4. SURFACE BLOWDOWN SYSTEMS |
|
|
BLOWOFF
HEAT RECOVERY
Purpose: Recover waste heat from continuous boiler
surface blowdown by preheating boiler feed water before
it enters feedwater tank or DA. Units automatically control
blowdown rate to maintain desired level of dissolved solids
in boiler water and recover up to 90% of available heat
normally lost to drain.

FLASH
TANK HEAT RECOVERY
Purpose: Similar to the Blowdown Heat Recovery system
except for the addition of a ASME code flash tank to provide

CHEMICAL
FEED SYSTEMS
Purpose: provides means of injecting necessary chemicals
into the feedwater tank and/or boiler to control corrosive
gases and prevent scale formation in the boiler. Systems include
storage tank, pump(s), mixer, stand, and optional electrical
panel. Sizes: 50 to 200 gallons.

WATER
SOFTENER
Purpose: Soften boiler feed water by exchanging hardness
minerals (calcium and magnesium ions) with sodium ions forming
a soluble non-scaling mineral that will not build up on hot
surfaces. Softener systems include single or multiple resin
tanks, brine system, salt storage, and automatic regeneration
controls. Options include ASME tanks, special lining, skid
mounting, and special controls. Representing: Cleaver-Brooks

9. MECHANICAL DRAFT SYSTEM |
|
|
MECHANICAL
DRAFT SYSTEM
Purpose: Ensure boilers operate at maximum efficiency
by providing constant draft at all firing rates. System senses
draft and modulates fan speed as stack conditions or firing
rate change to maintain desired draft setting. System corrects
difficult venting arrangements, allows different category
appliances to be connected to a common stack and often reduces
vent size and stack height. Vent sizing is determined and
guaranteed by the manufacturer.

10. MECHANICAL COMBUSTION AIR SYSTEM |
|
|
MODULATING
COMBUSTION AIR SYSTEM
Purpose: Provide make-up combustion air to boiler room
to match burner requirements. System senses room air pressure
and modulates variable speed fan to match combustion air to
burner firing rate by maintaining a constant room pressure.
Replaces large combustion air louvers which often introduce
excess cold air into the boiler room.

maintains precise independent control of air and fuel throughout
the burner's operating range. It offers a high degree of accuracy
and dependability and will maintain optimum efficiencies.
Applications: Single or dual fuel with or without FGR.
Options: Oxygen trim, multiple boiler lead-lag control,
communications

15. WATER TREATMENT SYSTEMS
|
|
|
DEALKALIZER/DEMINERIALIZER
Purpose: Improve boiler feed water quality, reduce
boiler blowdown and reduce chemical usage. A chloride cycle
dealkalizer is an ion exchange process that contains a strong
base anion resin that is regenerated with salt brine and sodium
hydroxide which exchanges alkalinity, sulfates, nitrates,
carbon dioxide, and some silica for chloride ions. Dealkalizers
are recommended when the bicarbonate alkalinity exceeds 100
ppm, makeup exceeds 1,000 gallons per day and the chloride
count is below 120 PPM Demineralizer includes a strong acid
cation (regenerated with sulfuric or hydrochloric acid) unit
and strong basbase (sodium hydroxide) unit.

REVERSE
OSMOSIS
Purpose: Improve boiler feed water, reduce boiler blowdown
and reduce chemical usage. Uses a semi-permeable membrane
under pressure to reject dissolved salts and allow pure water
to pass through. RO is recommended for Food Processing, Sterilization,
or other applications requiring high purity water without
the use of water treatment chemicals.
