The gas swirling state determination system (10) determines the quality of the swirling state of gas that swirls around the central axis. The gas swirling state determination system (10) includes an imaging device (39), an information processing device (11), and a display device (42). The imaging device (39) captures swirling gas from a direction along the central axis to acquire a still image. The information processing device (11) includes a calculation unit (40), a smoothing unit (41), and a determination unit (43). The display device (42) displays a determination result.

A boiler apparatus for waste incineration includes a combustion chamber having a waste inlet formed on one side and combustion spaces for incinerating the introduced waste. Air injection pipes are vertically spaced apart from one another from a lower part of the combustion chamber, extend along the circumference thereof, and have injection holes to inject air toward the center of the combustion spaces. An air supply unit supplies air to each of the air injecting pipes separately, in response to a control signal. Temperature sensors are mounted in the combustion spaces in respective stages vertically divided on the basis of the air injecting pipes, to measure a combustion temperature of the combustion space within the combustion chamber. A control module controls operation of the air supply unit, to control an injection amount of air fed to the combustion space according to a combustion temperature measured by each temperature sensor.

Methods and systems are provided for two-stage treatment of contaminated particulate material, such as soil, sediment, and/or sludge. The methods and systems utilize a thermal desorption process combined with a smoldering combustion process. The contaminated particulate material is first exposed to thermal desorption at high temperatures (e.g., greater than 150° C.) to form a heated contaminated particulate material. Next, a smoldering combustion process is initiated by introducing a combustion-supporting gas. The combined process can take place in the same or different treatment units. Treating the particulate material with a thermal desorption process prior to a smoldering combustion process enhances the completeness and throughput compared to operating these processes separately.

A ground supported single drum power boiler is described combining a refractory lined and insulated V-Cell floor; refractory lined and insulated combustion chamber; integrated fuel chutes configured to pre-dry wet solid fuel; top mounted fuel bin; internal chamber walls; configurable combustion air systems; and a back pass with after-burner ports and cross flow superheaters. The boiler can be configured in pre-assembled modules to minimize the field construction time and cost. An alternative embodiment is adaptable as a gasifier.
摘要:
A furnace apparatus to incinerate solid waste comprises a chamber, a solid waste feed inlet, air inlet pipes, and air outlet pipes. The chamber includes an upper pyrolysis section and a lower combustion section, and the solid waste feed inlet is positioned at an upper portion of the chamber to feed solid waste to the lower combustion section. The air inlet pipes receive air for combustion of the solid waste within the lower combustion section. The air outlet pipes exhaust combusted air from the lower combustion section, where multiple magnets are operably attached on the air inlet pipes and the air outlet pipes. The paramagnetic oxygen present in the received air is concentrated via the magnets, and the concentrated oxygen is introduced into a plasma generated within the combustion section to accelerate the combustion process, and to oxidize toxic matter present in the solid waste.

A device for converting a fuel including solid components, known as a solid fuel, into a gaseous fuel, includes a pyrolysis zone (2) for pyrolyzing solid fuel, having pyrolysis elements that are capable of decomposing the solid fuel into a pyrolysis gas and into a solid pyrolysis residue, known as coke, and a combustion zone (3), which is distinct from the pyrolysis zone (2), for burning the pyrolysis gas and having combustion elements (31, 32, 33). The device also includes elements for circulating pyrolysis gas from the pyrolysis zone (2) to the combustion zone (3), which is surrounded by the pyrolysis zone (2).
摘要:
A combustor for burning waste material includes a horizontally extended combustion chamber through which a mixture of waste material and air is introduced under pressure tangentially for establishing a vortical movement of the waste material toward one of the end walls. The waste material is ignited during its vortical movement. A second discharge port extends for discharging from the chamber non-combustible material entrained in the outer region of the vortex. The discharged material is conveyed through a conduit to a separator which separates the discharged gases and solid material. A secondary air manifold supplies air through controlled and automated dampers at portals positioned at intervals along the length of the chamber. An adjustable baffle is mounted on the flue adjacent its open end for deflecting outwardly toward the side wall solid material which moves from adjacent the one end wall toward the open end of the flue. A recuperator is mounted externally to the chamber on the exhaust flue, supplying heated air to the secondary air manifold and to the primary air and waste feed intake. Additionally, control means are provided for the use of specialized sensors to monitor the temperature, air flow and volume of the chamber, integrated into a process automation system that allows for control of individual components, stages, regions, as well as the entire process.

摘要:
An apparatus for processing fly ash comprising a heated refractory-lined vessel having a series of spaced angled rows of swirl-inducing nozzles which cause cyclonic and/or turbulent air flow of the fly ash when introduced in the vessel, thus increasing the residence time of airborne particles. Also disclosed is a method of fly ash beneficiation using the apparatus.
