DONNELLY ENGINEERING ELECTRICAL <br /> 5. Pitch horizontal runs of exhaust pipe away from the engine. Provide condensate traps with <br /> petcocks or valves at low spots in the exhaust system. <br /> 2.5 EXHAUST EMISSIONS <br /> A. General: To maintain environmental quality,the engine shall be equipped with a precombustion <br /> chamber compliant with EPA tier 3 emissions standards or have suitable emission control <br /> equipment to ensure that gaseous exhaust emissions do not exceed: <br /> NOx(Calculated as No2) 8.75 GRAMS/BHP-HR <br /> HC 0.25 GRAMS/BHP-HR <br /> CO 1.50 GRAMS/GHP-HR <br /> These maximum levels shall be at manufacturer's rated speed and load as measured by SAE <br /> J177 and SAE-J215 recommended practices. Verification of the ability to meet these emission <br /> specifications shall be available from the engine manufacturer. <br /> 2.6 GENERATOR <br /> A. General: Provide the following; <br /> 1. The generator shall be 3 phase,60 Hz, 1201208 volt,insulated, single-bearing,drip-proof, <br /> rotating field, synchronous type, with 1 phase brushless PMG exciter. <br /> 2. Provide Class H insulation limited to Class"B" (125 degrees C) rise. <br /> 3. Provide 100 percent epoxy varnish impregnation and a coat of epoxy asphalt insulating <br /> material to increase resistance to abrasive dust or sand, high humidity, and light acidic, oil, <br /> or salt-laden atmospheres, as well as prevent fungus growth. <br /> 4. Heaters for the generator must automatically deactivate when the engine starts in <br /> accordance with article 3-3.1 of NFPA 110. <br /> 5. Generator remote Annunciator must be battery powered from the generator batteries as <br /> required by NFPA 110 and NFPA 99 and the Florida Administrative Code. Utilize the existing <br /> raceway for both annunciators which shall be located at the 24 hour monitored Nurse station <br /> (where the existing Annunciator is located) <br /> B. SCR Equipment: Generator shall be designed for operation of SCR type equipment. <br /> C. Wave Form: The wave form deviation factor of the line-to-line voltage at no load and balanced <br /> rated load at 0.8 power factor not to exceed 4 percent. The rms of all harmonics shall be less than <br /> 2 percent and that of any one harmonic less than 1 percent at full rated load. TIF shall be under <br /> 50. <br /> D. Transient Dip: The transient dip shall not be greater than 20 percent of rated voltage when full <br /> load at rated power factor within 5 cycles is applied to the generator. <br /> E. Voltage Regulator: Provide a static type voltage regulator to maintain a constant and stable <br /> generator output voltage within plus or minus 0.5 percent of nominal for all steady-state loads from <br /> no load to full load with isochronous speed control and plus or minus 2 percent speed droop <br /> operation. A 5 percent variation in frequency and the effects of field heating will not affect the <br /> unit's regulation. Provide stability and voltage range adjustments. <br /> F. Fault Current: Provide permanent magnet generator boost to provide a minimum of 300 percent <br /> of fault current for 10 seconds. <br /> Heartland Health Care Center of Zephyrhills-3181 16650-7 DE No 217032 <br /> 38220 Henry Drive,Zephyrhills, FL 33542 Pending Emergency Rule 59A-4.1265 <br />
