TRIFLUID REACTOR
First Claim
1. A reactor for reacting at least a first fluid comprising a first reactant and a second fluid comprising a second reactant, and mixing a diluent fluid with one or more portions of first fluid, second fluid and products of their reaction to form a reaction product, the reactor comprising:
- a duct having an axial direction and a first and second transverse directions mutually distinct from the axial direction, the first and second transverse directions defining a plane through an axial location, with the area of the plane within the inner surface of the duct defining a cross-sectional area of the duct at the axial location;
a reactant distribution portion comprising at least one reactant tubular portion having an inner surface and an outer surface, the inner surface defining a first flow path for the first fluid, and having a plurality of reactant distribution orifices extending from the inner surface to the outer surface, the plurality of reactant distribution orifices having a density distribution being the locally averaged spatial density of orifices per duct cross-sectional area, and having a size distribution, the distributions being with respect to at least one of the transverse directions;
a diluent distribution portion comprising at least one diluent tubular portion having an inner surface and an outer surface, the inner surface defining a first diluent flow path for the diluent, and a plurality of diluent orifices extending from the inner surface to the outer surface of the diluent tubular portion, the plurality of diluent orifices having a density and a size distribution, the distributions being with respect to at least one of the transverse directions;
a reactant delivery system for supplying the first fluid to the reactant distribution portion;
a second fluid delivery system for supplying at least a portion of the second fluid to the duct, wherein the duct defines a second flow path for the second fluid;
a diluent delivery system for supplying at least a portion of diluent to the diluent distribution portion;
a controller for controlling the delivery of the first fluid, the second fluid and the diluent fluid to the reactor; and
wherein the density and size distribution, with respect to at least one of the transverse directions, of the diluent orifices and of the reactant orifices are configured such that the distribution of at least one of the composition, temperature, pressure and velocity of the reaction product, is controlled in the at least one transverse direction in a cross section of the duct near the reactor exit, taken along a direction transverse to the duct axis.

Abstract
A thermally diluted exothermic reactor system is comprised of numerous orifices distributed within a combustor by distributed perforated contactor tubes or ducts. The perforated contactors deliver and mix diluent fluid and one or more reactant fluids with an oxidant fluid. Numerous micro-jets about the perforated tubes deliver, mix and control the composition of reactant fluid, oxidant fluid and diluent fluid. The reactor controls one or more of composition profiles, composition ratio profiles and temperature profiles in one or more of the axial direction and one or two transverse directions, reduces temperature gradients and improves power, efficiency and emissions.
