Ring Main System & It's details:

To achieve complete combustion, it is necessary to get good atomization. For the oil pressure atomization, it depends upon oil viscosity and other properties of the fuel oil used. As discussed above, to get good atomization of the available FO, it is to be heated up to 130 Deg. C (for heavy oil, maximum viscosity in accordance with DIN 51603 is 450 mm 2/s or 450 cSt at a temperature of 50 Deg. C. From the graph, which shows the viscosity

  • it can be seen that heavy fuel oil S remains pumpable up to value of 500 to 750 mm2/s or cSt. Since you are using pressure jet, oil return type atomization burner system, viscosity needed is 15 to 20 cSt  at the nozzle tip and this can only be achieved by heating up to 130 Deg. C and heating type nozzle rod in burner.
  • From the above data it is necessary that furnace oil must be heated up to about 50 Deg. C, to make it pumpable, and to approx 130 Deg. C to allow pressure atomization. As explained above, to facilitate heating up to 130 Deg. C and to suppress the boiling point of water (100 Deg. C at one bar), the oil should be supplied at 46 Kg/ cm2 at the in let of fuel oil pump.
  • This will avoid the vaporization of water content in the oil and low boilers in the furnace oil and in turn safeguard the fuel pump from cavitation problem and ensure proper operation of the burner system.

Bulk Temperature And Film Temperature In Thermic Fluid Heating

Thermic fluid heaters and its working temperature is always a perplexing term and it is also mostly misunderstood expressions. Generally, all thermic fluid manufacturers recommend certain economic operating temperature or optimum fluid bulk temperature based on its useful life of the product. Hence, the manufacturer of Thermic Fluid Heaters recommends a continuous operating temperature of 300 °  degrees Centigrade for such a heater in their expectations or estimation of temperature profiles. But it is important to understand various aspects of temperature when thermic fluid flows through tubes of heater. When fluid flowing in the coils or tubes of the heater, a very thin layer of the fluid all along the metal periphery vehemently adheres to the solid metal very strongly. This layer never moves and form a film or layer which is a stationary oil film. This film creates very high resistance to heat flow from outer heated metal surface to circulating thermic fluid. This resistance depends
