Abstract (en)

Gasogen to produce combustion gases for external combustion in boilers, furnaces internal combustion engines and other devices or apparatuses which use said gases, being the gasogen of the fixed upstream type with refrigerated walls where the biomass or material to be gasified is subjected to a series of processes such as drying, pyrolysis, reduction of the carbon dioxide generated into carbon monoxide and burning of the residual carbon. The walls of the gasogen arc composed of a number of cooling pipes with heat dissipation membranes, the gasogen includes an exocentric rotating grid for the extraction of ashes, at least one peripheral and one central blower with the corresponding sets of steam and/or inert gases injection nozzles to ease the extraction of ashes, at least one gas exhaust gate which blocks the pipe connected to the combustion chamber and an ancillary funnel with an exhaust valve for the paralyses gases. The treatment of the biomass is improved adding selected compounds between calcium hydroxide, calcium carbonate and/or double calcium and magnesium carbonate in variable proportions according to the type of fuel that enters the gasogen
