Method for generating heat energy by intermittent smoke charge combustion

Claim 1

An intermittent process of overall low temperature operation for producing and utilizing thermal energy, said process comprising: (a) intermittently forming a smoke charge containing a mixture of an internal phase of a dispersion of fine solid particles and an external phase of air; (b) said solid particles being composed of slowly igniting organic material selected from the class consisting of agricultural, fossil, vegetation, and resinous materials; (c) said particles having an average diameter in the range of from 1 micron to 200 mesh; (d) said smoke being of at least atmospheric pressure and having a minimum concentration of at least 25 ounces of said solid particles per 1000 cubic feet of air at atmospheric pressure; (e) introducing said smoke charge, while maintained substantially at said atmospheric pressure, into a chamber; (f) intermittently energizing said smoke charge, while initially under said substantially atmospheric pressure within said chamber, with an electric current having an energy of at least 15 millijoules in order to cause exploding of said smoke charge of limited duration and at high temperature, the intermittency of said energizing and of said exploding of said smoke charge being of sufficient lengths to enable substantially complete dissipation of heat generated by said exploding into a heat exchange system; (g) powering an appliance with thermal energy generated by said exploding and transmitted through said heat exchange system; (h) and scavenging the residue of said energizing and exploding from said chamber.
