- Undesirable, throw-away, non-repairable construction is avoided
(as seen on some watertubes and exotic designs)
- Our FIRETUBE design has 100% water-cooled heat transfer surface;
no hot fins to burn away
- High efficiency is obtained without using a fourth pass; fourth
pass tubes have often been subject to premature failure.
- FIVE square feet of heating surface for each boiler horsepower
- Time-tested design, 35 years in the field and now with refined
features
- Hinged front doors provide fast access to tubes without disconnection
of pipes, fuel lines or electrical cables AND without disturbing
firing equipment
- Shipped completely assembled and factory test-fired
- Ample steam space and steam release area yield dryer steam
and minimize scaling of system components
|
Excellent Rear Access
- Separate rear doors offer simpler, faster access
- An extra 15-inch quick access inspection port is nested in
the lower rear door
- Split rear doors reduce refractory use and attendant maintenance
costs
Refractories are of the field-replaceable, castable variety;
no special expensive blocks or bricks
- Extra handholes are provided in a superior location in the
front tube sheet below the furnace
- Offset handhole plate studs ease insertion and removal
|
Unique Twin Head Design
- Two rear tubesheets, one for each pass; uneven stress is eliminated
- Water-cooled pass divider plate; this prevents short circuiting
even if refractory needs repair
- Twin tube sheets eliminate need for welded tube attachment
(welded tubes are more difficult to replace)
- Large 5/8" BOLTS are used on all doors; fewer are required;
opening/closing is faster; easily damaged studs are avoided
- All fireside doors have long-life gaskets, fit for repeated
use
