In most plants, it would seem, machinery
must serve a double purpose. Not only must each machine
perform its job—it must do it with an unmelodic fanfare of
grinding and screeching and clattering.
|
 No man ever really grows used to the unnecessary noise of the
typical plant. He forgets it, at times, but the din is always
a drain on the nerves.
The mechanical equipment used to heat water and other liquids
through the introduction of steam into the liquid can produce
as much racket as any of its brother machines. It can if it’s
the old-fashioned heater... it can’t if it’s a Sims
HusHeater.

The HusHeater goes about its job without making a sound!
Moreover, the HusHeater operates completely free from the
destructive vibration that loosens rivets, opens seams and
damages instruments . . . thus adding to the life of the tank
and control equipment.
The most common application of the Sims HusHeater is in filter
boxes and hotwells, in both of which it will raise the
temperature of condensate to any desired degree (depending, of
course, on the amount of steam available and liquid
throughput). The HusHeater has also proven successful in
heating processes in sugar refineries, paper mills and other
plants.
Here are the advantages of the Sims HusHeater:
• Eliminates nerve shattering noise;
• Eliminates tank wrecking vibration;
• Conserves maximum amount of heat in the available steam;
• Efficiently heats liquids;
• Lessens burden on heater by reducing temperature difference
between feed-water discharge and heater exhaust;
• Reduces back pressure on auxiliaries, thus effecting a
saving of steam;
• Increases temperature of feed-water entering into the
boiler.
How to
install the HusHeater
Installation of the HusHeater is easily managed, but there are
certain precautions which should be taken to insure
trouble-free operation.
Your HusHeater comes to you assembled, ready to screw onto a
three-inch pipe. it can be fitted to odd sizes of piping by
means of reducers that step the pipe either up or down.
An important note: if the nuts on the HusHeater’s rod are
loosened for inspection, it is essential that they be
tightened to the point where the spring washer is entirely
fiat. There are no moving parts so there is no need to
disassemble for adjustments.
When used in an open feed system, the HusHeater may be
installed in any compartment of the filter box, but
performance will be better if it is located in the clear
filter water section. Sponges fail to do an efficient job in
removing oil and other contamination from hot water.
In setting the heater into any tank, the edge of the hood must
be submerged to obtain proper mixing of the heated liquid and
prevent surface noises. Complete submersion is better, but it
is important not to have the HusHeater rest on the bottom of
the tank. It should be suspended from the steam pipe or rigid
support and be completely clear of the tank base and walls.
There must be room for free circulation of the liquid under
and around the HusHeater.
The HusHeater is guaranteed to operate silently and
efficiently if properly installed. It can and will rumble
noisily if installed on the end of a gooseneck” (Fig. 43).
With correct piping, allowing for a downward flow of steam,
there will be neither noise nor vibration.
The Husfleater, as in the case of the Sims pump valve, can be
made of any suitable material to withstand service conditions.
For the most part, however, the efficient Sims pre-heater is
made of bronze.
Steam enters at the top of the HusHeater
and flows downward through the inside of the center
tube, black arrows; it traces an upward course on the
outside of the tube, where it passes through a series of
converging nozzles. Suction created by the high-velocity
flow of steam through the nozzles draws the liquid,
colored arrows, into the mixing chambers. The liquid is
heated to the desired temperature by the condensing
steam, after which it is discharge through the opening
under the hood of the HusHeater. Throughout, the
operation is silent and free from vibration.
How
to order HusHeaters
 The Engineering Department of the Sims
Pump Valve Company offers you full assistance in ordering
one or more HusHeaters for your plant.
As the first step in putting an end to your problems of
heating a liquid by the liberation of live steam into it,
send our engineers the necessary six points of information
concerning service conditions. Working from there, they
will be able to determine:
• the number of HusHeaters your operation requires;
• from what material they should be made.
While often one HusHeater is sufficient
to do the job, some operations have required three and even
four. Materials which are used in manufacturing these units to
meet specific conditions are: bronze, cast iron, aluminum,
stainless steel and others. Here
is the information our engineers will need to supply you with
a silent, vibration-free HusHeater:
a. Liquid to be heated;
b. Pressure and volume of steam available;
c. Dimensions of tank and normal liquid level;
d. Throughput of tank;
e. Normal inlet temperature;
f. Desired temperature. Case Histories
An electric control system was employed at
one plant to regulate the output and temperature of liquid
heated in a process tank. The original heater vibrated so much
that the delicate mechanism of the controls was upset. As a
result, specifications were rarely met. The vibration problem
ceased with the installation of a silent Sims HusHeater, and
from then on the electric controls were thoroughly reliable.
-
Coil heaters and jet heaters both
were tried in heating sugar liquor in a cylindrical tank at
a sugar refinery. With each type of heater, vibration was so
strong that even the steel supports of the tanks shuddered
visibly. Two 3-inch Sims HusHeaters were installed with
these results: no vibration, steady performance, practically
no operating noise.
-
A Sims HusHeater used in the filter
box of a steamship’s open feed system greatly improved
efficiency. The Chief Engineer wrote, "Using the Sims
HusHeater, I find we have a gain of 14 degrees in feed water
temperature, and a gain of 46 degrees in filter box, above
the best obtainable without use of the Sims Silent HusHeater.
The 230 degrees maximum temperature can easily be obtained
with a 5 to 6 pound less back-pressure using the HusHeater."
