Internal combustion and waste heat steam engine having a heat recovery steam generator exhaust manifold

摘要

An improved internal combustion and waste hat steam engine having an heat recovery steam generator optimized for the steam cycle, that can operate on steam, fuel, or a water-fuel composition where the mixture is at a critical temperature and in a homogeneous single phase. The condensing waste heat recovery steam generator exhaust manifold is close-coupled to the engine cylinder exhaust ports and provides heat to create the homogeneous mixture and steam. The primary heat source is internal combustion. An external heat source may be coupled with the engine to increase the heat available to the condensing waste water recovery steam generator exhaust manifold to produce additional steam. The engine can be operated as a pure diesel engine, for warm-up or for when an external source of steam is desired.
