Mixing block for thermal deburring - with cyclone type mixing chamber for fuel gas and oxygen

摘要

The mixing block for the admission of a combustible gas mixt. into the treatment chamber, esp. of a plant for the thermal deburring of workpieces, has at least two inlets to a mixing chamber for the gas components and one outlet for the mixt. The latter is arranged axially to the mixing chamber and the gas inlet bores terminate tangentially in it. The cyclone action of the mixing chamber results in an intensive mixt. between fuel gas and oxygen. A conical outlet of the mixing chamber increases the flow velocity in the gas outlet bore.
