【Q&A Question 043】February 12, 2018: What are the main differences between top-fired and side-fired conversion furnaces from an engineering design perspective? The top-firing conversion furnace is a type of box-shaped furnace with combustion at the top; it features a lower flue, and the convection section is arranged horizontally or in an ∩ shape vertically. Compared to side-firing furnaces with the same production capacity, it occupies more space but is better suited for larger-scale applications. A side-fired converter features burners arranged on the side walls, an upper flue; the convection section can be located at the end or atop the radiation section, and it occupies less space compared to a top-fired converter with the same load. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limits on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

The top-firing conversion furnace is a type of box-shaped furnace with combustion at the top; it features a lower flue, and the convection section is arranged horizontally or in an ∩ shape vertically. Compared to side-firing furnaces with the same production capacity, it occupies more space but is better suited for larger-scale applications. A side-fired converter features burners arranged on the side walls, an upper flue; the convection section can be located at the end or atop the radiation section, and it occupies less space compared to a top-fired converter with the same load. In a top-fired furnace, the burners are located at the top and their number is small; as a result, the heat recovery system can preheat the air using low-temperature heat. This allows for less steam generation and less fuel consumption under the same heat load and efficiency conditions, which is beneficial for energy savings and reducing the cost of hydrogen. The side burners are distributed on both sides of the furnace; there are many of them but their power is low, which makes it difficult to use air preheaters. Under the same heat load and thermal efficiency, more steam can be produced, but this results in greater fuel consumption. Furthermore, due to the tall structure of the side-fired furnace, more steel is required.

Haven’t seen a side-burning furnace; I’d like to learn about it*
