Case Study of Baji Gas Station unit one and Three for Performance Determination

Abstract

Baiji thermal station supplied by heavy fuel HFO from Baiji refinery, while the gas station is operated by heavy fuel HFO and light fuel LFO, the first unit operates using LFO, the third unit operates using HFO. The results showed that the specific fuel consumption is reduced by rising the load, when the load is reduced to 20Mw s.f.c almost 0.765m3/Mw.hr this rate start to fall to become 0.35m3/Mw.hr when the unit operate near its maximum capacity for LFO, while the heavy fuel increases by 15% for the same number above. It’s correct that LFO is good but it is expensive which costs 1000$ per imported ton , in order to cover the load of 8000Mw for one year itcosts 1.92E+10$ for imported LFO ,9.6E+10$ for the local LFO, and 2.8E+9$ for HFO, the difference is obvious which is ten times the total cost. Also the studied performance of the gas units showed that the net is experience from a  downturn of frequency along 24hr except in the let hours at night, while the allowed frequency is 50HZ±1.5, and the true efficiency of the units is a function of the load which stabilized at 29%±0.2 for the first unit and 25% for the third unit, while the thermal efficiency is stabilized at48% for the first unit and 51% for the third, therefore the unit efficiency is improved by 4% when we use LFO. When in take in to account the pollution, the heavy fuel HFO contains 4.5% sulpher which releases sulpheric acid and 1% vanadium treated by adding inhibitor about 1.5L/Mw.hr, these ratio are not considered for LFO with respect to HFO.
