Series 3 - Boiler

The Burnham Wetback Packaged Boiler Can Save You Thousands of Dollars Over the Life of Your Boiler. Burnham quality engineering takes maximum advantage of long-term energy and maintenance efficiencies. Unless you take those efficiencies into consideration along with price when you choose a boiler, you can be in for enormous hidden costs.

The Series 3 matches burner to boiler, providing a fuel efficient low-maintenance package. It takes maximum advantage of long-term energy and maintenance efficiencies.

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

That's Burnham's High Life-Cycle Efficiency!
While most competitive boilers can give fuel-to-steam efficiencies of 80% or over-when they are new-how consistently can they be expected to maintain this level? 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: the fact is that easy access is a necessity for those with heavy 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 rear door gasketing will require continual monitoring, maintenance, and replacement, costing thousands upon thousands of dollars. These built-in maintenance coats can eventually equal or exceed the original cost of the boiler as refractory deteriorates, leaking hot gas causes boiler efficiency to fall until the condition is noticed and 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: as it has an actively functional water jacket, there is no need for a refractory wall, rear door, rear door inspection and sealing, door swing space in the boiler room, or flue temperature alarm. These costly maintenance headaches are gone, while boiler performance is increased. Burnham has only a small, inexpensive refractory area in the rear access port. The furnace and rear turn around 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 in drybacks.

The Burnham Wetback is Built to Last.
Typical dryback boilers have a common rear tubesheet which expands and contracts at different rates adjacent to each tube pass, stressing tube ends and increasing the likelihood of leaks. Compounding this problem, the heavy refractory used in some drybacks reflects intense heat to the rear tube ends and tube sheet, accelerating their deterioration. Sometimes, welding of the rear ends of tubes has been done in attempts to stop leaking. 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 also.

These damages and expenses cannot be incurred with the Burnham Scotch Marine; separate rear tube sheets free 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 the high pressure ones. No welding of tubes is permitted, nor is it necessary. Any eventual tube replacement is a mechanical, not a welding, operation: uncomplicated and less costly. 

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

Burnham Scotch Marine Boilers match burner to boiler, providing a fuel-efficient, low-maintenance package. Maintenance costs can be further controlled in your boiler room with optional accessories. Such options include state-of-the-art annunciator systems, custom-designed to monitor all boiler and burner interlocks vital to your particular installation. They provide instant readout of both normal and abnormal operating conditions, pinpointing any causes for unscheduled shutdowns, and reducing maintenance time and skill required.
