valve train for #6 oil

valve train for #6 oil

valve train for #6 oil

(OP)
Hi,

Somebody have the suggested viscosity (SSU) at the oil valve train inlet of a thermal oxidizer?  A supplier told me to supply him 100 SSU at the inlet of the valve train. For my part, if i required 100 SSU at the burner, 100 SSU at the beginning of the valve train is too much

Thanks

RE: valve train for #6 oil

Are you useing its a fuel? If yes, then you will need some form of atomising media (steam is best). Most burner suppliers will quote a min. SSU of 200 at the burner in order to meet performance, if its lower than 200, then the oil should atomise easier, thus requiring less steam to atomise the oil.
If its pressure atomisation, then the lower the SSU the better will be the flame quality.
Confirm if its a primary fuel source of the incinerator.

We use bunker oil #6 with steam atomisation. We have a North american burner. The supplier ask us to get around 100 SSU at the burner. It's fine for us, but they also ask 100 SSU at the beginning of the valve train (before control valves, regulator, etc...) It seems that is too high for nothing. We need to rise up the oil to 260F

SCouture,

Heavy Oil is hard to burn - it is messy and difficult to work with if you do not have it all right.  The temp of the oil can vary a little but I suggest that you set it up get it burning cleanly and then try lowering the temperature.  At each interval record temperatures, flows, pressures etc.  If no smoke is present then try lowering the temp a little more.  

Note these conditions will change in the winter months if you have cold weather - heavy oil requires heat tracing and good insulation.  You do not want to be called, in the early morning hours to try and get one of these going in the cold weather!

Good Luck!

The viscosity at the oil gun is critical to its performance.  In some cases it is also critical at the start of the valve train in order to provide accurate metering of the oil through the control devices.  Check the viscosity requirements of your control valves and regulators, you may find that they specify a viscosity range for accuracy.
