Utilization of waste heat from corrosive gases
Thread Content
Is there suitable equipment to generate low-pressure steam from the 260-degree waste heat of smelting flue gas? I would appreciate your advice.
(Forwarded) The waste heat at 260 degrees from smelting flue gas is used in the rear waste heat boiler; it is essential that there be no water present, and the drying process must be thorough – otherwise the materials used will be very expensive
It’s too general; there are various types of smelting gases. What are the components of the smelting gas you use? Only after knowing the components can one consider an appropriate method for waste heat recovery.
The flue gas resulting from the roasting of zinc, after dust removal, is used to produce sulfuric acid; it contains about 6-8% SO2, as well as certain amounts of F, Cl, dust, and water vapor, making its composition complex and requiring purification before it can be used in sulfuric acid production. The main goal is to reduce the temperature of the flue gases, while generating a certain amount of steam for use in production. If more parameters are needed, please let us know.
It’s difficult if it has to be dried, as there is a lot of moisture; the key issue with drying is also the risk of equipment corrosion
There’s no need for drying; it’s sufficient to lower the temperature so that it doesn’t reach the dew point. There are many manufacturers of waste heat boilers, so just find one
We have worked on similar projects; could you provide the specific parameters so that we can have a plan for reference? QQ: 506925142. Verification: heat pipes, waste heat boilers.

A waste heat boiler can be used. It uses low parameters, has low requirements for the material of the metal heating surfaces, the equipment needs to be replaced after being in use for a certain period of time, and thus maintenance costs are low.
