Why does peat burn?

Peat fires

Peat has a high carbon content and can burn under low moisture conditions. Once ignited by the presence of a heat source (e.g., a wildfire penetrating the subsurface), it smoulders.

Why do they burn peat bogs?

What is peat burning? Peat burning is not actually burning of peat, it's burning of the vegetation that grows on top of peat. This is usually heather or grasses, such as purple moor grass. It has been done traditionally to provide new growth of heather (for grouse) or grasses (for sheep).

Does peat burn easily?

Peat has traditionally been used for centuries for cooking and domestic heating. These 'coal-like' lumps of peat are easy and clean to handle, light easily and can also be burnt alongside other fuels on multi-fuel stoves and open fires.

Why do the Irish burn peat?

' Peat has been an invaluable source of heat and energy throughout history in Ireland. It was found to be a useful alternative to firewood for cooking and heating throughout Ireland and other parts of the European continent.

Is burning peat worse than coal?

But peat is particularly polluting. Burning it for electricity emits more carbon dioxide than coal, and nearly twice as much as natural gas.

What is Irish turf? - Irish Peat and Turf Cutting

Is burning peat better than coal?

Peat is the most damaging fuel in terms of global warming; even worse than coal. It has a lower calorific value than coal (generating less energy per tonne when it is burned) and yet it produces higher CO2 emissions per unit, so it is the least climate-efficient way to produce electricity or heat in Ireland bar none.

Is peat dirtier than coal?

But peat, or turf, is one of the most polluting fuels in the world. It is more polluting, even, than coal, generating less energy when burned while producing more emissions.

Are there peat bogs in the US?

United States

Brown's Lake Bog - in Wayne County, Ohio, one of the few remaining kettle peatlands in the U.S. state of Ohio. It has a kettle lake, kame, and a floating sphagnum moss mat. Stillwater Bog - a sphagnum bog in Snoqualmie, Washington.

Is burning peat better than wood?

Peat has low atmospheric emissions when burnt compared to many fuels and it is clean and easy to handle. From as little as 20p per kg it is also one of the cheapest fuel products on the market today when compared with coal, soft and hardwood logs.

Why do bodies not decompose in peat bogs?

Organic material trapped below the mossy surface of intact peat bogs is starved of oxygen, creating an environment too hostile for the fungi and bacteria that would normally break down plants or bones.

Why should humans not destroy peat bogs?

Peat bogs are a very important store of carbon. We call them carbon sinks . If all the peat was removed and burned this would quickly release a huge volume of carbon dioxide into the atmosphere and contribute to the greenhouse effect.

Why should we not destroy peat bogs?

Why is bare peat a problem? Bare peat results in carbon dioxide being released into the atmosphere, contributing to worsening climate change. In the UK, 10 million tonnes of carbon dioxide are released into the atmosphere every year through damaged peatlands.

Is burning peat toxic?

The fine particles released from peat fires pose the greatest risk to your health. When these particles get into your eyes and lungs, symptoms of irritation such as coughing, wheezing and sore eyes are commonly experienced. As smoke levels decrease these symptoms will become less pronounced and eventually cease.

Do you dry peat before burning?

Cut peat should be dried before burning to reduce tar deposits. Peat should be burnt in the same manner as wood, on the flat base of the stove in a bed of ash. Doubles, Trebles and Cobbles may be burnt, do not use singles or coal dust (or “slack”).

What is the disadvantage of burning peat?

But the substance also has its drawbacks. Peat ignites very easily and smolders for an extremely long time, setting free huge quantities of carbon dioxide into the atmosphere.

Why is peat moss being banned?

The sale of peat moss has been banned for these reasons: Harvesting dries the peat moss emitting the stored CO2 (carbon dioxide) into the atmosphere where it persists for hundreds of years. Harvesting destroys ecosystem plants and animals' endemic to their geographic locations.

Where is the largest peat bog in the world?

Scientists have discovered the world's largest tropical peatland in the remote Congo swamps, estimated to store the equivalent of three year's worth of the world's total fossil fuel emissions.

Is peat banned in the US?

But the voluntary targets set there in 2011 to end the sale of peat in their home-garden products by 2020 have slipped by. Last December, a ban effective in 2024 was announced, with a 2030 timeline on products for commercial growers.

Do the Irish still burn peat?

Almost 14% of households do so, including 4% for whom it is a primary source of heating, according to an Environmental Protection Agency study. The European Commission has threatened to impose sanctions on Ireland unless it curbs peat cutting in special areas of conservation.

What is the cleanest fossil fuel resource?

Natural gas is a relatively clean burning fossil fuel

Burning natural gas for energy results in fewer emissions of nearly all types of air pollutants and carbon dioxide (CO₂) than burning coal or petroleum products to produce an equal amount of energy.

What is the purest coal ever?

Because of its high carbon content, anthracite is the purest kind of coal.

Why are peat fires so difficult to put out?

Once found, one problem to putting out peat fires is that peat soil repels water when it gets very dry, says Watts. Think of how water pools on top of the soil in a potted plant that has been neglected for too long. Water has to be able to break through the soil's surface to get to the underground fires.

What is the cleanest coal to burn?

Anthracite coal is a highly-carbonated fossil fuel that will generate the highest heat of all the fossil fuels available, and the low sulfur content in Anthracite makes it an extremely clean-burning fuel.

What is the longest burning peat fire?

"Indeed, the oldest continuously burning fire on Earth is the Burning Mountain in New South Wales, Australia, a large coal seam that has been smoldering for approximately 6,000 years," Rein said.

Why should we not use peat?

Peat releases huge amounts of stored carbon dioxide when it is harvested, which adds to greenhouse gas levels. Peat mining is effectively unsustainable – it grows back at just 1 mm a year.
