    burnham steam boiler question

    same job another promblem so here it goes ,after seeking advice from a old timer about a very promblematic steamer he advised me to down fire the gas train by removing and plugging a couple of the orifices on the gas train and leave the burner tube in place ,i did not size nor install this boiler but i,m trying to get it so tenants don't complain his train of though was and is that the boiler makes steam to fast ,so fast the condensate returns can not handle it giving alot of banginmg upon the first 1 hour of running after that she is pretty quite ,the landlord staed that the new boiler is a little oversized and that the one it replced was a little to small ,in short the new landlord has owned the building for about 10 years prevous owners did not do any maintance on the system like cleaning returns and such and the new landlord is trying to correct things but he has had alot of steamdummies there and they have made a couple of issues worse like replcing a 2 1/2 wet return with 1 1/2 copper ,replacing that with the proper line is probalbly outta the question under stairs under ground ,so how many burners would be the limit of what can be removed the burner assembley cocnsistes of 30 burner tubes thanks peace and good luck clammy

    Removing and plugging burner orifices is not the acceptable method of downfiring a gas steam boiler. From your description and quantity of burners I would venture to guess that you have one of our Series 5B Commercial Cast Iron Steam boilers such as a K5011B. You will need to contact our Commercial Cast Iron division with the Model and Serial numbers of this boiler as well as the gas type and they can advise as to how far you can safely downfire this boiler. This will involve replacing all of the burner orifices. If you wish, let me know the Model and Seial numbers and I will contact them for you. Hope this helps.

    bad install

    Thanks for the responce both frank and glen ,as for the edr of the connected load the landlord has a list of all the rads and i should have a hold of it this week like monday ,the main promblem is that as far as i see is there was is a great difference in water levels of the old boiler compared to the new one and that as a cure they added f and t to some of the end of the main drips because they where getting no steam distrution ,there aslo was amain drip which was plugged and one main containing these f and t where not draining and where hammering sevrely ,i removed the f and t installed loop seal and the main do not hammer but the returns which are above the water line are hammer about 1/2 hour after the all the mains are hot ,there's alot going on and alot of very bad bandaids like a under ground return which was replaced from a 2 to a 1 1/2 the boiler piping and hardford loop and steam mains in the boiler room are pitched incorrectly ,as for the tags on the boiler well the plumber who replaced the boiler left nothing on the boiler no info package nothing he also was sued by the landlord over the job ,the landlord has had over the last 3 years has had alot of plumbers there do ing what i have no idea but they have been taking the landlord money with no results ,the biggest promblem is i believe that the origuinal water line was over 30 inches taller then this boiler ,and after being there yeaterday and doing some measuring it seems that i found a mark on the inside of the boiler room s door that is about 10 inches higher then my mark and woulkd cover the returns but there's returns from apartment above the garges mains which i also believe where ran and tied into the returns seperatly but as returns where replaced i believe the guys just tied then in not understanding that the reason they where tied in down the line was to gain a loop seal ,there's still alot of BS that was done and each day i go there i find more and more bad theings ,i've also replaced the pressure troll to a pa404 cut in .05 diff at 1 and that alone seemed to quite it done alot from the 1 to 3 settings on the original pressuetrol ,the mark that i found (on doorway)if correct and to the best of my snopping around if from the lowest carring steam line is about 28 inches from the bottom on that pipe as that mark compares to the new boilers water line well ,the new boilers water line is about 6 ft below that lowest carring water line ,teh landlord has stated that there was never any condensate pumps or f and t's before this boiler was indstalled or before they statred to replace some bad returns thanks for any new ideas to cure this mess ,PS i was just brough in by anorther plumber who knows nothing about steam but enjoy cllecting checks ,i looked gave him some thoughts about what i had seen and the next thing the landlord is calling me so i did a walk through with him made some suggestions and he called me again asked if i coulkd straighten this mess out so i started friday with just the ovious things like bad main vents just pissing steam and the pressuretrol and removing those f and t 2 more to go and start to lkook at the false water ,steam head what are your feeling about this am i missing something with concerning the water line and glen after i gett the connected edr i'll contact burmhams commerical div and see about down sizing the orifices i feel that this boilers oversized by at least 100 btu ,as i told the landlord fixing this sytemn is not a bang bang thing that all you had done for 3 years and none of the promblems have disappeared peac and good luck clammy
