Experimental study of dissociation of double gas hydrate at various combustion methods

Abstract

The dissociation during combustion of a propane-methane gas hydrate double powder is experimentally investigated. Gas hydrate combustion is implemented in four ways: 1) induction heating; 2) radiation and convective heating in a muffle furnace; 3) combustion without forced gas flow; and 4) combustion in the presence of forced air convection u a. The maximum J is achieved by burning granules of gas hydrate powder on a metal surface with induction heating, where J is the specific dissociation rate. The minimum of J corresponds to the combustion of a layer of gas hydrate powder in the absence of forced air flow. With an increase in the velocity air convection u a from 0 to 1.2 m/s the J increases and reaches a maximum. A further increase in u a leads to a decrease in J. For u a > 3.5 m/s combustion does not occur.
