water wall furnace. Water walls shall be on the top, bottom and both sides. No refractory or insulation shall be used on any sidewall.

2. Top, bottom and sides of the furnace shall be made up of water-cooled surfaces and shall be comprised of straight tube runs only. No furnace seal shall be made by the meeting of two tube hairpin bends.

3. The fireside of the boiler shall have five (5) longitudinal gas passes, travelling the full length of

the boiler, separated with tangential water wall tubes to insure maximum linear gas travel, increased gas side velocities and improved gas side heat transfer coefficients. Products of combustion shall flow horizontally through the boiler across boiler tubes.

4. Stainless steel cross flow turbulating baffles shall be installed in the second and fourth passes to

provide increased hot gas turbulence, increased furnace pressure and improved flue outlet temperature control.

5. All tubes shall be exposed to radiant luminous heat in the boiler furnace to create high water flow

rates at all loads and substantially increase heat transfer in the convection zones outside the furnace.

6. Boiler tubes shall be SA 178 Grade A and shall be no less than 1 ½” dia., .095 wall thickness,

made of only domestic U.S. steel and shall be easily removed and replaced if necessary without need for any welding or rolling. Tubes directly beneath the flue gas outlet shall be easily removable without the need to disconnect, move or modify the flue outlet cover arrangement or raise / remove any part of the boiler roof panels. There shall no more than one (1) 180 deg. bend in any single boiler tube. All tube bends shall be made with a mandrel type industrial bender to insure maximum I.D. opening at each bend.

7. Boiler vessel design shall insure that total boiler tube lengths shall be equal on each side of the

vessel to maintain balanced flow through boiler.

8. A large down comer shall be located external to the boiler housing. This down comer shall provide natural internal circulation without requiring external pumping sources. Down comers located within the boiler housing shall not be acceptable.


9. Boiler shall have an air vent connection located at the highest point of the vessel and one (1) hand

hole type inspection opening at each end of each drum with yolk type covers. Threaded pipe type openings will not be accepted. Lower drum shall have a 90 deg. threaded drain opening at the rear of the vessel at the lowest point as standard.

10. The furnace heat release shall not exceed 45,000 BTU/hr per square foot of heating surface

exposed directly to the radiant flame. For boilers with heat releases greater than 45 000 BTU/hr per square foot of heating surface, then a minimum of 5 square feet of total heating surface per boiler horsepower shall be required. The furnace volumetric heat release shall not exceed 67,000 BTU/hr per cubic foot of furnace volume.

D. Housing and Jacket Construction:

1. The boiler base shall be constructed of heavy gauge steel. Base shall be poured with one layer of

1900 deg. F insulating refractory to cover all base plate steel contact points. An additional 2 inch layer of 2700 deg.F castable refractory shall then be poured covering the insulating refractory. The high temperature refractory shall have no contact points with the boiler base steel. Boiler bases insulated with mineral fiber wool type insulation shall not be acceptable.
