The present disclosure relates to an integrated treatment method of two-stage submerged combustion evaporation for organic waste liquid, the organic waste liquid to be disposed flowing into two evaporation chambers in succession for two-stage submerged combustion evaporation. The two evaporation chambers are provided in one evaporation tank and communicate with each other at the bottom of the evaporation tank, the organic waste liquid enters a first evaporation chamber from a raw liquid inlet pipe, and the organic waste liquid flows from the first evaporation chamber to a second evaporation chamber during submerged combustion evaporation. The method has advantages of improving the evaporation concentration efficiency, reducing the numbers of evaporators and transport pipes of all sorts of gases and liquids and saving energy, saving the area occupied and the cost, while simplifying treatment process and facilitating operation management.

A thermochemical system & method may be configured to convert an organic feedstock to various products. A thermochemical system may include a solid material feed module, a reactor module, an afterburner module, and a solid product finishing module. The various operational parameters (temperature, pressure, etc.) of the various modules may vary depending on the desired products. The product streams may be gaseous, vaporous, liquid, and/or solid.

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.

In the disclosed solution sand to be cleaned is thermally cleaned by rotating the sand being cleaned in a large oven (1) by rotating the oven (1). Before cleaning, the sand may be pre-processed by crushing any lumps and cleaning the sand fraction by magnetic separation. Preprocessed sand to be cleaned and heat energy are fed (5) into the rotating oven. The oven (1) is set slightly inclined so that a second end of the oven (1) is lower than a first end. The inclination and rotating speed of the oven (1) as well as the feed amount of sand are adjusted, whereby the advancing speed of the sand may be adjusted, as well as the ratio of the sand being cleaned to the volume of the oven (1) kept as desired. The temperature of the oven (1) is monitored at the coldest area of the oven, which is substantially at the second end of the oven. The temperature of the oven (1) is adjusted by adjusting the amount of heat energy fed in. By means of temperature monitoring and knowing the advancing speed of the sand, it is also possible to determine the average temperature of the sand and adjust it as desired by adjusting the supplied heat energy. Finally, the cleaned sand is let run (12) from the second end of the oven (1).

A process of making a fuel product from a non-combustible high protein organic material such as a waste material. The high protein organic material is pulverized to a particle size whose particle size less than 2 mm. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying of the high protein organic waste material within the combustion chamber. Temperature and combustion reactions within the combustion chamber may be controlled by injection of steam within the combustion chamber.

The combustion system is provided with an oxyhydrogen gas supply structure (40) for heating the water supplied to the boiler (11) and also supplying an oxygen/hydrogen mixed gas, and a mixer (30) for mixing the superheated steam generated with the superheated steam generation device (20) and the oxygen/hydrogen mixed gas from the oxyhydrogen gas supply structure (40). The superheated steam is mixed with the oxyhydrogen gas and supplied to the combustion structure (50).

A heating apparatus for a fluid flow system having a fluid conduit includes at least one heater element and a support member within the conduit. The at least one heater element includes a resistance wire, a sheath, and an electrically insulating material. The sheath has a closed profile shape that extends along a tortuous path through the container body and surrounds the resistance wire along the tortuous path. The insulating material is disposed about the wire between the wire and the sheath. The support member restricts movement of the at least one heater element relative to the fluid conduit. The support member defines a corrugated geometry that follows the tortuous path while contacting the sheath along a majority of a length of the sheath. The support member increases heat transfer from the at least one heater element to a fluid flowing through the fluid conduit.
