Definitions

  • the present invention relates to the use of burners with a radiant tube for heating a reactor for the reaction of chlorosilanes.
  • heated chemical reactors e.g. Tubular reactors that are heated electrically or by burners using liquid or gaseous fuels.
  • the burners act directly in the space of the reactor, in which the facilities for harboring the chemical substances of the reaction, eg. B. pipe arrangements are housed.
  • the invention accordingly provides for the use of a burner for heating a reactor for reacting chlorosilanes, the burner having a jet pipe, and the jet pipe surrounding the flame and the flame tube in a gastight manner, whereby the combustion air, the gaseous and / or liquid fuel, and flue gases not in the room of
  • Reaction furnace can get.
  • burner with jet pipe In the context of the invention, the described arrangement of the burner is referred to as "burner with jet pipe".
  • the use of burners with jet pipe according to the invention has the advantage, above all, of facilitating the reliable conversion of chlorosilanes, since in reaction furnaces in the reaction with chlorosilanes, for example in the hydrogenation of chlorosilanes, the contact of flue gases with the reaction gas must be avoided at all costs, if that
  • Reaction medium exits through a defect of the harboring arrangement in the furnace chamber. In a contact of the moisture of the flue gas with chlorosilanes otherwise undesirable, violently exothermic reactions would occur.
  • Reaction media is introduced. This prevents local overheating of internals of the reaction furnace by avoiding direct contact with the burner flame. The heating is also very even.
  • the arrangement of the burner according to the invention with a jet pipe in the interior of the reaction furnace is arbitrary and can be done simply or repeatedly, hanging from above, from the bottom upside down or from the sides of the combustion chamber forth.
  • reaction temperatures can be up to 1100 ° C and
  • Fig. 1 shows a preferred embodiment of the burner according to the invention with jet pipe in a schematic representation.

Abstract

L'invention concerne l'utilisation d'un type déterminé de brûleur pour chauffer des réacteurs de conversion de chlorosilanes. Selon l'invention, ce brûleur présente un tube radiant et ce tube radiant entoure la flamme et le tube à flamme de manière étanche aux gaz, ce qui permet d'éviter que l'air de combustion et les combustibles gazeux et/ou liquides ainsi que les gaz de fumée pénètrent dans l'espace du four de réaction. L'avantage de cette configuration est que les gaz de fumée sont totalement séparés de l'intérieur proprement dit du four de réaction, ce qui rend impossible toute interaction critique entre l'humidité des gaz de fumée et les chlorosilanes en cas de rupture du système renfermant les chlorosilanes. Cet avantage permet d'utiliser des combustibles gazeux ou liquides pour chauffer un tel four à réaction. Un apport local excessif de chaleur par contact direct de la flamme est empêché, l'apport de chaleur est homogénéisé.
