Abstract
An apparatus, system, and method for heating fluidic material includes a sleeve positioned within a housing, with at least a portion of at least one heating element passing through the sleeve and an annulus defined by an exterior surface of the sleeve and an interior surface of the housing. A flow restrictor is positioned within the housing to control the flow of fluidic material through the sleeve relative to the flow of fluidic material through the annulus, the fluidic material through the annulus having a higher linear velocity than the flow through the sleeve.

An apparatus for heating a fluid material, the apparatus comprising:
- a tubular housing defining a passageway therethrough and having an upstream end adapted to be operably coupled to an inlet stream of fluidic material and a downstream end having an outlet;
- a sleeve positioned concentrically within the passageway and defining an annulus between the sleeve and an inner diameter of the housing, the sleeve having a sleeve passage therethrough, the annulus and the sleeve passage each being in communication with the passageway so that when fluidic materials flow through the passageway, a portion of the fluidic material flows through the annulus and another portion of the fluidic materials flow through the sleeve passage;
- one or more heating elements positioned within the outer housing with at least a portion of each of the one or more heating elements positioned within at least a portion of the sleeve;
- and
- a flow restrictor positioned to restrict the flow of the fluidic material through the sleeve passage.
An apparatus for heating a fluidic material, the apparatus comprising:
- a tubular housing that defines a passageway, wherein an upstream end of the passageway is adapted to be operably coupled to an inlet stream of fluidic material and a downstream end of the passageway comprises an outlet;
- a sleeve positioned concentrically within the passageway and defining an annulus between the sleeve and an inner diameter of the housing, the sleeve having a sleeve passage therethrough, the annulus and the sleeve passage each being in communication with the passageway so that when fluidic materials flow through the passageway, a portion of the fluidic material flow through the annulus and another portion of the fluidic materials flow through the sleeve passage;
- one or more heating elements positioned within the outer housing so that at least a portion of each of the one or more heating elements extends through at least a portion of the sleeve passage;
- and
- a flow restrictor positioned to reduce the flow of fluidic materials through the sleeve passage so that the linear velocity of the fluidic materials in the annulus is greater than the linear velocity of the fluidic materials in the sleeve passage.
A method for heating fluidic material, the method comprising the steps of:
- (a) placing a sleeve inside a housing and creating an annulus therebetween;
- (b) positioning at least one heating element within the housing so that at least a portion of the heating element passes through the sleeve;
- and
- (c) flowing a fluidic material through the housing, a portion of the fluidic material flowing through the annulus and a portion of the fluidic material flowing through the sleeve, the portion of fluid flowing through the annulus having a higher linear velocity than the portion of fluid flowing through the sleeve.
