Problems with furnace drying in new sulfur production facilities
Thread Content
Our company has newly installed a set of sulfur-related equipment. There is a problem: during the initial heating-up phase of the new furnace, it is planned to maintain a constant temperature at a certain level (above 800°C) for an extended period of time. Is there any danger or risk associated with this approach? If so, how can such risks be prevented? Please offer as much help as possible. Thank you!
Staying at a constant temperature of 800 degrees for a long time poses no danger.

For furnace drying, just follow the drying curve; if it is in hot standby mode, maintaining a temperature of 800°C is also acceptable.
Due to special requirements, we need 3.5Mp steam for target shooting; purchasing such steam is not permitted under the current conditions. Initially, it is considered for use in furnace drying for internal production. I’m just worried that maintaining this temperature for such a long time might have an impact on the equipment. Please advise
It’s a meaningful question; learn about it!
Please also invite professionals to provide guidance; thank you
It is recommended that the first furnace drying be carried out strictly in accordance with the curve provided by the manufacturer; the approach of using self-generated steam for steam testing requires further evaluation. For medium-pressure steam fed into the turbine, it is necessary to perform line purging; when the amount of steam generated is low, this has little impact on the system, and purging is not required. Instead, use 1.0 MPa steam to purge the lines repeatedly.
What is steam target shooting? Please explain it. It should be carried out according to the furnace heating curve; generally, there are two constant-temperature stages, right? Steam is used for temperature control.
If that’s the case, what happens when the device is operating normally at temperatures above 1100 degrees for an extended period of time? Once a better device is available, it can be in operation for half a year without any downtime; so there’s no need to worry about that issue. Using 800-degree steam produced locally is excellent.
Theoretically, there should be no problem. But it’s not known what problems might arise in actual operation. So I’m coming to consult those who have practical experience
As long as operations are carried out in accordance with the furnace heating curve, that will be sufficient. It is also important to pay close attention to the flame condition inside the furnace; due to the high temperatures, it is easy for the furnace tubes to get damaged, so extra care must be taken in this regard. Additionally, attention should be paid to the liquid level in the fuel tank to prevent the burner from going out. When cooling down, it is necessary to do so slowly to prevent sudden drops in temperature from causing cracks inside the furnace.
