The following two methods are usually used to deal with the recycling of traditional steam generators.
One is to consider from the aspect of air preheater. The air preheater with the heat pipe as the key heat transfer part is selected, and the heat exchange efficiency can reach more than 98%, which is higher than that of ordinary heat exchangers. This air preheater device is light in design and occupies a small area, only one-third of the ordinary heat exchanger. In addition, it can effectively avoid the acid corrosion of the fluid to the heat exchanger and increase the service life of the heat exchanger.
The second is to start with mixed water recovery and treatment equipment. Sealed and pressurized high-temperature mixed water recovery and treatment equipment can directly recycle part of the relatively high-temperature flash steam and high-temperature condensed water, and use high-temperature steam-water mixed recovery to directly recover and press it into the steam generator to form steam-using steam- —Closed circulation system for regenerating steam to improve the effective heat utilization rate of steam. It also reduces the loss of electric energy and salt energy, i reduces the steam generator load, and reduces a large amount of soft water.
The above content is mainly a brief description of the technical issues of waste heat recovery from steam generators, and it is still necessary to think carefully about specific issues.
