3. Precautions and LimitationsBefore performing the procedure, ensure you understand the following precautions and limitations.

3.1 Precautions

3.1.1 Exposure to excessive negative or positive pressures can result in serious damage to the unit and auxiliary equipment. The following should be in service and operable prior to start-up for control of and protection against excessive furnace pressure or draft.

Furnace draft monitored constantly and automatically controlled to maintain -0.5 in. w.g.

Furnace pressure alarms set at +5.0 in. w.g. and -3.0 in. w.g. Master fuel trip (MFT) at furnace pressure values +8.0 in. w.g. and -8.0 in. w.g. Master fuel trip (MFT) and PA, SA fan trips at furnace pressure of +10 in. w.g. When starting a particular induced draft (ID), primary air (PA), and/or secondary air

(SA) fan(s) is to be started, the corresponding inlet control vanes and outlet isolating (shut-off) dampers (if supplied) should be closed. However, if there are multiple fans, the dampers (and vanes) on the companion idle fans should be open to assure that a clear air flow path (between ID, SA, or PA fan inlet and stack) exists when starting the fans.

[3.1.2] Care should be exercised to insure that proper fuel-air ratio for combustion is maintained. Operate Uunit should be operated with at least 30% excess air flow until 50% load. Operation Operating with less than the minimum expected excess air can be detrimental from the standpoint of combustion, emission performance, and safe operation of the unit.

[3.1.3] On commonly operated valves, such as superheater drains and vents, be careful to should be taken maintain the integrity of the root valves. These valves should never be in a throttled position, and it may be beneficial to leave them open and only close the end valves. The root valve would then only be closed for end valve maintenance or downstream line maintenance. Both valves on waterwall wall drains can be left closed. In all cases, end valves should be closed before closing root valves and opened only after opening the root valve in order to minimize potential root valve seat damage.

3.2 Limitations

[3.2.1] On a cold startup the rate of change in steam drum metal temperature (averaged) should be limited to not exceed 200°⁰F /hr.

[3.2.2] On a cold startup the rate of change in the saturated temperature measured at the boiler steam drum should be limited to 200°⁰F /hr.

DevDocs, 02/11/11,

Exercise care/Be careful to maintain proper fuel-air ratio for combustion.

of 104



Use: In-Hand

[3.2.3] On a cold startup the rate of change in combustion chamber exit gas temperature measured at the cyclone inlet should be limited to 200°⁰F /hr.

[3.2.4] The maximum allowable temperature differential between the top and bottom steam drum metal is 200°⁰F.

[3.2.5] Never add feedwater to an empty boiler steam drum if the drum metal to feedwater inlet to the drum temperature differential is greater than 200°⁰F.

[3.2.6] The baghouse hopper heater system (5A/B-QB-ME-512 thru 562) must be in service at least 10- to 12 hours prior to introducing any material or flue gas into the system.

[3.2.7] Using steam drum metal thermocouples to monitor steam drum metal temperatures, do not exceed a temperature differential of 200°⁰F of between top metal temperatures toand bottom metal temperatures at any time. This is primarily a consideration during either startup or cool-down of the boiler.

3.2.1[3.2.8] The unit can be operated up to the temperature limits indicated in the table below. To protect the equipment, the operator should correct any condition which has caused an alarm to sound.

[4.4.1] Always make sure that air flow tracks solid fuel flow when in either ManualMANUAL or Automatic control, to maintain a set excess O2 value (greater than 1.3 %).

4.3.1[4.4.2] Furnace and Emissions

4.3.1.1[4.4.2.1] Check SO2 emissions from the boiler.

Note Feeding limestone at greater rates than required will negatively impact NOx production and increase ash handling demands.

Adjust the limestone feed rate to maintain an SO2 emission level within permit limits.

[Note] NOx emissions are inherently low when the bed temperature operating range of 1450°⁰F to 1650°⁰F is maintained. NOx emissions increase as bed temperature increases.

4.3.1.2[4.4.2.2] Check NOx emissions from the boiler.

4.3.1.3[4.4.2.3] Verify proper fluidization of bed material and hot loop circulation by observing individual bed temperature thermocouples and flue gas temperatures throughout the hot loop, checking that temperatures are consistent within the hot loop.

4.3.1.4[4.4.2.4] Check the gas-side temperatures to monitor the cleanliness of the heat transfer surfaces.

4.3.1.7[4.4.2.7] Check the bottom ash removal system (stripper coolers) for proper operation.

Check the ash removal transport system for plugging periodically.

4.3.2[4.4.3] Water Chemistry and Steam Purity

[4.4.3.1] Strictly control of oxygen content and pH in the boiler water and feedwater must be done daily.

[Note] Always open the valve closest to the steam drum (root block valve) first and then close it last to reduce wear on the valve seats. These large valves should be opened slowly. When open, boiler inputs must increase to maintain steady-state conditions. Too much blowdown reduces boiler efficiency.

[Caution] Drain valves on the lower waterwall headers should not be used for blowdown purposes when the boiler is in operation. Improper use of these valves may interrupt waterwall circulation and cause tube failure due to metal overheating.

[4.4.3.2] Adjust the steam drum continuous blowdown valve in the continuous blowdown system when concentration of solids in boiler water is causing solids carry-over is being caused by excessive boiler water solids concentration.

4.3.3[4.4.4] Attemperation

4.3.3.1[4.4.4.1] Check main steam temperature and attemperation spray water flow.

Verify that desuperheating does not lower the steam temperature to within 20°⁰F of saturation temperature.

4.3.3.2[4.4.4.2] Verify a demand exists for attemperation (control of steam temperature).

4.3.4[4.4.5] Soot blowing

[4.4.5.1] Initiate a soot blowing cycle when economizer exit flue gas temperature increases becomes 30°⁰F above normal.

[4.4.5.2] Prior to operating the soot blowers,:

(a) Initiate a cleaning cycle on the baghouse and empty the fly ash hoppers. Soot blowing can overload the fly ash system.

DevDocs, 02/11/11,

Suggest: Keep the steam temperature at more than 20°F over saturation temperature.

DevDocs, 02/11/11,

Do not use drain valves on the lower waterwall headers to perform blowdown when the boiler is operating. Using these valves improperly may interrupt waterwall circulation and cause tube failure due to metal overheating.
