.... The emission gas is in a lower temperature range (approximately 250 °C, or 480 °F) than for chemical incineration and can be handled by alternate technology such as a dry flue gas system. Where the gas is kept dry and above its dewpoint (the HCl dewpoint), carbon steel construction is very common. Where fabric...

..., or in ratio, air to gas. Typically in reverberatory furnaces, this is a 10 to 1 air-to-gas mixture. By analyzing the flue gases, a technician can determine if indeed the system is running at peak efficiency. This can also be done with a manometer to test pressure (inches of water column) of gas and air...

The CaCO 3 is separated and recycled into the kiln feed, and the K 2 SO 4 solution is heated to produce crystals of the same composition, which can be sold as a byproduct...
