| OPERATION |
Gas jet blowers utilize
higher pressure motive fluids such as steam, air, or other gas
to entrain lower pressure steam, air, or gas. The motive fluid
passes through a custom designed nozzle. It exits the nozzle
at a high velocity as the pressure energy is converted to kinetic
energy. Momentum present in the motive fluid is transferred to
the suction fluid as the two fluids mix in the body of the blower.
The mixed gas enters the venturi tail section where the velocity
energy is converted to a disharge pressure intermediate to the
suction and motive pressures.
Gas jet blower performance is largely determined by the energy available
in the motive fluid. Actual performance depends on the operating conditions
of the particular application. Blowers are typically used in high volume,
low draft applications where a small volume of high pressure motive fluid
is used to move a large volume of low pressure gas. Higher compression
units are available, however. EST factory engineers are available to assist
in the sizing and application of gas jet blowers. See

| APPLICATION |
|
A gas jet blower
can be used wherever a higher pressure gas, air, or steam source
is available. The blower can be constructed in the standard
right angle ejector configuration or as an in?line unit as
shown. The in?line unit is ideal for installation into pipe
lines and dud work where small boosts in line pressure are
required. Some typical applications include venting fumes and
dust from grain silos, chimneys and ship bilges; feeding large
amounts of low pressure combustion air to furnaces; circulating
steam in steam aging cabinets and heaters; and gas blending
applications.
The chemical, pharmaceutical, petrochemical, pulp and paper,
and the power industries have all successfully utilized gas
jet blowers.

| CONSTRUCTION |
| The gas jet blower
is available in steel, stainless steel, Monel, Hastelloy, titanium,
fiberglass reinforced plastic, Teflon, and ceramic lined steel.
Smaller sizes are machined from bar while larger sizes are fabricated
from plate. Larger fabricated sizes can be coated with Teflon
or lined with rubber or other suitable materials. The internal
nozzle and tail diffuser are custom designed for the particular
application. Connections are typically threaded or flanged, but
special connections can be supplied. |
