Abstract: Reactor for production of furnace soot contg. along the reactor axis a combustion chamber, a mixing chamber and a reaction chamber linked together forming in that order a flow path for the hot combustion gases. The mixing chamber forms an axial narrow section in a partition wall separating the combustion chamber from the reaction chamber. Upstream of the mixing chamber, the combustion chamber has inlet openings for feeding an oxygen contg. gas and a combustion device, as well as one or more spray or injection nozzles for soot raw material in the mixing chamber. In the reaction chamber downstream of the mixing chamber there is at least one quenching nozzle for water to quench the soot forming reaction. Additionally, the combustion and reaction chambers are linked together by at least one outer axially arranged shunt hole in the partition wall. Also claimed is a process to produce soot using the above reactor in which the gases are divided into a central flow and side flows before the mixing chamber. The central flow is fed through the mixing chamber and the side flows are fed to the periphery of the central stream after its expansion in the reaction chamber.

Abstract: A nest of heat exchanger tubes is introduced for heating a gas which is at a low temperature by means of a gas at a high temperature to variable temperatures ranging from the maximum for which the installation is designed to a lower value, using a given quantitative ratio of the two gases, which heat exchanger has at least one additional intake pipe connection for the low temperature gas situated in the lower region of the housing, between the intake pipe connection and discharge pipe connection for the gas to be heated, near the inflow of heating gas, and connected with a device for measuring the quantities. The system is particularly useful for producing different types of carbon black.
