Abstract Experimental studies have been carried out on the combustion of natural gas hydrate at different rates of oxidant U (air) in the laminar flow regime and at a fixed channel height. It is established that the dissociation rate J is related to the velocity U in a non-linear manner. With an increase in rate from 0 to 0.6 m/s, the dissociation rate increases and reaches a maximum. With a further increase in rate, J decreases. The dissociation rate does not depend on the initial concentration of methane in the sample. Experimental dependences of the effect of U on the dissociation rate of a natural hydrate in a channel have been obtained for the first time. The conducted studies are important for further development of natural hydrate combustion technologies.
