Series 3 - Packaged Firetube BoilerSave Thousands Of Dollars Over The Life Of Your BoilerLong-term energy and maintenance efficiencies are the focus of Burnham quality engineering. When choosing a boiler, it’s a good idea to select a product with these features in order to reduce enormous hidden costs down the road. Review our wetback versus dryback literature for cost savings.

Boiler Costs Is Not Jus A First Year PropositionWith any ordinary boiler, expenses such as fuel, maintenance, and repair costs can escalate as the years go on. Burnham packaged boilers are designed to diminish these significant expenditures.

Burnham’s High Life-Cycle EfficiencyWhile most competitive boilers can give fuel-to-steam efficiencies of 80% or over—when they’re new—how consistently can they be expected to maintain this level of operation? Burnham wetback boiler performance will not drop due to deteriorating rear refractory, leaking door baffles and seals, and heat-stressed rear tube sheet as can happen with some drybacks. Easy access is a necessity for those with heavy refractory, since they need frequent and expert maintenance.

The Burnham Wetback Saves Big Money On MaintenanceOver the life of a dryback, brittle refractory baffling and rear door gasketing will require continuous monitoring, maintenance, and replacement, costing thousands upon thousands of dollars. These built-in maintenance costs can eventually equal or exceed the original cost of the boiler. As refractory deteriorates, leaking hot gas causes boiler efficiency to drop until the condition is noticed and the repairs can be made. Expensive flue temperature alarms are offered with some drybacks to monitor this dangerous and costly potentiality. The rear door itself can become heat-distorted, requiring an expensive replacement. In addition, boiler downtime during repairs can mean crippling losses.

This waste of time and money is eliminated with the Burnham Wetback. The actively functional water jacket eliminates the need for: refractory wall, rear door, rear door inspection and sealing, door swing space, and flue temperature alarm. These costly maintenance headaches are gone, while boiler performance is increased. Burnham has only a small, inexpensive refractory area in the burner area, for burner mounting. The rear access door liner is a ceramic fiber insert that contains no refractory.

The furnace and rear turnaround area are cool running, fully wetbacked radiant heat transfer surfaces. They promote good internal water circulation and rapid heat absorption. There is no need for the forced internal circulation pumps often specified to cool the rear tube-sheets and drybacks.

The Burnham Wetback Is Built To LastTypical dryback boilers have a common rear tubesheet that expands and contracts at different rates adjacent to each tube pass, stressing tube ends and increasing the likelihood of leaks. Additionally, the heavy refractory used in some drybacks reflects intense heat to the rear tube ends and tube sheet, accelerating their deterioration. In attempts to stop leaking, the rear ends of tubes have sometimes been welded. Cleaning or tube replacement involves opening both the front and rear covers and resealing them when the job is done. Usually, if tubes have been welded at the ends, the welds must be burned out, the tube sheet repaired (or a new segment welded in) and the new tubes welded.

These costly expenditures are not an issue with the Burnham Scotch Marine: separate rear tube sheets from each pass to expand and contract at its own rate without tube-to-sheet stress. Tubes are rolled and flared in low-pressure units; and rolled, flared and beaded in high-pressure units. No welding of tubes is permitted, nor is it necessary. Any eventual tube replacement is simply a mechanical operation, no welding involved. The end result is less cost and less headache.

• Ready access to tubes through rugged front door and rear covers makes routine cleaning easier and less costly than with drybacks.

• Burner does not have to be disturbed.

• No inner air baffle door to contend with.

• No delicate expensive baffle tiles or door seals to replace.

• Unlike dryback boilers, securing the doors on a Burnham wetback boiler requires no specialized skills or expensive repair materials. It is a simple process which can be done with in-house personnel and performed with minimal downtime.

• Large, fully waterbacked furnace tube assures complete combustion and heat absorption without flame impingement.

• Three gas passes extract maximum usable heat from the fuel while maintaining optimum flow for forced draft firing.

• Fully waterbacked reversing chamber effectively absorbs radiant heat into the water, keeping tube ends and rear of boiler cooler than those of hot-running drybacks.

Wetback Design vs. Hard Refractory Dryback DesignWhy is a Wetback design better?Burnham’sthree-passwetbackdesignhasarearwaterwall,whichseparatestheprimaryheatingsurfaceofthecombustionchamberfromthereartubesheet.Thewaterjacketeliminatestheneedforarefractorywallandreardoorswingspacebehindtheboiler,aswellascostlyrefractorymaintenance.

Therearwaterwalleliminatestheneedforgasketing,whichisvulnerabletothetemperaturegeneratedintherearoftheturnaroundarea.Awetbackdesignboilernotonly overcomes these expensive deficiencies, but it has great overall efficiency and virtually maintenance-free construction.

A Burnham boiler will cost you less over the lifetime of the boiler because it is better by design!

Some Points to Remember:Wetback Advantages• Wetback boilers have separate tube sheets between all major temperature changes.• The rear access door is constructed of lightweight ceramic fiber• Thereardoorsrequirenocool-downperiodandcanbeopenedimmediately• Nospaceconsumingarearequiredfortheswingdoor• The split rear flue doors are easily removed • Efficiency is readily maintainable because the design of the boiler promotes complete and even circulation of flue gases

WhAT IS FuEL-TO-STEAM EFFICIENCY AND IS IT IMPORTANT?Fuel-to-steam efficiency is very important because it is the only true measure of overall packaged boiler operational efficiency. True fuel-to-steam efficiency takes into account radiation and convection heat losses, which less reputable manufacturers may ignore. We suggest purchasing your boiler from a manufacturer who guarantees fuel-to-steam efficiency in the performance of your entire packaged boiler. Be wary of misleading efficiency terms, such as “thermal efficiency” or “combustion efficiency”. Contact your local Burnham Commercial sales representative for further defini-tion.

MAINTAINABLE EFFICIENCY VS. ATTAINABLE EFFICIENCYWhen looking at efficiency as criteria for purchasing a boiler, especially fuel-to-steam efficiency, the manufacturer’s design efficiency sets theoretical fuel costs while operation efficiency determines actual fuel costs. There is a differ-ence between attainable efficiency and maintainable efficiency. Correct burner adjustments are the key to maintain-able efficiency. It is a compromise between the optimum and the practical. Good burner tuning is achievable only with agoodburnerdesignandagoodburner/boilerpackage.

WILL A DRYBACK BOILER COST MORE TO OWN?The answer is simple…Yes! The high cost of maintenance is the biggest consideration in overall efficiency in a dry-backdesign.Considerthisexample:anaverage�00HPboileroperatingundernormalconditionswithaconserva-tivelifespanof��years.Oursurveyshaveshownthatduringthisboiler’slifetimethereardoorrefractorywouldbereplacedabout8times(roughlyeverythreeyears).Also,assumingtheboilerisopenedonlyonceayearforinspec-tion,regasketingofthereardoorwouldoccur��times.

Follow the “Pressure From...” down vertically on the chart at left to the “Pressure To...”.

Example: 75 PSIG condensate flashed to low pressure heatingsystemat1�PSIGgives7.6% condensate flashed into system.

After determining the percent of flash from the chart above, determine the size of Flash Separator from the chart below.

Example: Referring back to the chart above, you have a 7.6% flash, If you have 30,000 #/hour condensate at 75PSIG, 2,280 #/hour steam (30,000 x .076). Locate 30,000 in the left column below, go across to 2,280 #/hour flash steam column (3,000). You would use a 56” high x 18” diameter Flash Separator with a 3” draft and 5” vent.
