The Williams & Davis 2000D fortifies oureverlasting reputation for building the mostrugged and serviceable scotch marine boilerin the industry. The 2000D further offers ahigh efficiency design built to maximize fluegas velocities and transfer as much heatenergy as possible to the process waterinstead of exhausting it through the stack orradiating heat into the boiler room. Throughstringent and methodical building practicesperfected over almost 90 years in theindustry,Williams & Davis guarantees each of ourboilers will meet, and typically exceed, everyASME standard. All units are operationallytested and shipped as an integrated packagewhen practical, ready for quick connection toutilities. As such, we demonstrate ourconfidence in our boilers by offering theindustry's best pressure vessel warranty of10 years (25 year available) with anapproved water testing and treatmentprogram.(Shown w/ Powerflame Nova Plus Burner)Stainless Steel Jacket Available 2Pass Dry-backLow Radiant Heat LossesHigh Gas VelocitiesHigh EfficiencySpace Saving Design
Flanged Exhaust StackAll 2000D boilers are equipped with a vertical flanged exhauststack and are supplied with a matching installation flange.Flanges ease vent positioning during installation and providemore reliable exhaust seals during operation.BurnerBurners are available to operate with natural gas, a variety offuel oils, or a combination of gas and oil. NOx output levelsmay be specified as low as sub 7 PPM when burning naturalgas and 70 PPM for burning #2 fuel oil when the fuel-boundnitrogen is at 0.02% or less. Control cabinet is typically mountedto the front of the burner. Side mounting or remote boiler roommounting is available upon request.Safety Relief ValvesWide hex on valve nozzle provides wrenching service clearancefor easy installation and maintenance. Dual control rings offereasy adjustability for precise opening with minimum pre-open orsimmer and exact blow-down control.Tubes & TurbulatorsAll fire tubes are industry standard 2.5” outside diameter and0.109" typ. wall thickness. The fire tubes are inserted withuniquely-shaped corrosion resistant alloy steel Turbulatorsdesigned to break up laminar flow and maximize heat transfer.Pressure ControllerStandard Honeywell P7810 Pressuretrol provides solid stateautomatic operating control, automatic limit protection, manualreset limit protection, and 4-20ma modulating firing rate controlfor pressure systems up to 300 psi. Other pressure andtemperature controllers are available upon request.Structural SkidThe 2000D's rugged structural steel skid provides stability duringtransport and installation. Wide beam flanges distribute weightevenly across the boiler room floor during flooded operation.Low Water ControlsMcDonnell Miller 157S float level system provides reliablefeedwater pump control and primary low-level shut down. Probetype sensor and Warrick relay are used for reliable secondaryshutdown and to provide code-required manual reset. 2010, Williams & Davis Boilers. All rights reservedE1001-03
(Shown w/ Powerflame Nova Plus Burner)2000D Heating PassesFirst Pass - The burner fires at the entrance of thefurnace, transferring up to 70% of the available heatenergy into the water.Second Pass From the refractory-backed turnaroundchamber, flue gas is directed vertically into the top rowsof submerged tubes, travels across the length of thepressure vessel, and exits the system through the exhauststack. 2010, Williams & Davis Boilers.
