A process and apparatus for densification of material compresses the material, then heats and cools the compressed material to provide structural integrity and durability to the resultant densified product. For a lignocellulosic biomass material an inherent binder is used. The binder is activated substantially only along the periphery of the compressed material to increase throughput and reduce energy used during the densification process. To optimize throughput and densified material density and durability, the process and apparatus includes a compaction pressure measurement that provides a signal to a constrictor located at the exit, or between the exit and initial compaction location, to automatically control compaction pressure as material type, initial density, moisture and load weight vary.

The invention provides systems and methods for electric power production and integrated combustion and emissions control. The invention may include an engine capable of receiving air and fuel, and producing power and an engine exhaust gas. The invention may also include a first reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of more than one, thereby generating a first product. The combustion may reduce nitrogen containing species. The invention may also include a second reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of less than one, thereby generating a second product. The combustion may reduce or minimize NOx. The invention may also include a mixing zone configured to receive the first product and second product, and mix and react the first and second products, thereby generating an exhaust with reduced NOx levels. This may occur with sufficient residence time and temperature to complete combustion and promote nitrogenous species reduction reactions. For inventions with multiple zones, fuel or air or exhaust gas may be adjusted, diverted or turned off as load is reduced to maintain flame stability for all zones that remaining operational. For inventions with engine exhaust that provides less oxidant than the burner requires, an air eductor means may be arranged between the engine and the burner that entrains needed additional oxidant and simultaneously recovers the flow energy in the turbine exhaust.

Non-isotropic structures for heat exchangers and reactors
A Non-Isotropic Structure for a Heat Exchanger (NISHEX) that forms fins from nested woven wire meshes. The wire meshes are shaped into channels that are stacked on top of each other to produce a non-isotropic fin structure having multiple fin layers. The fin structure exhibits a high heat coefficient while maintaining relatively high fin efficiency through the selection of fin lengths in proportion to the wire diameter in the mesh fins.
