Smouldering combustion of peat with various permeability at natural convection of oxidizer

Abstract

The regularities of smouldering combustion of peat with different permeability under conditions of natural oxidant convection were experimentally investigated. It is shown that as the permeability of peat samples increases, the peak temperature increases from 500 to 900 °C, and the spread rate increases from 8 to 80 mm/h, and oxygen is consumed more fully with increasing concentration of monoxide and carbon dioxide in gaseous products.
