Aqueous additives in hydrocarbonaceous fuel combustion systems

摘要

An aqueous additive containing a metal compound is used to improve the operation of combustion exhaust after treatment systems. The additive is introduced into the combustion chamber as part of an emulsion with the fuel or, alternatively, in the emulsion or alone as an aqueous stream introduced into the exhaust or emission path. The metal compound scavenges combustion byproducts in order to protect and make more efficient the after treatment system.
