Experimental and analytical studies of the processes of decay during spontaneous combustion of vegetable raw materials

Abstract

Is characterized by a hidden focus and slow spread in an environment with finely dispersed combustible substances and materials. In this paper, a review of studies of the processes of decay during spontaneous combustion of vegetable raw materials is carried out, the results of experimental studies of the processes of decay of this product are presented. The process of plant materials has a heterogeneous character, therefore, the size and nature of the surface of the solid phase in the form of a fine – dispersed material with a developed surface play an important role in it. Thermal, chemical and microbiological processes, as well as smoldering during spontaneous combustion, can serve as an impulse for heating and igniting plant materials. The causes of the occurrence and conditions of the processes of the origin and formation of foci of decay in materials of plant origin in large – volume storage facilities are experimentally investigated. The features of processes suppression of materials of plant origin in silo – type warehouses are considered.
