Sintering of Salt-affected Soils

A stationary soil-sintering device was used to determine optimal conditions of thickness of spread soil on the conveyor, and conveyor speed. When this soil thickness was 15 mm and the conveyor speed was 5.7 mm s-1, the maximum thermal efficiency (about 30%) was obtained. When these conditions were applied to a prototypical soil-sintering plough attached behind a tractor, the required plough travel speed was 1.9 mm s−1 (6.84ß10−3 km h−1) for practical use with 3 burners, 90 mm in the operating depth and 300 mm in the operating width.
