Methane gas generator provided with cavity wall structure

摘要

A biogas (methane and carbon dioxide) generator has a housing (2) with an inner wall (8) with a gap to an internal reactor vessel (3) and inner heater with an inlet (4) for pre-acidified organic material (4) and discharge unit (5) for spent organic material. The outer face (7) of the reactor vessel (3) and the inner wall (8) of the housing (2) are separated by a panel (9). The discharge (5) unit draws the gas-generating organic material from one side of the panel (9) into the gap (6) between the outer face (7) and inner wall (8). Spent organic material is discharged through a housing (2) outlet (10) near to the other side of the panel (9).
