Series 3 - Boiler

The Burnham Wetback Packaged Boiler Can Save You Thousands of Dollars Over the Life of Your Boiler. Burnhamquality engineering takes maximum advantage of long-term energy andmaintenance efficiencies. Unless you take those efficiencies intoconsideration along with price when you choose a boiler, you can be infor enormous hidden costs.

The Series 3 matches burner to boiler, providing a fuel efficientlow-maintenance package. It takes maximum advantage of long-term energyand maintenance efficiencies.

Boiler Cost is Not Just a First-Year Proposition.
Long after the installation is paid for, fuel, maintenance, andrepair costs continue and can increase over the years. Burnham PackagedBoilers are designed to minimize these significant, ongoing ownershipcosts.

That's Burnham's High Life-Cycle Efficiency!
While most competitive boilers can give fuel-to-steam efficienciesof 80% or over-when they are new-how consistently can they be expectedto maintain this level? Burnham wetback boiler performance will notdrop due to deteriorating rear refractory, leaking door baffles andseals, and heat-stressed rear tube sheet as can happen with somedrybacks: the fact is that easy access is a necessity for those withheavy refractory, as they need frequent, expert maintenance.

The Burnham Wetback Saves Big Money on Maintenance.
Over the life of a dryback, brittle refractory baffling and reardoor gasketing will require continual monitoring, maintenance, andreplacement, costing thousands upon thousands of dollars. Thesebuilt-in maintenance coats can eventually equal or exceed the originalcost of the boiler As refractory deteriorates, leaking hot gas causesboiler efficiency to fall until the condition is noticed and repairscan be made (expensive flue temperature alarms are offered with somedrybacks to monitor this dangerous and costly potentiality). The reardoor itself can become heat-distorted, requiring an expensivereplacement. In addition, boiler downtime during repairs can meancrippling losses.

This waste of time and money is eliminated with the BurnhamWetback: as it has an actively functional water jacket, there is noneed for a refractory wall, rear door, rear door inspection andsealing, door swing space in the boiler room, or flue temperaturealarm. These costly maintenance headaches are gone, while boilerperformance is increased. Burnham has only a small, inexpensiverefractory area in the rear access port. The furnace and rearturnaround area are cool running, fully wetbacked radiant heat transfersurfaces. They promote good internal water circulation and rapid heatabsorption. There is no need for the forced internal circulation pumpsoften specified to cool the rear tube-sheets in drybacks.

The Burnham Wetback is Built to Last.
Typical dryback boilers have a common rear tubesheet which expandsand contracts at different rates adjacent to each tube pass, stressingtube ends and increasing the likelihood of leaks. Compounding thisproblem, the heavy refractory used in some drybacks reflects intenseheat to the rear tube ends and tube sheet, accelerating theirdeterioration. Sometimes, welding of the rear ends of tubes has beendone in attempts to stop leaking. Cleaning or tube replacement involvesopening both the front and rear covers and resealing them when the jobis done. Usually, if tubes have been welded at the ends, the welds mustbe burned out, the tube sheet repaired (or a new segment welded in) andthe new tubes welded also.

These damages and expenses cannot be incurred with the BurnhamScotch Marine; separate rear tube sheets free each pass to expand andcontract at its own rate without tube-to-sheet stress. Tubes are rolledand flared in low pressure units; and rolled, flared and beaded in thehigh pressure ones. No welding of tubes is permitted, nor is itnecessary. Any eventual tube replacement is a mechanical, not awelding, operation: uncomplicated and less costly.

It All Adds up to Significant Cost Performance Advantage.
These energy and maintenance features add up to real savings foryou. Our design for long-term efficiency and economy of operation makesBurnham Packaged Wetback Firetube your cost-performance leader!

Burnham Scotch Marine Boilers match burner to boiler, providinga fuel-efficient, low-maintenance package. Maintenance costs can befurther controlled in your boiler room with optional accessories. Suchoptions include state-of-the-art annunciator systems, custom-designedto monitor all boiler and burner interlocks vital to your particularinstallation. They provide instant readout of both normal and abnormaloperating conditions, pinpointing any causes for unscheduled shutdowns,and reducing maintenance time and skill required.
