1. Meanwhile, F108 was initially designed without HPSSH in convection section, and the saturated vapor generated was sent to vapor superheating furnace for superheating.

2. Based on the self- developed simulation software about convection section in cracking furnace, all kinds of key points have been compared.

3. Application of soldered finned tube to convection section of high hydrogenation heater in refinery is proved to be safe and reliable through industrial practice.sentencedict.com/convection section.html

4. The tubes in the convection section are usually finned tubes after the first two bare shock or shield rows.

5. The burst part in convection section of a tube of F108 cracking furnace in alkene factory, Liaoyang Petrochmical Company, was analyzed.

6. This article analyzes the reason for vibration in convection section for the first - stage furnace.

7. The chemical cleaning method of convection section tube for hydrogen manufacturing furnace was recommended.

8. It must be noted, however, that refinery gas usually generates a certain amount of steam in the convection section of refinery gas-fired radiant furnaces.

9. It can be used to check the flexibility of the convection section when the feed and operation condition changes, and it can be used to design the cracking furnace of different scale and feedstocks.

10. Therefore, the process feed, combustion air, and fuel gas should be preheated as much as possible before considering steam generation in the convection section.

11. After studying coke reaction mechanism and vapor - liquid - water three - phase equilibrium, we think that the coke is produced by coke precursor in convection section of cracking furnace.
