3.6.6.9
Fuel Burning Equipment Testing
a.
Test of fuel burning equipment shall demonstrate that equipment
installed will meet requirements of specifications, and that
overall efficiency is as specified, with not over 15 percent
excess air, can be obtained with boiler operating at 100 percent
floor, baffle or watertube.
b.
Test shall include all boiler and burner interlocks, safety
interlocks, combustion controls, actuators, valves, controllers,
gauges, thermometers, pilot lights, switches, etc. prior to
combustion testing. All malfunctioning components shall be
replaced. Submit an itemized data record sheet of this component
testing.
c.
calibrated and set to ensure the specified performance. The fuel
burner, forced-draft fan, controls, etc. shall be fully
coordinated, manually capable, and automatically controllable to
hold the required settings. The boiler fuel burning system shall
be continuously variable throughout the specified operating range
without manual adjustment of burner, register or nozzle, and
turndown shall be achieved without manual adjustment. Testing
apparatus shall be set up, calibrated, tested and ready for use
prior to final combustion testing. Calibration certificates for
all test instruments shall be furnished with test data.
3.6.6.10
Deaerating Feedwater Heater Testing
Test of deaerating feedwater heater shall demonstrate that equipment
installed meets specified requirements as to performance, capacity, and
quality of effluent. During operating test of boiler, tests shall be
conducted to determine oxygen content in accordance with ASTM D 888, Method
A. Boilers shall be operated at varying loads, up to maximum heater
capacity, while oxygen tests are being made. Means and equipment shall be
furnished to perform this test.
3.6.6.11
Water Treatment Testing
Test of water treatment equipment shall meet requirements specified as to
capacity and quality of effluent. Tests for ion exchange units shall cover
at least 2 complete regenerations and capacity runs. Test for hot process or
other precipitation type softeners shall cover a minimum continuous period of
48 hours with samples being taken at 2 hour intervals.
3.6.6.12
Steam Quality Testing
Test for steam quality and water level stability shall be simultaneous
under operating conditions specified.
3.6.6.13
Water Level Stability Testing
Boiler water level stability shall be specified by boiler manufacturer in
writing to Contracting Officer prior to test. Test shall first be
conducted by use of manual bypass around feedwater regulator. Test shall
be repeated using automatic feedwater regulator. To be acceptable, boiler
shall maintain specified water level stability as specified by boiler
manufacturer under both conditions.
