This research is a part of the investigation on the pneumatic spreader stoker, which conveys the slacks with air (or steam) through the conveying pipe to the nozzle, and spreads them on a fire grate. In this paper, we theoretically analised the accelerating state in a horizontal pipe and the flying distance on a fire grate of a particle, on the following assumptions. 1. The frictional force acting on a particle in a horizontal pipe, increases exponentially with time. 2. The jet stream does not diffuse, and the width of jet stream remains constant. as nozzleexit. 3. A particle is horizontally injected at nozzle-exit. Next, we studied them experimentally for several kinds of particles, and compared the theoretical results with experimental ones.
