Precise operation methods for pyrite spot furnaces
Thread Content
Dear experts, I’m hoping to get the exact steps for lighting a furnace using pyrite. In the past, wood was used for this purpose, but it’s very difficult to control the process, and scorching often occurs. What are the specific steps for using river sand (yellow sand) instead? Also, what are the details of the process involved in lighting the furnace with it? Thank you very much everyone
This section contains some introductions and discussions on furnace operations; you can find out more by searching for it yourself.
Scarring has nothing to do with the furnace firing method; it is mainly caused by operational controls, so management in this area needs to be strengthened.
It seems that using sulfur to ignite is still the best option.
5# qiqibuzaiao: What is the area of the furnace you want to use? The process of starting the furnace depends on its size; for a furnace of around 8 square meters, it’s possible to start it without any fuel. For larger furnaces, those over 10 square meters, a certain amount of screened red slag needs to be added to the furnace, and data regarding cold boiling must be collected in order to prepare for starting the furnace. When lighting the fire, make sure that the temperature inside the furnace rises enough; once there’s sufficient heat, the current required to operate the fan can be set at the level corresponding to cold boiling conditions. Add an open flame at the furnace inlet, along with sulfur. With proper handling, the furnace can be started in less than ten minutes. Be careful to avoid explosions, and have some red slag ready.
It is likely that the issue is caused by too low pressure at the bottom of the furnace during your operations. We have encountered this problem before; we recommend that you increase the pressure at the bottom of the furnace by at least 3,000–5,000 Pa compared to the current level. Don’t worry – in the old system, the pressure was around 12,000 Pa, and we used the same pressure level in the new system as well. But it didn’t work at first; we were hesitant to increase the pressure, but after trying a few times and raising it to 15,000 Pa, the problem was resolved. Give it a try. These are my personal opinions; please feel free to correct me.
