Deposit Controllers (The Smart Controllers) are specifically designed to
control scale deposits, bacteria, corrosion, algae, and colloids in
boilers and industrial heating applications.
TWT Boiler/Heavy Industry System
The electronic deposit controller provides
continual scale control in the treated system, resulting in reduced maintenance and
more efficient operation (often yielding reduced energy
and water consumption).
What is the difference between
fire tube and water tube boilers?
There are two
basic types of boilers, fire tube and water tube. Fire tube boilers are
those commonly used in schools, hospitals, apartment buildings and commercial
buildings. As the phrase implies, there is a fire "in" the tube
and water is on the outside of the tube in a jacket that surrounds the
tube bundle. TWT offers both standalone components and fully
integrated standard systems to address these needs.
Water tube boilers are mainly
used for steam generation to develop electricity for distribution. This
type of boiler is about five stories high and water is "in" the tube.
These boilers are far more complex and have many sections to the system.
TWT products have been used for numerous applications with success.
Since the volume of water to be treated in these systems is
great, TWT recommends that you contact your TWT representative to help
design a custom system for your site.
How does a boiler work?
A fuel or energy source
at one end is drawn through (in) the tube, heating up the tube and
transferring its energy to the water surrounding the tube. The energy or
fuel medium may vary,
but the concept is the same - take this energy and pump it to equipment
that is designed to use the generated heat, e.g., heat exchangers,
radiators, convectors, coils, eductors, etc.
How do TWT Deposit Control
Systems help this process?
Thermal dynamics are greatly
inhibited when insulating deposits accumulate on the walls of the tube next
to the heat source (fire tube). This scale becomes a very costly problem,
as widely acknowledged by industry experts, government research officials,
and industrial managers worldwide .
For every 1-1/32th inch of scale, the process unit will experience a 10% loss of
efficiency (see the Federal Technology Alert - Energy,
referenced above. The TWT Boiler and Heavy Industry Deposit Control System
has the unique ability to clean and maintain an boiler system, while keeping the
particulates in the water in suspension. Most of these solids
accumulate in the belly of the boiler where they are "blown"
down periodically to eliminate them from the water chemistry. The
associated equipment is vulnerable to thermal dynamics loss. The TWT
Boiler and Heavy Industry Deposit Control System will keep this associated
blowdown equipment in top operating condition as well.
Engineers design a scale loading
factor when considering the needs of heat exchange by a factor of up to
25% loss. When equipment performance falls off in production rate, it
is an indication that it is time to clean out the scale and deposits that
have built up. Chemical treatment has been a traditional means of
maintenance for this condition, but such treatment requires down time for
the system, as well as exposure to chemicals and handling safety
issues. This means of maintenance carries a high cost in terms of
recurring chemicals purchases, proper storage and disposal measures,
OSHA compliance, environmental and health repercussions, and also leads to
unnecessary wear on equipment and shortened equipment lifecycle.
Chemicals can erode nearly any surface, at various rates, depending on base materials
TWT Deposit Control Systems
offer advanced, safe, non-chemical technology to minimize or eliminate
such risks, while providing substantial hard and soft dollar savings,
and an environmentally responsible treatment alternative with comparable or
better results. Among the many advantages and benefits:
- Simple installation,
significant maintenance reductions
- Low capital investment and
initial costs, no recurring costs
efficiency and reduced operating costs (energy, water, and sewer
- High levels of production capacity for performance gains
- Extended life of capital equipment
(equipment lifecycle savings)
- Elimination of chemical costs
and exposure (other than oxygen scavengers)
- Lower total KW usage due to less
friction / stricture (now under mandate in some localities)
- Man/hour maintenance to production ratio lessened
- Environmental impact
significantly reduced or eliminated
- TWT equipment easily
deinstalled and relocated, when desired
- Seals, gaskets, shafts,
impellers, volutes, metering valves, sensors, monitoring
equipment, orifices, capillaries, etc., will experience lower maintenance, longer life,
and better operating control.
It is important to note:
We have one exception to the
non-chemical concept of TWT Deposit Control treatment. Oxygen
scavenger use in
boilers is very important, and should be continued, even when treating the
boiler with a TWT Deposit Control System. This additive absorbs the oxygen
that might produce iron oxide or ferric acid. Such a condition could "eat"
the base material, causing failure. We cannot eliminate this ingredient in
the total boiler treatment. The use of strainers, filters, screens must be
carefully designed so as not to produce a constriction or starving
How does TWT Deposit Control
The use of Triangular Wave
Technologies products maintains the heat transfer ability is at peak
operating conditions at all times, enabling the boiler to perform to
its highest level of original design. The result is the optimum amount of
energy input for the greatest return in production of heat transfer.
How does the TWT Deposit
Control System affect the
- Since TWT Deposit Control is a non-chemical treatment, there is no impact on sewer or
- Since the process equipment will be
operating at high efficiency, there will be reduced emissions of Sox and
Nox, and the electro-static precips will require less maintenance.
- Since TWT Deposit Control Systems are chemical- free, there will be far less storage and
handling of hazardous materials, and less paperwork required.
