LOW NOx HIGH EFFICIENCY PREMIX BURNER

DIRECT FIRED HOT WATER BOILER

Bent Steel Water Tube Parker “LR” Model

Premix Gas Fi r e d

THE PARKER DESIGN

A time proven product backed by one
of the largest and most successful
Manufacturers of Packaged boilers
whose name is synonymous with quali­ty and safety. Every boiler is thorough­ly factory fire tested and is required
to meet the highest standards in all
phases of mechanical and operating
efficiency before shipment.

Parker Hot Water Boilers are
designed specifically to provide the
building heating and industrial pro­cessing industries with a Superior
Quality Boiler with Unequaled
Advantages in Safety, Long Life
Service and Economical Operation.

BENT TUBE CONSTRUCTION

The Parker Bent Tube All-Welded
construction is the most flexible
and durable on the market.

ADVANTAGES

1. Low NOx

The burner system will meet most Best
Available Control Technology Require­ments that exist now. The system has
the ability to be adjusted to extremely
Low NOx emissions.

2. High Efficiency

These High Efficiency “LR” models
incorporate a built in finned steel tube
bundle in addition to the standard
tubes. These heavy duty finned tubes
a re placed above the standard Parker
tubes, and they significantly incre a s e
the amount of heat absorbed from
the flue gases, thus increasing boiler
e ff i c i e n c y.

With the additional heating surf a c e ,
the already long Parker Hot Wa t e r
Boiler life is extended even furt h e r.
The efficiency ranges from 83 to 85%.

3. Safety

Our ASME tube bundle is extre m e l y
flexible and offers a long life with a 20
year warranty against thermal shock.
No Parker Boiler has ever been known
to experience an internal explosion.

4. Heavy Welded Flexible
Tube Construction

The Parker steel tube bundle is 15/16”
OD (.133”) thick, and the finned tubes
a re minimum 1” OD (.11”), heavy

thickness steel. This thickness is almost
double standard gauge boiler tubing for
the same diameter. The bent tube design
p e rmits free expansion and contraction
of each tube independently with changes
in temperatures, eliminating strain on
the metal, warping and leaking, typical
of rigid straight tube designs. This con­s t ruction utilizes heavy material with
flexibility to provide extreme safety
and long life.

5. Codes

All Parker Direct Fired Boilers are manu­f a c t u red in accordance with the ASME
Power and Heating Boiler Codes and
re g i s t e red with the National Board
of Boiler and Pre s s u re Vessel Inspectors.

THE PARKER PREMIX
BURNER SYSTEM

The Parker Premix System consists

of a burner bed of Heavy Duty Metal

Fiber Burners (MFB). Through a gas/
air premix manifold, the burners may
be linked to a fully modulating blower
mixer which offers precise control of
combustion through the full range of

modulation.

BURNER SYSTEM ADVANTAGES

Durability and Testing

The Parker System offers an extremely
durable and field proven Low NOx
Premix Burner, with hundreds of suc­cessful field installations in harsh boiler
environments providing heat, day in
and day out. Extensive factory and
field testing has occurred.

Even Heat Distribution

Unlike Conventional Power Burner
Technology, the burner bed provides a
uniform heat distribution on all boiler
tubes for improved heat transfer and
boiler efficiency. Uniform heat over the
entire heating surface at high, low and
modulating firing rates provides longer
tube life by eliminating concentrated
firing on limited tube surface.

Low Maintenance,
Simple Adjustment

The simplicity of the System with no
FGR fan or valve, allows normal boiler
operators to adjust and service the
System. Allen screws provide simple
precise adjustments through a charac­terizable fuel valve. Filters are not
normally required. Combustion
repeatability is unsurpassed.

burners. The Heart of the

Low NOx Boiler.
