Verfahren und Vorrichtungen zur Vergasung kompaktierter organischer Materialien

摘要

Bales enter through the casing (1) and slide valves (3) forming an air lock in the fuel supply channel (2). Reaching the gasification chamber (4), they rest on the slag trough (9), burning in oxygen from concentrically-surrounding lances (5). Molten slag in the trough (9), is collected for further cooling by water and raw gas injection. In a process to gasify baled organic wastes, bales enter through the casing (1) and slide valves (3) forming an air lock in the fuel supply channel (2). Reaching the gasification chamber (4), they rest on the slag trough (9), burning in oxygen from concentrically-surrounding lances (5) supplying a majority of gasification oxygen required. Secondary air (6) is used in temperature control. A start-up ignition and pilot burner (7) is included. Molten slag in the cooling-jacketed trough (9), is collected for further cooling in the quench chamber (11) by water and raw gas injection. Cooled gas leaves via the outlet (12). Cooled and granulated slag is removed from the quench chamber by the extractor (13). An Independent claim is included for corresponding equipment carrying out the process. Preferred features: By cooling the molten slag, a thick, dense, solid slag layer is formed, protecting the cooling jacket from thermal stressing and corrosion. A variants based on the foregoing principles is also described.
