LSVR? Please attach the P&ID so we don't have to draw it out.

Currently p&id is not available.
I have doubts regarding the steam line and condensate line control system. As only steam trap would be controlling the steam inlet flow.

the globe valve on steam inlet with TI on oil outlet could provide a rough manual control in steady conditions...

I agree. The burners should operate well over a viscosity range. I once had a plant manager look over a proposed design and say: "Too much instrumentation. If I flew over this plant and dropped a wrench, it would hit an instrument!"

Steam line size us 3inch. If steam trap works fine , can there still be a chance of any steam blow off through oil heater?

Hi Mayank,
I agree with others keeping the control simple should be fine. I suspect the limiting heat transfer resistance is on the viscous oil side.
The steam side will not be limiting as long as the manual globe valve is set open enough for times when burners(s) are needing maximum fuel flow, and as long as the steam trap capacity (and condensate return system) can keep up with the condensate generation. The steam flow will therefore vary by itself just to match the heat taken by the oil.
The exchanger should also occasionally be cleaned on both sides of the heat transfer surface.
