Selection of heating furnace for commissioning
Thread Content
Before putting an industrial furnace into operation, its lining needs to be heated, with the required temperature reaching up to 1000°C. I would like to ask everyone: which type of heating furnace would be more suitable in this case? Additionally, I am looking for technical information related to heating furnaces.
I’d like to ask politely: is this regarding the first start-up of heating the lining, or is it a normal operation? Are there any other special requirements for the furnace? From our understanding of the question, it seems quite simple: fuel is introduced, and the temperature is increased gradually according to a specific heating curve until the desired temperature is reached; for example, in the case of a hydrogen production converter, when the temperature reaches 1000°C, operation proceeds using the aforementioned method. This process has no direct relation to the type of furnace. Additionally, technical information related to heating furnaces can be downloaded from a forum – it provides a comprehensive overview of furnace design
Reply to Floor 2: First of all, thank you for your active participation! The method you mentioned is correct; we have been using it as well. Now we want to design a heating furnace outside the furnace, to be used for both the initial drying process and subsequent operations. The goal is to avoid having gas burn directly inside the furnace. I hope I explained this clearly.
An auxiliary combustion chamber similar to that used in catalytic cracking can meet the above requirements: it facilitates intense combustion within the furnace to heat the air, which is then sent to the equipment that needs to be heated. For such a system, in addition to the combustion chamber, blowers and control valves must also be installed
It’s similar to having an external burner configured. Our company manufactures oven drying machines, which are specifically used for drying the linings of furnaces, and can also be used for starting up furnaces.
