Abstract
Heated oven inlet gases enter a receiving chamber within the oven and are disbursed into the oven interior through directionally oriented, venturi-like outlets. Interior oven gases are allowed to be drawn into the resulting low pressure zones so as to mix with the inlet gases and inducing a circulation pattern within the oven interior.
Claims7
Atmosphere distribution apparatus comprising;
- an oven having a plurality of walls, a gaseous atmosphere filled interior, an inlet and an outlet;
- means for providing a flow of heated input gases into said inlet;
- an inlet chamber for receiving said input gases into said oven, said input gases being received at a first velocity;
- means for guiding the flow of said input gases from said inlet chamber into the interior of said oven;
- said guiding means further comprising means for locally increasing the velocity of said flow of input gases to a second, higher velocity so as to create a low pressure zone;
- and
- means for directing oven interior gases into said low pressure zone so as to induce a pattern of mixing and recirculation in said gaseous atmosphere filled interior.

Oven atmosphere distribution apparatus comprising;
- an oven having a plurality of walls, a gaseous atmosphere filled interior, an inlet and an outlet;
- means for providing a flow of heated input gases into said inlet;
- a cover plate forming an inlet chamber within said interior, said chamber being positioned to receive said flow of input gases, said input gases being received at a first velocity;
- a plurality of directional outlets from said inlet chamber to pass said flow of input gases from said inlet chamber into the interior of said oven;
- at least one said directional outlet including a converging cross-section so as to increase the velocity of said flow of input gases to a second, higher velocity and create at least one low pressure zone;
- and
- an aperture in said cover plate, adjacent said at least one said directional outlet and admitting oven interior gases into said at least one low pressure zone so as to induce a circulation pattern in said gaseous atmosphere filled interior.
4 more elements
A method of for distribution of oven interior gases comprising;
- providing an oven having an inlet, an interior and an exhaust;
- providing a flow of heated gases input into said oven through said oven inlet;
- providing an inlet chamber within the oven interior for receiving gases input to said oven;
- providing a plurality of directional outlets from said inlet chamber, each said outlet including a converging cross-section;
- flowing said input gasses through said plurality of converging cross-section directional outlets, into the interior of said oven, so as to create a plurality of low pressure zones;
- and
- admitting oven interior gases into said low pressure zones so as to induce a circulation pattern in said gaseous atmosphere filled interior.
