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.

A method and apparatus for thermal processing of contaminated liquids is disclosed. The system employs an efficient and robust pulse jet burner as its basic energy source. This energy is then used to generate steam which may subsequently be used for a variety of processing and purification steps. A multiple-chamber approach is used: a burner chamber contains the pulse jet burner, a neighboring heat exchanger chamber uses this heat energy to initiate the purification process which started in a third neighboring coagulator chamber into which the contaminated fluids are initially introduced to the system. Combustible liquids which are separated from the contaminated fluids may be used to power the pulse jet for self-contained operation. High temperature flue gases from the pulse jet pass through a supercharger box and then into a vortex dryer which may have a secondary vortex dryer for initial drying of wet solid fuels.

To provide a pyrolysis apparatus capable of pyrolyzing an object to be treated without releasing exhaust gas to the atmosphere. This pyrolysis apparatus includes: a treatment furnace having a pyrolysis section where an object to be treated is subjected to pyrolysis on a grate; a purification water tank retaining water and having a gas pool formed in an upper part thereof; a primary purification tank connected to the upper part of the purification water tank, in which water is jetted toward exhaust gas flowing in from an upper part of the treatment furnace through a gas flue; a piping through which gas is taken up from the gas pool of the purification water tank and returned to the primary purification tank; a secondary purification tank connected to the upper part of the purification water tank, in which water is jetted toward the gas taken up from the gas pool of the purification water tank; and a return piping through which the gas having passed the secondary purification tank is fed into the treatment furnace.

A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. 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 material is pulverized to a particle size of less than about 2 mm. 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 nitrogenous hydrocarbon combustion reactions within the combustion chamber are also controlled by injection of steam within the combustion chamber.
