Abstract
A chemical heater combines cellulosic material and a hypochlorite salt in the presence of water for exothermic reaction. Although sodium hypochlorite may be used, calcium hypochlorite is the preferred hypochlorite salt as a reactant. The preferred cellulosic material is particles of cotton plants, in particular lint fibers recovered from gin trash, or non-lint, lignocellulose particles. The lignocellulose particles are preferably soaked with water prior to addition of the hypochlorite salt. Each subsequent addition of similar amounts of the hypochlorite salt to the soaked lignocellulose particles results in a substantially equivalent exothermic reaction, until cellulose in the lignocellulose is exhausted.
