Secondary air of sulfur furnace

Is there a secondary air setting for the stove? What we set up is the secondary air at the furnace end. The secondary air volume is about 10 to 15% of the primary air volume.

This depends on the structure of your plant's sulfur furnace. If it is a Kemedi furnace, there is no need for secondary air. Ordinary furnaces generally have a secondary air duct in the middle of the furnace. In fact, as long as the furnace volume is sufficient, it is not a big problem whether the secondary air can be turned on or not. The secondary air volume should be adjusted according to the furnace outlet temperature. This post was last edited by qingzz1965 on 2008-1-14 23:44 ]

It's a sulfur furnace, not a boiling furnace. The furnace type is Monsanto type. Horizontal diameter 4500 length 12000.

The Camidi type sulfur furnace is a primary enlarged furnace with a cyclone. The mixing is relatively sufficient and the sulfur flame is not too long, so it is generally not necessary to install a secondary air. The Monsanto furnace is a straight furnace type without a cyclone. The mixing at the furnace head is not very complete and the roasting intensity is relatively high, so a secondary air must be installed. The opening of the secondary air depends on your own experience. Personally, I think the basis for adjustment depends on the temperature of the furnace outlet pipe. If the outlet temperature is higher than the furnace tail, increase the opening of the secondary air valve. If the outlet temperature is less than or equal to the furnace tail temperature, it means that the opening of the secondary air valve is OK. The purpose of opening the secondary air is to reduce the length of the flame and ensure that the liquid sulfur is fully burned in the furnace. Otherwise, sublimated sulfur is easily brought into the boiler. Personal opinion, for reference only.
