Household refuse tip degradation accelerated by through flow of pure oxygen from lance array

摘要

In a process and assembly to condition a heaped deposit of household refuse (1), pure oxygen (4) is continually pumped (4) through lance pipes (2) inserted at the base of the heap. The oxygen is pumped at a pressure of between 1.5 and 4 bar through lance pipes of between 25 and 35 mm diameter, inserted at intervals of 2 to 5 meters to a distance within the heap of 1 to 2 meters.
