Selection of deoxygenation methods for boiler water
Thread Content
Boilers are used in sulfuric acid production, and steam is generally employed for deoxidizing the water used in these boilers; this not only wastes steam but also looks unsightly, as people might think that the steam coming out is exhaust gas. In an era where energy is receiving increasing attention, improving steam conservation is something that every enterprise must consider. We generate electricity from the waste steam, reducing the amount of steam used in order to produce more electricity; therefore, we have an idea to eliminate the use of steam for deoxidization and instead use resin for that purpose. Which factories have already adopted this method? Is it cost-effective from an economic perspective? Please upload some materials. Thank you!
Compared to thermal deoxidation, the process of using resin for deoxidation and hydrazine hydrate for regeneration requires a higher initial investment, and the output water is at room temperature. In fact, thermal deaeration does not result in any waste of steam; this steam raises the temperature of the feedwater, thereby increasing the steam production. The heat from the heating steam is still in the energy circulation system. As for the steam discharged from the deaerator, it can be considered for reuse. Our company has carried out renovations; there is no steam emission or noise at the site. You have the chance to come and visit our company.
Thank you! What organization are you from, buddy? Could you talk about how to make improvements? This post was last edited by LU66 on 2007-12-16 19:52]
I would like to ask how the steam emitted by the deaeration head is recovered and reused. Thank you!
We direct the exhaust steam from the deaeration head into a idle small heat exchanger, which is used to heat the demineralized water fed into the deaeration tank. The problems with steam emissions and noise are solved.
This method is excellent; moreover, the exhaust steam and water from fixed-row and continuous-row arrangements, as well as those from sulfur insulation systems, can all be recovered.
Good, let’s give it a try too. Thank you. http://bbs.hcbbs.com/images/smilies/default/handshake.gif
We face the same problem: the methods of recycling
I heard that resin deoxidation is no longer the most advanced method; let’s discuss what the best way to remove oxygen is ? ? ?
