Suggested Specification
Furnish and install
as shown on drawings. A Penn (CROSSOVER Flash Separator &
Plate and Frame) or (Flash Separator Shell & Tube) Continuous
Blowdown Heat Recovery System as manufactured by Penn Separator
Corp., Brookville, PA.
The System shall
provide 90%-95% heat recovery from __________ #/HR. continuous
blowdown and shall have a make-up water capacity of __________
gpm. for boiler or boilers operating at a pressure/pressures
of __________ psig. flashing to a low pressure deaerator,
feedwater heater, or other low pressure steam use at __________
psig.
The Heat Recovery
System shall consist of the following components and accessories:
- Vertical ASME
Code Sec VIII, Div. 1 Stamped Flash Separator with connections
for tangential inlet with stainless steel wear plate, blowdown
overflow type drain, centrally located steam vent to provide
a minimum 97% quality steam, and tank clean out connections
as well as couplings as required for accessories.
- Heat Exchanger:
(A)
Plate & Frame heat exchanger ASME Code rated with parallel
herringbone stainless steel plates held together by zinc
plated bolts on EPDM ethylene propylene tapered gaskets.
The flow shall enter the heat exchanger through threaded
stainless steel connections in opposite directions to provide
U values of 3 to 5 times that of conventional heat exchanger.
The heat exchanger shall be located on the skid to facilitate
cleaning and maintenance.
OR
(B)
Shell & Tube "U" Tube type heat exchanger.
ASME Code rated with removable (stainless steel or copper)
tubes 20 B.W. G., cast iron head, and steel tube sheet.
Make-up to enter the head and tubes through NPT connections.
The blowdown connections NPT are located on the shell. The
heat exchanger shall be located on the skid to facilitate
cleaning and maintenance.
- Externally mounted
caged pneumatic level controller with stainless steel float
and control valve which maintain the water level in the
tank and heat exchanger. A level gauge shall be included
to visually monitor this level.
- Stainless steel
gauge panel with three remote thermometers showing temperatures
of the makeup inlet, make-up outlet, and blowdown water
to drain.
- A safety relief
valve will be provided to limit the systems maximum pressure
to protect the components of the system.
- Clean-out valve
located on the bottom of the flash separator and level control
piping, provided for periodic cleaning of the flash separator.
- Optional accessories
can include a multiboiler manifold A23M for __________ (No.)
of Boilers, a high level or low level alarm switch, pressure
gauge, and sample cooler with isolation valves and piping.
The flash separator,
heat exchanger, components and accessories shall be assembled
on a channel frame in a manner, which allows gravity drainage
of the blowdown through the system and to allow easy installation
and maintenance. The entire assembled system shall then receive
a coat of blue enamel paint and be packaged in a crate for
shipment. |
