NOVELTY - An apparatus for continuous cycle thermochemical decomposition of biomass has reaction chamber (37) where biomass is conveyed to produce gas (G1), 1st pipe (35) to convey biomass into reaction chamber (37), 2nd pipe (45) connected to the upper part of reaction chamber (37), containing unit (53) to define an interstice (57) both around reaction chamber (37) and around 2nd pipe (45), 1st apertures (49) to enable connection between reaction chamber (37) and interstice (57), and 2nd apertures (51) to enable communication between 2nd pipe (45) and interstice (57), and to generate a flame cap.    USE - Apparatus for continuous cycle thermochemical decomposition of biomass (claimed).    ADVANTAGE - The apparatus produces heat energy with high yield and low emission of particulate of carbon monoxide and carbon dioxide.    DETAILED DESCRIPTION - An apparatus for continuous cycle thermochemical decomposition of biomass has reaction chamber (37) where biomass is continuously conveyed to produce gas (G1) by pyrolysis or gasification of biomass, with air (A) input from outside the reaction chamber (37), 1st pipe (35) provided along 1st axis (X) passing and connected through reaction chamber (37) to convey biomass into reaction chamber (37), 2nd pipe (45), provided along 2nd axis (Y), perpendicular to 1st axis (X), and connected to the upper part of reaction chamber (37), containing unit (53) provided outside the reaction chamber (37) to define an interstice (57) both around reaction chamber (37) and around a part of 2nd pipe (45), where air (A) is conveyed, 1st apertures (49) provided in the wall of reaction chamber (37) to enable connection between reaction chamber (37) and interstice (57), and 2nd apertures (51) provided in the wall of 2nd pipe (45) to enable communication between 2nd pipe (45) and interstice (57), and to generate a flame cap in 2nd pipe (45). An INDEPENDENT CLAIM is included for method for continuous cycle thermochemical decomposition of biomass.
