TYPE .005 DA-Ci-2t DEAERATING BOILER FEED UNITS WITH
DEAERATION DOME AWF PUMPS, AND A DIRECT INJECTION STEAM HEATING ASSEMBLY, AND A SHELL AND TUBE VENT CONDENSER
CAPACITY SCHEDULE MUST BE COMPLETED.
Furnish and install according to drawings and manufacturer’s instructions the quantity of .005 DA-CI-2T deaerating boiler feed units as shown on the drawings. Unit shall have a capacity of ____ pounds of steam per hour. The system shall be of the two tank design and guarantee oxygen removal to not more than .005 ccs/liter in the effluent throughout all load conditions between 5 and 100%. The deaerator shall be designed for atmospheric operation suitable for use with pumped and gravity returns. Pressurized designs are not acceptable. Each unit shall consist of (1) close grained cast iron receiver with a 20 year warranty against corrosion failure with a quantity of _____ boiler feed pumps, (1) direct injection steam heating assembly, (1) spray manifold in a deaeration dome with integral cascade trays, (1) modulating make-up assembly, electrical controls and accessories.
The boiler feed receiver shall be close grained cast iron, elevated to meet the NPSH requirements of the boiler feed pumps (with 2 ft. of safety factor). The receiver shall be supported by a structural steel frame and have a capacity as shown on the drawings. The boiler feed receiver shall be equipped with the following: (1) top and bottom shut-off water level gauge with automatic shut-off if glass is broken, (1) dial thermometer with separable well, (1) isolation valve between receiver and pump plus a valve in each bleed line installed for maintenance, (1) externally mounted high and low level alarm switches and low water cut-off switch. A suction isolation valve and an expansion coupling shall be installed in the suction piping between the receiver and the pump(s) to permit servicing the pump(s) without draining the receiver. The individual pump suction piping (manifolded suction lines not acceptable) must be sized for a velocity of 2.9 ft./sec. or less and contain no suction strainers. A liquid filled discharge pressure gauge with snubbers shall be provided for each pump.
All controls switches and valves to have a NEMA _____ rating.
A deaeration dome with integral 300 Series stainless steel cascade trays containing a spray manifold with stainless steel spray nozzles shall be flange mounted to the boiler feed receiver. The spray manifold shall be flange mounted to the dome. The flanged opening shall be large enough to permit the manifold to be easily withdrawn for servicing. A dial thermometer and a pressure gauge shall be an integral part of the manifold assembly.
A shell and tube vent condenser shall be installed on the deaeration dome to reduce the steam vent loss to trace amounts. The vent condenser shall preheat the incoming effluent to reduce the steam consumption of the main heating assembly.
A modulating water transfer assembly shall be installed on the DA chamber. The assembly shall consist of a controller, transmitter and valve with a three-valve manual bypass and wye strainer.The capacity of the transfer valve shall be equal to 100% of the load with a 10 PSIG drop across the valve. Transfer assembly will also send 4-20mAmp signals remotely as needed as well as alarms
A direct injection steam heating assembly shall be installed in the receiver. The heating assembly shall consist of a double flange mounted stainless steel injection pipe, steam control valve, temperature regulator, wye strainer and compound gauge for measuring vacuum or pressure gauge. The heating assembly shall be sized for the capacities as shown on the drawings.
The centrifugal boiler feed pumps shall be mounted on the receiver suction piping. The pump shall be (Horizontal or Vertical) a multi-stage cast iron construction with bronze wearing rings. The impeller(s) shall be Bronze for long life and durability. The pump shall be flexible coupled permanently aligned with a C-face motor connected to the bearing housing which is C-face connected to the pump. The bearing frame shall be designed with grease fittings for bearing lubrication. Bearings shall be extra heavy ball type with high temperature grease. The pump shall be fitted with a seal flush line designed to keep the seal cavity pressure at or below 50 psig. The pump suction flange shall be an ASA design. The pump discharge shall be also be an ASA flange design. The Silicon Carbide/ Viton seal shall be rated for 300°F service. The entire pump shall be dynamically balanced to deliver its full rated capacity with _____ feet of NPSH. The pump shall have a NEMA standard shaft. The horsepower and electrical characteristics shall be as shown on the drawings.
Each boiler feed pump will have a factory installed automatic flow control valve in the discharge of each pump.
Each continuously running boiler feed pump 71/2 Horsepower and larger will have a factory installed bypass line with a stainless steel orifice.
The manufacturer shall furnish a certified pump performance and NPSH test. The pump manufacturer shall furnish complete elementary and connection wiring diagrams and installation and operation instructions.
The entire pump package will be U.L. labeled when a control panel is furnished.
Electrical control specifications must be added. See electrical specifications for boiler feed pumps.
Specifications for the Surge Tank must also be included. You will use the specifications from the appropriate boiler feed section as your basis for the surge tank along with the corresponding electrical specifications and piping for continuous running pumps.
The Transfer pumps on the surge tank must run continuously and all make-up water must be introduced into the system through the Surge Tank—not deaerator. Transfer Pumps will pump all blended water in surge tank into the modulating transfer valve assembly located on the deaerator. An additional float switch will be located on the deaerator to automatically turn on the standby transfer pump in case of failure.  
Manufacturer shall be Shipco® PUMPS, P.O. Box 279, Shippensburg, PA 17257.
