A cryogenic freezer is disclosed for embrittling scrap material, such as random size pieces of automobile tires, prior to fragmentation of the embrittled scrap material in an impact mill. The freezer includes a product discharge gas lock which is designed to minimize the loss of cryogenic refrigerant while, at the same time, accomodating unusually large pieces of scrap material.

Cryogenic embrittlement freezer with gas lock

A burner for combusting hydrocarbon fluids which may contain additional components as additives or contaminants and in the form of a gas, liquid or particulate matter, e.g. waste oil wherein the oil is atomized in a nozzle disposed in a housing defining a combustion chamber for receiving an oxidizing fluid, e.g. oxygen, so that atomized oil is mixed with the oxidizing fluid for combustion. Control of the length to diameter (L/D) ratio of the combustion chamber results in lower operating noise levels for the burner during combustion.
