Assignee:

Gaumer Company, Inc. - Houston TX

International Classification:

H05B 3/44

US Classification:

219544, 219618, 219624, 219628, 219629, 219630, 219 591, 219 67, 219236, 219243, 219437, 219523, 219534, 219535, 219541, 219542

Abstract:

An electrical heater bundle has heater elements, each including a metal tube, an electrical resistance coil within the tube, a conductor pin connected to the coil and protruding from an end of the tube, and an electrical insulation powder surrounding the coil within the tube. A conical cavity is located in the insulation powder at the end of the tube, the cavity extending from an inner diameter of the tube to the conductor pin. The cavity is filled with an epoxy that is cured in place. The insulation powder may have an infiltrated layer at the cavity that is an uncured liquid silicone. The heater elements are mounted to a header plate, and the elements associated with the three different phases of electrical power may protrude past the header plate at different distances.

Abstract:

An electrical resistance heater element has a metal tube containing an electrical resistance coil that is electrically insulated from the metal tube by magnesium oxide powder, the coil being bonded to a conductor pin that protrudes from an open end of the tube. The powder is sealed against moisture by placing at least the open end of the tube within a chamber and immersing the open end within liquid silicone. A gas is pumped into the chamber to pressurize the silicone sufficiently to cause some of it to encroach into the powder through the open end of the tube. The heater element is installed within a heat exchanger with the silicone remaining uncured.

International Classification:

B01D 46/00

US Classification:

553851, 554181, 554901, 219438, 392485

Abstract:

A feed gas conditioner includes a pressure vessel that encloses at least part of a pre-heater. The pre-heater has an inlet for connection to a source of feed gas and an outlet for delivering the feed gas into the interior of the pressure vessel. An electrical heater element located within the pre-heater increases the temperature of the feed gas as it flows through the pre-heater. An expansion valve reduces the pressure of the feed gas as it flows from the pre-heater so as to initiate condensation. A super heater is at least partially located within the pressure vessel and has an inlet within the interior of the pressure vessel. A filter is in a flow path in the pressure vessel leading from the pre-heater heater to the super heater for removing condensate from the feed gas. An electrical heater element is in the super heater for heating the feed gas.

US Classification:

392491, 138 37, 138 38, 138 40, 138 42, 1651091

Abstract:

A feed gas conditioner includes a passageway with a plurality of heating elements positioned within the passageway. A plurality of baffle assemblies can cause a fluid flowing through the feed gas conditioner to flow in a serpentine flow pattern so that the fluid flows transverse to at least a portion of the heating elements. The baffle assemblies can each include two or more baffle elements, the baffle elements being positioned at an angle relative to each other. The heating elements can pass through passages within one or more of the baffle elements.
