Unfortunately,as a relatively small steam generator, you are being sold a product that is formulated to be the "one size that fits all".This is a common marketing effort to satisfy a large group of users where each user over uses some products in the blend to gain an effective concentration of...
Firstly, You should know that your deaerator is not functioning effectively... It should not produce oxygen levels above 7ppb.. I would fix the deaerator befor looking at anything else......Countryham
I have been challenging past methodology and thinking about oxygen scavenger applications in deaerators for a long time. Current knowledge suggests that it is advantageous to carry a 5ppb dissolved oxygen residual in deaerators and consequently all feed water equipment.Lower oxygen residuals...
The subject has been pretty well covered here. I have been mulling over these ideas for many years and I have never seen anyone address the improper use of available sodium hydrosulfite sources to chlorinate potable (drinking water). I don't think that anyone has addressed the fact that sodium...
Yes, there may be a way to do it cheaply, as I did thirty years ago... Tell me more about your water supply... High turbidity?.. Kind of chemical treatment?... Storage capacity? Residence time?
I have used all three over the past thirty five years.. I have done about everything that can be done (wrong) while by making poorly assumed "educated guesses"....I have found nothing that compares to alum as a surface water coagulant but alum has at least two shortcomings.-1.It forms three...
The earlier responses to your message were unquestionably "on Target"... I never heard of anything like that! and I've been to a whole bunch of county fairs......There is one thing for certain that has been well researched back to the pre 1940,s............The combination of carbon dioxide and...
I have been building a file on phosphates for over thirty five years and I have not found one true "authority" on this subject.The generally accepted view has been in use since Calgon patented the use of hexametaphosphate in municipal water supplies many,many years ago...
Reply to Kenvlach,--Of course, I am interested in any/all systems that have a proven or highly suspected failure due to FAC in feedwaters,- especially those failures in industrial boiler economizers that are fitted with carbon steel and those ruptures generally in elbos and welds(highly impinged...
Thanks, eyec-- I have that one on file....If you have any other similar information, I would certainly like to know about it...As Artemus Ward (1834-1867) once said,--"It ain't so much the things we don't know that get us in trouble. It's the things we know that ain't so".--- Mail...
This (tannin ) question is a real supprise!!... Have only heard of tannin used as a scavenger one time before!Tannins and/or other organic materials similar to sodiumlignosulfate to prevent sludge from becoming adherent on boiler shell surfaces----which has been in boilerwater use since the use...
I have developed a new , greatly improved method of catalytically scavenging oxygen with sulfites from boiler feedwaters--almost instaneously (with a 4+ times greater catalytic result than ever thought possible in the past with any other (commonly accepted catalyst technology)--CONTROLLED within...
I have developed a new,greatly improved method of catalytically scavenging oxygen with sulfites from boiler feedwaters-- almost instaneously (with a 4+ times greater catalytic result than ever possible in the past with any other (commonly accepted catalyst)technology)----CONTROLLED within 1-2ppb...
Can anyone furnish any known recent(documented)corrosion or failures/ explosions in boiler feedwater systems, with or without injuries??I am looking for industrial boiler waterside failures that can be attributed to Flow Accelerated Corrosion in economizers and oxygen attack in either or both...
