New ideas for energy savings – Creative uses for steam condensate
Thread Content
This post is not about proposing any new ideas or concepts, but rather using this event as an opportunity to discuss them. Many enterprises use externally supplied steam; the steam suppliers are generally enterprises such as thermal power plants. For safety reasons, thermoelectric power plants are reluctant to return the condensate generated by users, in order to prevent chemicals from the users from leaking through the equipment and mixing into the boiler water. In this case, how can steam users make full use of condensate?
The condensed water from the sulfur melting process using sulfuric acid is returned to the circulation tank to replenish the soft water
Returning to the power plant after heat exchange is a good option
After treatment, the condensate water from our company is used: part of it is employed as circulating water, while a small amount is mixed into desalinated water.
Can be used as a substitute for soft water, industrial water, make-up water for circulating water, water for cleaning on-site containers, cleaning water, etc., as needed
I came across a project for the recycling of condensate water, but it wasn’t me who worked on it. The general process is as follows: the steam at the beginning has a pressure of 10 MPa; the condensate water produced is then depressurized to produce steam at 6.5 MPa, which is then used ； Then, the condensate produced by 6.5 MPa steam is depressurized to become steam at 1.0 MPa for use. However, the situation varies from company to company; if it is mostly low-pressure steam and there are not many usage points, then replenishing water for the circulation tank is still the better option. There’s one thing that has been bothering me: will the collection of this condensate water in the recirculation tank increase the load on the cooling tower? Has it increased energy consumption again?
Our company is responsible for providing make-up water for circulating water and water for biochemical processes
Use a plate heat exchanger to cool down and recover heat, then direct it to where soft water is needed~
