Реферат: ABSTRACT OF THE DISCLOSURE An air blower is used with an incineration pit dug below ground level. The blower includes a motor and a fan driven by the motor. A plenum chamber receives air from the fan and has a cross-sectional shape of at least three sides including a flat base flush with the ground level and a front side sloping away from the pit. Preferably, the plenum chamber has a trapezoidal cross-section. A nozzle connected to the plenum chamber jets an air curtain over the open fire in the pit. A protective fence attachable to the plenum chamber surrounds the pit. Also, there may be one or more telescoping sections slidable out of either one or both opposite ends of the plenum chamber for jetting additional air curtains over the open fire in the pit.
