Peat fires like this are smouldering combustion.
Smouldering happens on the surface of the material and not in the gas like in the flaming combustion. Compared to flaming combustion smouldering combustion is slower, lower temperature (900 C) vs and flameless. Smouldering is typical for porous fuels like peat.
The burning is sustained by heat. The burning beat is little underground. The burning peat is insulated so that the heat does not escape and the smouldering can continue.
