Disclosed are methods and systems for producing a gas from a combustible material. In particular, disclosed are methods and systems for batch-type production of a gas from a combustible material. The methods and systems include igniting at least a portion of the combustible material loaded in the sealed containment structure to form a thermally affected layer, wherein the step of feeding the oxidant into the sealed containment structure is carried out so that conversion of the combustible material to a gas at one point in the sequence is initiated prior to complete conversion of the combustible material at a previous point in the sequence.

Disclosed is a combustion machine, including: a hopper, a drying mechanism and a combustion mechanism. The hopper is configured for storing materials and conveying the materials to the drying mechanism. The drying mechanism includes a conveying mechanism and a drying chamber, and the conveying mechanism is connected with the hopper and conveys the materials in the hopper to the drying chamber. The combustion mechanism includes a combustion chamber connected with the drying chamber via a material conveying pipeline, and a fire outlet pipe arranged in the combustion chamber and used for outputting flame. A hot air pipeline is connected between the combustion chamber and the drying chamber, and a first exhaust fan is arranged in the hot air pipeline.

A method and device for drying wood chips to be used as raw material for a gas-generating reactor, the device being disposed between the storage for wood chips and the reactor. Product gas of the reactor is at least partially used in a block-type thermal power station (BHKW), and hot air from the housing of the block-type thermal power station is used to heat and dry wood chips in a drying hopper which has at least one outlet for the cooled humidified air. The wood chips enter the drying hopper through a first air-tight lock and exit the drying hopper through a second air-tight lock.

Methods and apparatuses can be configured to facilitate sorting of paper from garbage and/or single stream recycling and subsequently process that separated paper to remove the contaminants from the paper so that the paper is in an acceptable condition for recycling. In some embodiments, the apparatus and method may utilize at least one dryer device that is configured to heat the paper without combusting the paper to remove water from the paper. The dryer device can also be configured to mix the paper as it is dried while also removing particulate contaminants off of the paper to clean the thrown away paper sufficiently so that the paper is in a condition that is acceptable for recycling into a paper product (e.g. a cardboard box, paper plate, sheets of paper, etc.).

The present invention relates to a method and system for torrefaction of biomass and combustion of generated torrefaction gases. The torrefaction gases released from the biomass during the torrefaction reaction are withdrawn from the reactor and into a first burning zone. A secondary stream of air is introduced to the first burning zone to combust the torrefaction gases whereupon hot flue gases are obtained. Part of the hot flue gases are directed to a mixing unit. The rest of the hot flue gas is directed to a second burning zone for complete combustion of the flue gases. The fully combusted flue gases obtained in the second burning zone are directed to a heat recovery unit where the temperature of the flue gas is decreased. Part of the cold flue gases are directed to the mixing unit where it is mixed with the hot flue gases such that a stream of cooled flue gases is obtained. The stream of the cooled flue gases are diverted into the torrefaction reactor for direct heating of the biomass.

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 continuous process of the present invention is intended to obtain dry biomass from two treatment steps by drying organic waste. The waste previously sieved and crushed waste are dumped into a first dryer, inside of which temperatures are between 280? C. and 300? C. at the inlet thereof and between 90? C. and 100? C. at the outlet, then passing to a conveyor belt where at room temperature a partial cool-down occurs and the waste is dumped into a second dryer inside of which the temperatures are between 180? C. and 200? C. at the inlet and between 75? C. and 85? C. at the exit, completing the process, during which the interior of the dryers is maintained in negative pressure through exhaust flow and the oxygen content is kept between 5 and 7%.

A combustion kiln system, comprising: a pre-heating chamber which is supplied with waste product; and a combustion chamber which receives the waste product from the pre-heating chamber and in which the waste product is incinerated; wherein the pre-heating chamber heats the waste product to remove moisture from the waste product prior to transfer to the combustion chamber.
