PULSE-DETONATION STEAM SUPERHEATER

Abstract

In [1], we patented the innovative pulse-detonation steam superheater (PDSS) for deep oxygen-free and pollutant-free gasification of organic municipal and industrial wastes to produce a gas mixture of H2 and CO. The PDSS is essentially the pulse-detonation engine operating on the ternary fuel-oxygen-steam mixture with fuel represented, e. g., by a gas mixture of H2 and CO (energy gas or syngas). The low-temperature steam (375-380 K) is produced by a standard steam generator. Pulsed detonations in the PDSS are achieved due to intermittent spark ignition of the fuel-oxygen mixture followed by fast deflagration-to-detonation transition and transmission of the detonation wave to the ternary fuel-oxygen-steam mixture. It is implied that the PDSS is directly connected to the waste gasification flow reactor and normally operates on the H2-CO energy gas. However, for starting the plant, the PDSS initially operates on any available hydrocarbon fuel or hydrogen.
