Estimating the term…
The burner preferably exclusively burns substantially explosible solid fuels and preferably has instant ON-OFF thermostat control, wastes no energy preheating the enclosure or external air supply, achieves stable combustion the moment the powder-air mix is ignited in our burner, is used in the upward vertical mode except for oil burner retrofits, burns a solid fuel in a single-phase regime as if it were a vaporized liquid or gas, is designed to complete combustion within the burner housing itself rather than in a large, high temperature furnace enclosure which it feeds, has an ultra-short residence time requirement, is a recycle consuming burner with self-contained management of initially unburned particles, is much smaller, simpler and lower cost, has a wider dynamic range/turndown ratio, is more efficient in combustion completeness and thermal efficiency, and operates with air-fuel mix approximately at the flame speed.
A burner for combustion of an explosible powdered solid fuel, comprising:
A burner system for combustion of an explosible powdered solid fuel, comprising:
A furnace for heating by combustion of an explosible powdered solid fuel, comprising:
A method of combustion of an explosible powdered solid fuel in at least one burner comprising an enclosure having an inlet end and an open exhaust end, a moving stream of a dispersion of particles of the powdered solid fuel in an oxidizing gas at an equivalence ratio in the explosible range downstream of the inlet nozzle, the particles having a size substantially in an explosible size range, and an ignition source downstream from the inlet nozzle for igniting the moving stream, the method comprising:
