Abstract:

A radial flow steam injection heater that injects a selected amount of steam into a product flow to heat the product flow. The steam injection heater includes a mixing tube that receives the product flow to be heated. The mixing tube includes a series of steam injection holes that are positioned within a steam chamber defined by the heater body. Pressurized steam within the steam chamber flows into the mixing tube in a direction transverse to the flow axis through the steam injection holes. A regulating member is selectively movable relative to the mixing tube to expose the steam injection holes to the steam chamber to control the amount of steam utilized to heat the product flow.
