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.

Energy is generated from cellulosic biofuel waste streams, specifically a lignin filter cake and a waste syrup, by combusting these waste products in a fluidized bed combustor under specified conditions. The heat and steam generated can be used to generate electricity and/or in cellulosic biofuel production processes.

Embodiments of apparatuses and methods for controlling heat for rapid thermal processing of carbonaceous material are provided herein. The apparatus comprises a reheater for containing a fluidized bubbling bed comprising an oxygen-containing gas, inorganic heat carrier particles, and char and for burning the char into ash to form heated inorganic particles. An inorganic particle cooler is in fluid communication with the reheater to receive a first portion of the heated inorganic particles. The inorganic particle cooler is configured to receive a cooling medium for indirect heat exchange with the first portion of the heated inorganic particles to form first partially-cooled heated inorganic particles that are fluidly communicated to the reheater and combined with a second portion of the heated inorganic particles to form second partially-cooled heated inorganic particles. A reactor is in fluid communication with the reheater to receive the second partially-cooled heated inorganic particles.

A biochar kiln is disclosed. An example of the biochar kiln includes a body having a one-piece rolled wall, a curved floor attached to the sidewall by a single weld line, and a removable lid. The example biochar kiln includes a plurality of semi-independent combustion cells. The example biochar kiln also includes a ventilation subsystem, an ember suppression subsystem, and a stack subsystem. A control subsystem may configured to monitor a plurality of zones of the biochar kiln for a plurality of process control variables, to produce a quality biochar product with well-managed emissions.

A portable biochar kiln and system is disclosed. An example of a portable biochar kiln system includes a kiln body. A ridge is provided around an outside perimeter of the kiln body. A removable lid is provided to cover and uncover an opening in the top of the kiln body. An edge is provided around an outside perimeter of the removable lid. The example portable biochar kiln system also includes a gripper attachment for heavy machinery. The gripper attachment is configured for engagement with the ridge to raise and lower the kiln body. The gripper attachment is also configured for engagement with the edge of the lid to cover and uncover the kiln body.

The present invention provides a biomass combustion burner applied to a pulverized coal-fired boiler to burn biomass fuel, a biomass-mixed fired boiler that reduces an amount of CO2 derived from fossil fuels, and a method for burning biomass fuel using the foregoing. The biomass combustion burner includes a biomass fuel jet nozzle having a fuel jet port that jets biomass fuel conveyed by primary air; a secondary air nozzle having a secondary air jet port that surrounds the fuel jet port; and a tertiary air nozzle having a tertiary air jet port that surrounds the secondary air jet port. The biomass fuel jet nozzle includes a fuel concentration adjusting section that changes a biomass fuel stream into a swirl flow to thereby make a fuel concentration higher on an outer circumferential portion side; and a degree-of-swirl adjusting plate that reduces a degree of swirl of a jetting fuel stream.

A washing treatment system includes an odor and flue gas washing tower, a biological deodorization filtering tower, a multifunctional biomass combustion boiler, a liquid fermentation reactor, a solid fermentation reactor, circulating pumps, an exhaust fan and an induced draft fan. An exhaust port is formed in a top end cover of the odor and flue gas washing tower. A liquid inlet, an air inlet and a liquid drainage port are formed in a side wall of a tank body. A hanging basket is placed in the tank body. Organic fillers and/or inorganic fillers are placed in the hanging basket. An inner cavity of the washing tower is divided into a liquid inlet shunting cavity, a filler layer, an air cavity and a liquid accumulation cavity from top to bottom. An upper supernatant in the liquid fermentation reactor is connected with the liquid inlet for washing.

A microprocessor-based controller manages combustion within a biofuel furnace. A clinker agitator controller generates signals for controlling operation of a motorized clinker agitator of the biofuel furnace. The microprocessor-based controller may additionally control any of fuel feed rate, air supply rate and ash removal rate.

Provided is a biomass pyrolysis apparatus comprising: a combustion furnace that produces a heat quantity by causing a stable property fuel to combust; a pyrolysis gasification furnace that produces a torrefied material, and a pyrolysis gas by pyrolyzing woody biomass by a heat quantity produced by the combustion furnace; and a pyrolysis gas introduction passage that introduces the pyrolysis gas from the pyrolysis gasification furnace into a boiler, into which the torrefied material is introduced.

A combustion chamber has an internally hollow tank containing biomass to be combusted and gasified, an air supply to supply air inside the tank, a gas supply connected to a gas source to supply gas inside the tank, and valve or valves electrically connected to the control to control the air flow and the gas flow inside the tank.
