Proven technology to improve heater performance
(OP)
If any body who knows new proven technology to improve heater(especially fuel oil burning heater)performance without significant investment, please inform me.
In addition to this, if there is any good web site explaining energy saving tech. also, please inform me.

RE: Proven technology to improve heater performance
Calculate heat balances across your heater, check for heat losses and refractory efficiency, optimize excess air, steam atomization, draft and check for process eficiency.
Big investments appear after all these items checked, re-checked.
Normally, evrything starts with Q=m.cp.dt or Q= m.dH

RE: Proven technology to improve heater performance
What Andre has said is the basic requirement before you look at any other thing. A few things to be looked at are:
1.Reduce excess air, heat losses, leaks and clean-up your
convection tubes ( by soot blowing regularly).
2.Change to Low excess air burners
3. Additional Convection heat recovery by steam generation,etc. OR lower process feed inlet temperature
4. Air preheaters ( You need Forced Draft for this)
5. Check in all cases, you do not exceed heat flux allowed in the radiant section. Sometimes increasing excess air in burners shifts heat balance from radiation to convection and may improve efficiency.
