Abstract
A furnace and a process for temperature control of a material stream, wherein the furnace has a first combustion chamber, at least one reactor tube for receiving the material stream to be heated, and at least one second combustion chamber. The at least one reactor tube extends through the first combustion chamber and through the at least one second combustion chamber. The furnace is designed to establish a first temperature in the first combustion chamber and a second temperature in the at least one second combustion chamber, wherein the first temperature and the second temperature are separately adjustable.
Claims17
A furnace having a first combustion chamber and at least one reactor tube extending through the first combustion chamber for receiving a material stream that is to be heated, characterized in that the furnace has at least one second combustion chamber through which the at least one reactor tube also extends wherein a first temperature generated in the first combustion chamber and a second temperature generated in the at least one second combustion chamber are each adjustable separately.
A process for heating a material stream in at least one reactor tube of a furnace the process comprising heating the material stream in a first combustion chamber of the furnace, to a first temperature, and subsequently heating the material stream to a second temperature in at least one second combustion chamber of the furnace, wherein the first temperature and the second temperature are separately adjustable.
The process according to 12, characterized in that olefins are ethene propene.
