1. The method of making portable personnel heating apparatus, said method comprising the steps of:

  • providing a fuel element comprising carbon;

    providing a priming device for said fuel element including a sheet of cellulose material;

    treating said sheet of cellulose material with catalyzing and oxidizing agents;

    drying said sheet of cellulose material and subsequently placing said sheet on said fuel element,characterized in this that during the treatment step said sheet of cellulose material is during a first time period treated with a first solution containing a catalyzing agent including manganates and permanganates such as salts of alkali metals including potassium (KMnO4, K2 MnO4),wherein said cellulose material is soaked in said first solution for at least fifteen minutes, said first soaking solution having a temperature between sixty and ninety degrees centigrade and containing an active catalyzing material in the range of from 0.1 and 5, said active catalyzing material being dissolved in water,followed by treatment of said sheet of cellulose material during a second time period with a second solution containing an oxidizing agent including inorganic oxidizing salts chosen from the anion groups of chlorates, perchlorates and nitrates, including ammonium perchlorate (NH4 ClO4),wherein said cellulose material is soaked in said second solution for at least ten minutes, said second soaking solution having a temperature between sixty and ninety degrees centrigrade and containing at least twenty parts by weight of said oxidizing agent to one-hundred parts of water and wherein said sheet of cellulose material being comprised of suphite cellulose.
