FIXED BED GASIFIER FOR PRODUCING A PRODUCT GAS FROM POURABLE CARBONACEOUS PARTICLES
20220403265 · 2022-12-22 ·

A fixed bed gasifier has a clinker breakup device. The tapping element of the clinker breakup device can be positioned at different points, allowing the tapping element to be small but capable of reaching all regions of the fuel particle bed. The tapping element intermittently enters the fuel particle bed in gasifying operation. Before it re-enters the bed, the drive mechanism adjusts the position of the tapping element so that it does not enter the same tapping channel again. Repeated local spiking at different times and locations moves the gasifier bed and disrupts the sintering of clinker particles that can block the gasifier cross section. Gas continues to flow through individual zones over the entire cross section, and not just in the tapped channel. Lumps of clinker that have sintered together are conveyed onward—toward the support device—or else broken up.

BIOPOWERPLANT: THIRD GENERATION BIOREFINERY WITH IMPROVED CAPACITY TO USE DOMESTIC WASTEWATER, LANDFILL LEACHATE AND SEA SALT WATER AS AN INPUT TO GENERATE GREEN ENERGY, WATER FOR REUSE, BIOFUEL, ORGANIC FERTILIZERS AND CAPTURE ATMOSPHERIC CO2
20230045512 · 2023-02-09 ·

The Biopowerplant is a system that integrates the generation of carbon-neutral energy through the cultivation and conversion of microalgal biomass, with sewage sanitation and environmental carbon recovery, with the additional and secondary production of biofertilizer, biofuel, water for reuse. This system integrates a suboptimal anaerobic digestion subsystem focused on the generation of biogas, the processing of the resulting digestate through a microalgal consortium culture subsystem with biofilm induction and smooth decreasing gradient of light radiation, and the transformation of the generated microalgal biomass into syngas through a subsystem of evaporation, torrefaction, pyrolysis, gasification, and combustion in separate chambers. The syngas and methane from the biogas are subsequently used as fuel in an electric power generator capable of operating with mixed gases. The biogas generation process is enriched through the recirculation of the microalgal biomass supernatant, the residual heat from the syngas generation subsystem, and the heat transferred from the combustion gases of the electric generator. The residual sludge from the biogas generation subsystem is recirculated towards a longitudinal biopile subsystem, where it acts as an anaerobic medium compared to the aerobic medium that constitutes the concentrated microalgal biomass, and both streams are mixed to be transformed into the syngas generation subsystem. Input inflows for system operation are mainly sewage, and optionally seawater and/or leachate. The inflows must be bioaugmented with a microalgal consortium dosed automatically by a Compact in situ bioaugmentation system, preferably more than 3 kilometers before the inflow enters the system.

20170349847 · 2017-12-07 ·

The present invention includes a gasifier for gasifying fuels having a container with a top, sidewalls and a bottom for facilitating the gasifying process. One or more open vertical shafts extend downward inside the container for allowing a downdraft or updraft of air and fuel for the gasifying process. A rotating bed is preferably included inside the container and below the one or more shafts for receiving the fuel. The bed rotates essentially perpendicular to the shaft to facilitate even heating and gasifying of the fuel. The bed is further movable relative to the vertical shaft in order to increase or decrease the volume of fuel flow to the fuel.
