    摘要: Effluent from a carbon black reactor is directly discharged from the reactor to a quick cooling radiant heat exchanger before, or in some instances after, a reaction-stopping water quench. The cooled reaction quench is then supplied to an air preheater to preheat the carbonaceous feed stock that is supplied to the reactor. The heat exchanger includes a chamber having outside walls formed by heat exchanger tubes which are welded together. If desired, additional cooling capacity is provided by platens formed of heat exchanger tubes which are contained in the chamber to which the reactor effluent is supplied.

    摘要: A burner apparatus for reducing carbon production, comprises a burner having a combustion chamber (280) and a heat exchanger (288) located within the combustion chamber (280). The heat exchanger has an inlet end (296, 298) where a mixture comprising air and fuel enters, a heat transfer section (288a, 288b), and an outlet end (304) from which a process mixture of air and fuel discharges into the combustion chamber (280) and is ignited to produce a product mixture. The inlet end and outlet end are located such that the general flow direction of the air and fuel within at least a portion of the heat transfer section is substantially parallel with flow direction of the product mixture in the combustion chamber (280). The heat transfer section is located within the combustion chamber so as to receive thermal input from the combusted product mixture therein to heat the process mixture to a temperature sufficiently high to substantially reduce the production of solid carbon therein. The invention is also for a method of reducing carbon production.

    摘要: In order to thermally decompose gaseous initial substances, in particular toxic substances, shapphire is used as wall lining material for the reaction chamber. In a decomposition process, the initial substances (2) flow through a heated reaction chamber (6) and the composition of the reaction gas from the initial substances (2) and from the final products (8) is monitored by spectral analysis through the optically transparent walls of the reaction chamber, so that operation parameters such as temperature and throughflow speed may be controlled in order to decompose the initial substances in a substantially total manner. A high temperature furnace has sapphire pipes (6/1, 6/2, 6/3, 6/4) in which gaseous initial substances are thermally decomposed at temperatures from 1200 DEG C to 2000 DEG C. Optical measurement devices (9/1, 9/2, 9/3, 9/4) are provided for monitoring the composition of the reaction gas.
