 MW were built.
