A multi-fueled impulse initiator that includes a fuel source equipped with a control valve, an air source equipped with a control valve, a removable air flow insert having opposing inlet and outlet faces, an air expansion chamber fluidly connected to both the air source and the inlet face of the removable air flow insert, and an igniter assembly having a sparking tip. The removable air flow insert includes channels traversing from the inlet face to the outlet face of the air flow insert.

In the case of mono sewage sludge incineration, a solution may be created that enables sewage sludge ash, which may still have a low proportion of unburned carbon, to be discharged from a mono sewage sludge incineration plant. This is achieved by a method for the post-combustion of sewage sludge ash obtained in a mono sewage sludge incineration in a rotary kiln by means of a hot and a low oxygen content, such as an oxygen content of 5-10 vol. % oxygen. The gas stream from the rotary kiln may escape the sewage sludge ash and is fed to the gas flow. This sufficiently hot gas flow may cause oxidation or afterburning of unburned carbon contained in the sewage sludge ash.

Systems and processes provide for a thermal process to transform sludge (and a variety of other natural waste materials) into electricity. Dewatered sludge and other materials containing a high amount of latent energy are dried into a powdered biofuel using a drying gas produced in the system. The drying gas is recirculated and is heated by the biofuel produced in the system, waste heat (from turbines or internal combustion engines), gas (including natural gas or digester gas) and/or oil. The biofuel is combusted in a boiler system that utilizes a burner operable to burn biofuel and produce heat utilized in a series of heat exchangers that heat the recirculating drying air and steam that powers the turbines for electricity production.

Cogeneration plant for the continuous production of electrical and thermal energy from solid woody biomass, the latter being selected from among wood in the form of woodchips, vine branches, shrubs and underbrush, grain, hay, animal litter, suitably-treated muds, shells and kernels, suitably-treated husks, fibrous cultures and compositions thereof, the plant including at least one first container and at least one second container connected by at least one interconnection duct, the first container including the components suitable for inducing the transformation of the biomass into syngas including H.sub.2 and CO; the plant providing for a particular step of screening, drying and briquette-making on board the machine of the solid woody starting biomass.

An apparatus and a method are provided for continuously drying bulk goods, in particular wood fibers and/or wood chips, in a dryer, wherein the drying vapors are led to a dryer circuit, in which the drying vapors are indirectly heated via a heat-exchanger and are conducted to the dryer again.

Aspects of the present disclosure include devices, systems, methods, and control systems for processing waste into usable products, such as fuel stock, soil additives, and usable byproducts. Various system components may include: 1) a material loading area; 2) a pre-shredder; 3) a magnet based separator; 4) an eddy current separator; 5) additional sorting devices, such as a ballistic separator and/or an optical separator; 6) a mechanical pulverizer, such as a vertical shaft impactor (VSI); 7) a moisture separation device, such as a cyclone; 8) a compressor, such as a ram baler; 9) a packager, such as a bale wrapper; 10) analyzers, such as for moisture and caloric data analysis; 11) a thermal pressure chamber, such as a thermal screw; and 12) a control system to control operation of the system.

A municipal solid waste recycling facility for producing a solid recovered fuel is provided. The municipal solid waste recycling facility includes a pre-shredding unit and a shredding unit. The pre-shredding unit includes a trommel configured to sort a first stream of solid waste by size into a second stream of solid waste and a third stream of solid waste. The shredding unit includes a primary shredder configured to shred the second stream of solid waste.

The invention provides for the integration of a gas fermentation process with a gasification process whereby effluent downstream from the gas fermentation process is recycled to the gasification process. The invention is capable of recycling one or more effluents including biogas generated from a wastewater treatment process, tail-gas generated from the fermentation process, unused syngas generated by the gasification process, microbial biomass generated from the fermentation process, microbial biomass generated from a wastewater treatment process, crude ethanol from the product recovery process, fusel oil from the product recovery process, microbial biomass depleted water, wastewater generated from the fermentation process, and clarified water from a wastewater treatment process to a gasification process.

The system for processing waste includes both a fixed bed reactor and a fluidized bed reactor. The fixed bed reactor receives a first waste material and produces a first set of reaction products. The fluidized bed reactor is adapted for receiving a second waste material and producing a second set of reaction products. The first and second sets of reaction products may be selectively and adjustably mixed to produce a mixed set of reaction products. At least one cyclone separator receives the reaction products and separates and collects solids (waxes) from the product stream. At least one condenser receives the product stream and removes a condensable liquids from the product stream. The condensable liquids are collected, and a gas-liquid separator removes any remaining liquid from the gas stream. The remaining gas is then output as gaseous product.

Complex of equipment for a waste-free processing of biodegradable municipal waste is solved in such a way that at the input (1) of BMW a crusher (2) is included, the output of with is connected to either a hygieniser (3) or a drying line (5). The output from the hygieniser (3) is connected to the biogas plant (4) input. The output of the bulk intermediate from the biogas plant (4) is connected to the drying line (5). The drying line (5) output is connected either to a pyrolyzer (7) with a second product output (7.1) of bio-coal or is connected to a compaction machine (8). The drying line (5) or the compaction machine (8) has the first product output (8.1) of soil substrate. From the pyrolyzer (7) to the drying line (5) there is a return loop included through a mixing device (6) with input (10) of bio-nutrient waste, whereby the compaction machine (8) included after the drying line (5) has a third product output (8.2).
