ORGANIC MATTER DEGRADATION DEVICE
20210164654 · 2021-06-03 ·

An organic matter degradation device has a furnace and a gas supply device. The furnace has a furnace chamber. The gas supply device has a gas supply tube and a negative ion generating device. First branch tubes are disposed on the gas supply tube axially, and second branch tubes are disposed on the first branch tube. A first pipeline of the second branch tube is disposed horizontally, the first pipeline is communicative to the first branch tube via the second pipeline, and the negative ion generating device is installed on the first pipeline. The negative ions generated by the negative ion generating device can pass the first pipeline and directly enter the furnace chamber, which decreases the resisting force applied to the negative ions, and increases the negative ion flow kinetic energy.

TWO COMPONENT CHAR AND BIOCHAR COMBUSTION/PYROLIZATION SYSTEM
20210148570 · 2021-05-20 ·

A combustion/pyrolization system for generating at least one of char and biochar comprising an upper base frame supporting a combustion/pyrolization housing, and the combustion/pyrolization housing having both an open top end and an open bottom end. A char collection bin defining a collection chamber therein and a perforated grate normally covering the open top end of the char collection bin. The perforated grate being sized so as to permit desired sized char and/or biochar to pass therethrough into the collection chamber. The open bottom end of the combustion/pyrolization housing of the upper base frame is movable into an engaged position where the combustion/pyrolization housing partially receives and surrounds the perforated grate and defines a combustion/pyrolization chamber for receiving and consuming feed material. The upper base frame is movable out of engagement with the perforated grate to facilitate movement of the perforated grate and removal of the generated char and/or biochar.

Portable combustion system with first and second air sources
10948183 · 2021-03-16 · ·

A combustion/carbonizing system which comprises a base frame and a combustion chamber frame which is pivotably attached to the base frame. The combustion chamber frame defines an open top combustion chamber having a bottom perforated plate. A plenum is formed below the perforated plate for collecting biochar which passes therethrough. A first source of combustion air is supplied across the top of the combustion chamber while a second source of combustion air passes through the perforated plate into the combustion chamber. The combustion/carbonizing system is capable of operating in a continuous manner for combustion wood or waste material to the desired degree required by the end user for the purpose of reducing the volume of the material as well as the associated emissions while generating valuable char and boichar as an end product. For some applications, the combustion/carbonizing system may be operated to combust completely the wood or waste material.

Portable combustion/pyrolization system with first and second air sources
11054134 · 2021-07-06 · ·

A combustion/pyrolization system comprising a combustion/pyrolization chamber supported by the base frame, and a perforated grate forms a bottom surface of the combustion/pyrolization chamber and facilitates passage of char and boichar therethrough. The combustion/pyrolization chamber is open along at a top and an air manifold supplies a first source of combustion air across the top of the combustion/pyrolization chamber to form an air curtain. A char collection/transfer chamber is located below the perforated grate for collecting at least the char and boichar that passes therethrough, and a conveying mechanism transfers the char and boichar out of the combustion/pyrolization system for collection and use. An air plenum chamber cools the char collection/transfer chamber such that the supplied secondary air becomes heated, and the heated secondary air flows into the char collection/transfer chamber and through the perforated grate into the combustion/pyrolization chamber to provide secondary combustion air.

Method for Mitigating Acid Rock Drainage Potential through the Smoldering Combustion of Organic Materials

Methods are provided for the removal of sulfur and other ARD/AMD-generating materials through the smoldering combustion of an organic material. The methods comprise admixing an ARD/AMD-generating porous matrix material with an organic material to produce a mixture, exposing the mixture to an oxidant, and initiating a self-sustaining smoldering combustion of the mixture. Additional embodiments aggregate the organic material or ARD/AMD-generating porous matrix material or mixture thereof in an impoundment such as a reaction vessel, depression or matrix pile. Further embodiments utilize at least one heater to initiate combustion and at least one air supply port to supply oxidant to initiate and maintain combustion.
