A passive vortex formed or induced from a temperature difference across a cavity or void aggregates and supports a horizontal flow over the top of the cavity. A cavity of a suitable depth and width exhibits a small difference in temperature, or heat source, along the sides or bottom of cavity. A resulting convective flow tends to form a rising current along a warmer side, and a complementary downward current on an opposed side of the cavity. The formed vortex tends to draw the cooler downward flow across the warmer, heated surface, enhancing the vortex flow. The vortex aligns with a horizontal flow across the top of the cavity as the upward current complements the downward current on an opposed side of the cavity. A plurality of adjacent cavities tend to align with an aggregate horizontal flow contributed from each cavity.

A volatile liquid storage container has combustion resistance properties from a flexible sock or tube constructed of fire resistant fibers coupled to a neck of the storage container to prevent flame flash-back into the storage container. The storage container defines an enclosed volume having an orifice in the container material leading to a neck for pouring and filling the enclosed volume for exchanging the contents therein. The tube is elongated and surrounds a circumference of the orifice for engaging any ignition source entering through the orifice. The flexible nature of the tube or sock allows it to extend to an opposed interior surface of the enclosed volume, and ensures that the tube or sock is immersed in the fluid for encircling any ignition path to the volatile liquid without interfering with an ability to pour or refill the container.

A system, device and method for deployment of one or more dust accumulation sensors receives a baseline measurement associated with no accumulation of dust in a target environment, receives a time-elapsed measurement associated with positive accumulation of dust in the target environment, determines a quantity of accumulated dust in the target environment based on the baseline measurement and the time-elapsed measurement, generates a spatial dust deposition distribution for the target environment based on the determined quantity of accumulated dust and determines a deployment for one or more dust accumulation sensors for the target environment based on the spatial dust deposition distribution.

The present disclosure provides devices and methods for cleaning up or burning spills of burnable materials in situ. In some embodiments, a system for burning a burnable material comprises a base having a first side configured for placement on a surface with a burnable material and a second side; and a plurality heat conducting members extending from the second side of the base.

A toxic waste incinerator is capable of enhanced combustion of hazardous waste (oil contaminated sand, human waste, garbage, etc.) utilizing immersed non-combustible and thermally conductive objects for increasing heat feedback from the flames to the unburned fuel, while air inlets are used to optimize the air entrainment rate to enhance the burning efficiency. The burning rate of a fluidic mass such as a sand-oil mixture is enhanced using immersed conductive objects (copper rods) which enable rapid heat-up of the flame exposed to the upper surface of the rod and transmits heat back into the sand. Consequent conduction of heat to the porous media through the lower portion of the immersed rod significantly increases vaporization and therefore the burning rate. Incineration may be performed on a transient, exigent basis as with hazardous waste and oil spills, or as part of a permanent fixture for receiving an ongoing waste stream.

Method and apparatus for waste combustion

Methods and systems for clean-up of hazardous spills are provided. In some aspects, there is provided a system for burning an water-oil emulsion that includes an enclosure configured to hold a water-oil emulsion; one or more conductive rods disposed throughout the enclosure, each rod of the one or more roads having a heater portion to be submerged in the water-oil emulsion and a collector portion to project above the water-oil emulsion, wherein the collector portion is longer than the heater portion; and a delivery system for supplying an water-oil emulsion to the enclosure, the delivery system is configured to maintain a constant level of the water-oil emulsion in the enclosure as the water-oil emulsion is burned. The enclosure may further include one or more adjustable air inlets.

A measurement system includes a plurality of thermocouples, where the plurality of thermocouples is located in a support component and includes at least three groups of thermocouples. The at least three groups of thermocouples can also include one thermocouple shared by the each group of thermocouples. A distance between two thermocouples from each of the at least three groups is selected to enable measurement of temperature/flow field features of a predetermined characteristic length.
