DESCRIPTION COST 2. SIlica Analyzer necessary for measuring demIneralIzer $9,000 performance and quality of water beIng fed to bOIlers. SilIca In steam gOIng to turbInes will cause serious damage to blades. 3. 011 Analyzer (laboratory) used for detectIng orgamcs $8,000 breakthrough from makeup water treatment carbon filters before demineralizers. Hydrocarbon contamInatIon of demIneralIzer resins can cause irreparable damage and reduction of capacIty reqUIred for boiler feedwater makeup. 4. Dissolved Oxygen Probes (feedwater) a speCIfic IOn $26,400 oxygen probe analyzer is needed for contInUOUS monitoring for control of dIssolved oxygen In feedwater to each boiler between 50-250 ppb. ($2,200 each x <strong>12</strong>). 5. Oxygen Analyzer (laboratory) as a lower cost alternate $2,500 to onlIne monitoring, a modern portable oxygen analyzer can be used manually to obtaIn faster and more accurate readIngs than present. 6. Conductivity and pH Meter (laboratory) used for testing $1,000 water quality at water treatment, feedwater and condensate systems. 7. Level Gauges for Four Mazut Tanks Important for $10,000 measunng deliveries and consumptIon of fuel. 8. CalIbratIOn Gases and MaIntenance for Zeigler CEM $6,000 on No.3 Stack for measunng emissions from Umts 1, 4, 9, 10, 11, <strong>12</strong> 9. Distributed Control System for Reconstructed Umt $350,000 required for upgrading and automatIng combustIOn control system to comply with regulations for flame safety, as well as improvement of combustIon effiCIency as a result of automatIc control of fan dampers for combustiOn aIr and control valves for fuel to meet load. More rapid response to load changes WIll result In stable and effiCIent combustIOn whIch help lower maIntenance costs. 10. Water Treatment Resins for DemineralIzers Required $1,500,000 for making high quality makeup water for boilers to prevent damage, as well as to minimize chemical consumptIOn and discharge of regenerant waste. 5906-01/02A/BURSHTYN/5f17/95 17
5.3 Replicatine and Expandine the Proeram to Other Power Plants An economic benefit can be derived from extending the demonstratIon program to other Ukrainian Power Plants. From Burns and Roe expenence the UkraInian Power Plants, when firing coal or coal and mazut, exhIbIt the following typIcal charactenstIcs: • Ukrainian power plants operate In a steady-state mode (base load),with a turbine maintaining throttle pressure, "fixed" finng rate, floatIng frequency and manually adjusted aIr flow (fixed settings for each load). • Very hIgh in-leakage rates (up to 100%) are typical, WhICh make readings of any oxygen analyzer dependent on its locatIOn (dIstance from the furnace). They also make impossible on-line calculation of the combustIOn efficiency at the back end of the boiler. What IS calculated by the Enerac IS boiler effiCIency. • Most of the oxygen analyzers are of the extractIve/paramagnetic type, WIth questIonable accuracy and a measurement tIme constant on the order of about 1-2 mInutes. As a result, they cannot be used for real tIme excess air control. • Low carbon monoxIde levels (10 to 100 ppm) In the flue gas In combmation with 4 to 5 % oxygen In locatIOns WIth 850-870 Degree CentIgrade temperature leads us to believe that combustIOn effiCIency of the Ukraiman Power Plants can be improved. In our estImatIOn, the Improvement will be on the order of 0.5 % to 1%. The conclusions are as follows: • Excess aIr can be reduced untIl a maximum of 300-400 ppm of carbon monoxIde is generated whIch is indIcatIve of effiCIent coal combustIOn. • ConSIderable economic benefit can be realized by reducIng the excess oxygen by 1-1.25% and achieve 0.5 % Improvement In combustIOn effiCIency even WIth existIng manual control of the combustIOn process. It is Important that constant operator attention IS maIntained. Such attentIOn can be obtaIned by way of operator incentives based on the fuel saVIngs. Another alternatIve would be to invest in expensive automatic control for the excess air system. • Savings can be achIeved more easIly WIth carbon monOXIde measurements of the undIluted flue gas at different boIler loads • Improvements In boIler effiCIencIes and reductIons In fuel consumptIOn can be further demonstrated by replIcating and expandIng the portable combustIon analyzer program to other UkraInian power plants. 5906-01/02AfBURSHTYNI51l7/95 18
