Abstract:
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.
Abstract:
An ash melting system of the present invention includes a slagging combustion furnace (10) for melting ash into molten slag; and a slag separating apparatus (50) for bringing the molten slag (121) discharged from the slagging combustion furnace into contact with slag cooling water (152) to produce water-quenched slag (122), and separating the water-quenched slag from the slag cooling water. The ash melting system further includes a gas blowing means for blowing air or inert gas (132) between a slag discharge port (14) of the slagging combustion furnace and the surface of the slag cooling water.
Abstract:
A high temperature gas reforming cyclo-incinerator, using reformed water and strongly swirling inlet air in its interior to burn up wastes. The incinerator has a dust collecting structure designed to almost completely remove circulating dust and other harmful impurities from air strongly swirling in the incinerator and discharge clean air to the atmosphere. Internal and external lower tubs have substantially larger diameters than those of internal and external upper tubs, thus effectively burning up a large quantity of wastes at one time. The incinerator is also provided with a flow rate control fan unit separate from a main fan unit, thus controlling the amount of inlet air as desired and allowing a user to control the incineration rate of wastes in the incinerator.
Abstract:
A waste disposal system (10) which provides for the destruction of solid and liquid waste materials, through a controlled and monitored flow, from the loading of the material to be processed to the expulsion of clean nontoxic and sterile air and inert solid residue. The system includes; a waste loading module (30), a shredding module (33), an injection module (34), a first combustion chamber (40), a second combustion chamber (50), a first cooling module (60), an electrostatic module (701), a reducing catalyst module (70), an oxidizing catalyst module (80), a liquid filtering module (90), a neutralization module (100) and a second cooling module (101).
Abstract:
A method and apparatus for burning material having a primary burner in the form of an elongated cylinder, the ends of the cylinder closed with stationary end walls. The cylinder is rotated about its longitudinal axis which is horizontal. A ram material inlet is provided in one end wall for compressing and feeding material into the cylinder. An air inlet conduit introduces air into the cylinder to promote burning of the material in the cylinder as the cylinder rotates. The combustion cylinder is maintained by an exhaust fan and air control valves at a pressure below atmospheric. A secondary afterburner is provided adjacent the primary burner that receives combustion gases from the primary burner. A cyclonic separator is positioned downstream of the gases burned in the afterburner. A programmable logic controller connected to air valves and sensors monitors the combustion process to sustain maximum combustion efficiency at temperatures above 1700 degrees Fahrenheit.
Abstract:
A simplified energy producing system that utilizes natural animal waste and/or by-products and converts such waste into a usable clean energy source. The system incorporates a grinder/dehydration system, waste transport, a holding container, fuel air regulator, and a novel combustion heat regulator in combination. Thus, after the waste has been treated, combusted and incinerated, intense heat is produced that is usable via heat exchange for production of electrical energy and also a fine fly ash is produced usable for environmentally friendly purposes.
Abstract:
A low-temperature thermal desorption (LTTD) system remediates highly contaminated soils. The system (1) reduces the concentration of vaporized contaminants exhausted from the primary treatment unit (PTU) and (2) precisely controls the concentration of vaporized contaminants exhausted from the PTU so as to permit the safe oxidization of contaminants in a secondary treatment unit without oversizing the secondary treatment unit or the baghouse. The concentration of vaporized contaminants exhausted from the PTU is reduced by drawing the vaporized contaminants into a low-pressure region of the PTU so as to contact the burner flame and by supplying this area of flame contact with a modulated supply of air to oxidize a designated portion of the vaporized contaminants within the PTU. The concentration and temperature of the remaining vaporized contaminants are controlled by monitoring the concentration of the contaminants in the gas stream exhausted from the PTU, by calculating a lower explosive limit (LEL) of the contaminant concentration, and by providing a modulated supply of heated dilution air to the gas stream to precisely reduce contaminant concentration levels in the gas stream to a desired percentage of the calculated LEL.
