GENERAL DEMOLITION NOTES:WIRING LEGEND

A. DEAREATOR AND SURGE TANK SYSTEM SEQUENCE OF OPERATION:

1. DEAERATOR MAKE-UP WATER CONTROL VALVE:

THE MAKE-UP WATER CONTROL VALVE IS MODULATED BY WATER LEVEL CONTROLLER

AT DEAERATOR AS REQUIRED TO MAINTAIN THE WATER LEVEL OF THE DEAERATOR AT

SETPOINT.

2. DEAREATOR STEAM VALVE:

THE DEAREATOR STEAM VALVE IS OF THE SELF-CONTAINED TYPE. THE VALVE IS

MODULATED AS REQUIRED TO MAINTAIN THE FEEDWATER TEMPERATURE IN THE

DEAREATING SECTION OF THE DEAREATOR AT SETPOINT. THE BOILER FEEDWATER

TEMPERATURE. FEEDWATER FLOW, AND FEEDWATER PRESSURE ARE MONITORED AND

CONTROLLED BY DEAREATOR ADAC SYSTEM.

B. BOILER FEEDWATER PUMPS:

1. BOILER FEEDWATER PUMPS ARE AUTOMATICALLY STARTED AND STOPPED BY

DEAREATOR ADAC CONTROL SYSTEM AND MODULATE THE SPEED OF PUMPS TO

MAINTAIN THE PRESSURE SETPOINT IN FEEDWATER MAIN TO BOILERS.

C. BOILER ECONOMIZER SEQUENCE OF OPERATION:

1. THE BOILER TWO-STAGE ECONOMIZERS SHALL BE PROVIDED WITH ECONOMIZER

CONTROL SYSTEM (ECS).

2. THE SURGE TANK LEVEL CONTROLLER OPENS CONDENSATE VALVE TO DEAREATOR AS

THE LEVEL IN THE SURGE TANK RISES.

3. DEAREATOR LEVEL CONTROLLER SIGNALS MAKE-UP WATER VALVE TO MAINTAIN LEVEL IN

THE DEAREATOR,SENDING MAKE-UP WATER THROUGH THE SECOND STAGE ECONOMIZER

AND INTO DEAREATOR.

4. IF THE SECOND STAGE ECONOMIZER OUTLET WATER TEMPERATURE RISES ABOVE

ADJUSTABLE SETPOINT, THE ECS SHALL SIGNAL THE MAKE-UP WATER BYPASS VALVE TO

ADD MORE COLD MAKE-UP WATER, MODULATES THE VALVE ON THE SECOND STAGE

ECONOMIZER WATER OUTLET TO DEAREATOR TANK. THE OVERFLOW FROM THE

DEAREARTOR SHALL BE ROUTED TO SURGE TANK.

5. THE BOILERS SHALL BE FURNISHED WITH BOILER CONTROL SYSTEM. SEE SPECIFICATION

SECTION 15610. THE BOILER CONTROL SYSTEM SHALL SIGNAL THE MODULATING

FEEDWATER VALVE FROM WATER LEVEL CONTROLLER TO MAINTAIN WATER LEVEL AT

THE BOILER. THE BOILER CONTROL SYSTEM SHALL CONTROL THE SPEED OF

COMBUSTION BLOWER AND PARALLEL POSITIONING AND O/2 TRIM TO CONTROL THE

COMBUSTION FOR THE BOILER.

6. THE FEED WATER FROM DEAREATOR SHALL FLOW THROUGH FIRST STAGE OF THE

ECONOMIZER BEFORE GOING THROUGH THE BOILER.

7. THE SURFACE BLOWDOWN (SBD) AT THE BOILER SHALL BE CONTINUOUS THROUGH

NEEDLE VALVE (NORMALLY OPEN). THE SBD CONTROLLER SHALL SIGNAL THE CONTROL

VALVE AND AS THE TDS LEVEL RISES TO SETPOINT LEVEL, THE SBD CONTROLLER SHALL

SIGNAL THE CONTROL VALVE TO OPEN AND DRAIN BLOWDOWN THROUGH BLOWDOWN
