Abstract
Abstract A cooler for the passage of a regulable partial current of heat carrier in a reaction vessel includes a cooler housing having longitudinally spaced inlet and outlet connections. A plurality of cooling tubes extend longitudinally through the housing and the interior of the housing is divided into a flow path along and around the tubes from the inlet to the outlet and a control flow through a by-pass extending from the inlet to the outlet on the exterior of the tubes but within the housing. The coolant is circulated through a central coolant inlet tube which extends centrally within the tube bundle for flow from the chamber defined at the far end upwardly through the tubes to an opposite chamber for removal. The by-pass flow is regulated by means of a slide valve which may be slid along the by-pass passage to divert a portion of the inlet flow through the inlet so that it flows directly through the by-pass to the outlet and is not affected by the cooling tubes. The circulation to the cooler may be from the interior of the reactor to the inlet and from the outlet back into the reactor. Alternatively, the flow may be through an annular conduit extending around the reactor from the outlet of the cooler and thence downwardly on the exterior passage around the annular outlet back to the inlet. The first partial current conducted around the cooling tubes and the second partial current conducted through the by-pass passage, which are regulable relative to each other, form together a constant partial current of the heat carrier circulated in the reaction vessel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A cooler for a heat carrier comprising an elongated housing having an inlet connection secured thereto fo introducing the heat carrier into said housing and an outlet connection secured thereto and spaced in the elongated direction of said housing from said inlet for withdrawing the heat carrier from said housing after its flow therethrough, a nest of tubes positioned within and spaced inwardly from said housing and said nest of tubes extending between said inlet and said outlet, means within said housing for defining a first passage for the flow of the heat carrier over said tubes and for defining a second passage for bypassing the flow of the heat carrier about said tubes within said housing, said first and second passages each being in communication at one end with said inlet and at the other end with said outlet, and movably positionable flow control means located within said housing at said inlet for selectively dividing the flow of the heat carrier introduced through said inlet into said first and second passages for regulating the flow of the heat carrier over said tubes.
Claim 2
Dependent Claim
183 words
A cooler for a heat carrier comprising an elongated housing having an inlet connection secured thereto fo introducing the heat carrier into said housing and an outlet connection secured thereto and spaced in the elongated direction of said housing from said inlet for withdrawing the heat carrier from said housing after its flow therethrough, a nest of tubes positioned within and spaced inwardly from said housing and said nest of tubes extending between said inlet and said outlet, means within said housing for defining a first passage for the flow of the heat carrier over said tubes and for defining a second passage for bypassing the flow of the heat carrier about said tubes within said housing, said first and second passages each being in communication at one end with said inlet and at the other end with said outlet, and movably positionable flow control means located within said housing at said inlet for selectively dividing the flow of the heat carrier introduced through said inlet into said first and second passages for regulating the flow of the heat carrier over said tubes.
