Hello guyz,

I am new to this forum. We are ask by our company to create a project for improvement of our coal fired power plant.

Our group decided to submit a proposal that would modify the lubricating system of the turbine generator. Our modification would be to add a gravity feed oil tank to the lubricating system. The current system consists only 3 oil pumps namely, shaft driven main oil pump, auxiliary oil pump, emergency oil pump.

I just want to ask if what is the additional cost in adding the gravity oil feed pump? The advantages and disadvantages of this modification?? thanks..

Hello, what size oil tank will you need for this system? Also how much pressure are you operating at?

Hi..
Generally, it has two different ways for fuel transfer for areoplane, the simplest one is by gravity, and another is by pumps. But the simplest one mighte change to the vital method in some situation, such as electrical and mechanical accident. So the study of gravity feed oil is aslo important. Past calculations assumed that, under gravity feed, only one fuel tank in aircraft supplies the fuel needed for preventing extremely serious accident to happen. Actually, gravity feed oil is a transient process, all fuel tanks compete for supplying oil and there must have several fuel tanks offering oil simultaneously. The key problems to calculate gravity feed oil are the sumulation of the multiple-branch and transient process.

Hello people, how are you ?

I work at steam power plant , Turbine system is from {MHI} Mitsubishi Inc. , the lubricating system for the turbine rotor is consists of ( main oil pump , Auxiliary oil pump , and Emergency oil pump } that is the describtion of our system. the oil supply tank is at zero level.

if you put the gravity line , it will be more reliable to operate under any circumstances of lube oil pumps .
we call it the last protection line of lubricating oil system.

did you finish the project? can you give an idea about budget? we had a severe damage in our steam turbine after a black out and are interested in this project...thanks...

Dear All,

I am working in 2*150 MW steam turbine (reheat cycle based) power plant commissioning and after that operation - turbine side

We have gravity filled oil tank supplied by our turbine supplier company
its a great advantage of gravity filled oil tank at the time of power black out when all pumps MOP, AOP, EOP and its elevation should be 10 meters above the lube oil header so that it can provide approx 1 Kg/Cm2 pressure for turbine bearings.

Cost of this project in approx 2-3 Lacs (SS piping and Tank)

Thanks

Regards
