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.
