The Difference between Waterback and Dryback Boilers - The Boiling Point
HTML-код
- Опубликовано: 15 май 2016
- On today's episode of The Boiling Point, Gerald and Ritchie address a topic that WARE gets a lot of questions about-the difference between waterback and dryback boilers.
Chapters:
Dryback 1:41
2-Pass Waterback 8:49
3-Pass Waterback 9:58
A dryback boiler design means that the rear wall is lined with refractory. As an example, Gerald shows us a dryback boiler by Victory Energy that is engineered to optimize water circulation, promote heat transfer, and engineered for long-term performance and reduced maintenance. Using a dryback boiler, you can use up to 10% less fuel.
Waterback boiler designs have a water gap between the furnace and back wall, and all of the heat is generated directly into water. Waterback designs are just as durable as dryback designs, but must have a heat balance in the system.
Be sure to watch the entire video for a very important announcement from WARE.

Great video and learning tool! Thanks!
i appreciate your explanation. nice one
So Clearly explained Highly appreciated
Glad it was helpful! Thanks for watching!
Thank you for your beautiful information
Awesome episode! I starting reading boiler thinking taking some courses
Thanks for watching!
I dont Completely agree with Dry back retaining so much heat to actually act as a heat accumulator but i do agree with dry back being more accessible.
Of course it does. Insulated refractory does reduce heat loss due to high porosity distributed evenly. Result: less thermal conductivity.
Wow, nice video thank you
Sir, question with regards to the rifled tube increasing the heating surface, to the maintenance side, on PMS of tubes, is there no problem in removing minimal deposited soots on rifled tube? what are other means aside from using rotary brush?
impressive!
Good info
Really appreciate the comment. We try to get information out there that's both interesting and helpful. Please make sure to like the video and share it! Thanks!
وشكرا لكم على الفيديوهات المفيده جدا
muy bueno la clarificacion en e tema de diseño y perfomance de calderas pirotubulares,como el esplicativo de la transferencia de calor a lo largo del recorrido de los gases por los distintos pasos del
generador de vapor
Disculpas si esto se lee extraño, yo estoy usando Google Translate. ¡Gracias por tu comentario! Por favor, comparta lo que podemos obtener esta información por ahí. Este es un gran tema que queremos para asegurarse de que todo el mundo entiende la diferencia. ¡Que tengas un gran día!
Excellent. What is a surface blow down.... We normally see bottom blow down.
Also, what is the advantage of surface blowdown.
Thanks for your valuable time.
Take a look at our video here ruclips.net/video/d5N8rbBoGJE/видео.html and see if that helps out. We are actually looking at doing a Weekly Boiler Tips on surface blowdown here soon!
@@wareboilers Thanks for your excellent video.
Some dissolved solids in water that are distilled behind when water evaporates Float and Some sink. The dissolved solids that float need surface Blowdown and the ones that sink need Bottom Blowdown.
10:47 to get to the definition
Nice
It's confuse that dry back refractory acts as a thermal sink. Because this energy ever comes from the burner. But all of this is a very interesting explanation
What is a "Zero Expansion Module"? Time stamp 8:35
How can I learn more about boiler designs and maintenance from Rwanda?
Google and RUclips are incredible and free resources

Fery Nice Best of the Best firetube steam boiler with neck
It at all reassuring
Ware werks, we yanks keep em up at night and appreciate the completion
good
and cute both
How to Ready for Boilar in rice mill
Not sure what you mean. Are you asking about getting a boiler ready to operate?
I always though dryback was someone who came here legally... i know bad joke... good presentation
Nice video.But NOX at 30 ppm....this something i would like to see :D
It's possible! Using systems such as the Limpsfield Burner and an Autoflame Controller you can dial down the NOx to 30 ppm with varying degrees of efficiency. You can check more out here www.wareinc.com/combustion and please give us a call if you have more questions, we would be happy to help. Thanks for the comment!
isn't one made in mexico?
I love your comment.
Victory Energy boilers are actually manufactured in Oklahoma. Appreciate your comment and thanks for watching.
Jimmy Doe, Was going to make that joke too! XD
I don't get it?
Only talk about boilers
We are! Boilers are all we know! Haha Thanks for watching!
I am thinking go back to my country and save your phone number guys. To get some boilers to my country El Salvador. I actually in new york Now
For Mexican’s only
Not explained well
