基于多孔反应介质的数学模型，我们提出了一种新的表述和数值解决方案，用于解决由于低火成核位置的作用而引起的泥炭床着火问题。结果表明，在中等温度（T2≤≤750 K）下，原反应物的阴燃是由与森林火灾成核点的热质交换过程、泥炭的干燥和热解过程以及碳氧化物的氧化反应、泥炭高度和其床下水层的厚度决定的。
We propose a new statement and a numerical solution of the problem on ignition of a peat bed as a result of the action of the nucleation site of a low fire on the basis of the mathematical model of a porous reactive medium. It has been obtained that at moderate temperatures (T2 ≤ 750 K) the smoldering of the original reactant is determined by the processes of heat and mass exchange with the nucleation site of the forest fire, drying, and pyrolysis of peat, as well as by the oxidation reaction of carbon oxide, the peat height, and the thickness of the water stratum under its bed.
