A petroleum stock at a rate of 1200 bbl/hr. of sp. gr. 0.8524 is passed through a train of heat exchangers and is allowed to enter directly the radiant section of box type heater at 220°C. The heater is designed to burn 3,500 kgs per hour of refinery off gases as fuel. The net heating value of fuel is 47.46X10³ K, per kg. The radiant section contains 150 sq. meters of projected area of one row of tubes (10.5 cm OD, 12 m long and spaced at 2 OD) Find the outlet temperature of the petroleum stock,

Question
Transcribed Image Text:A petroleum stack at a rate of 1200 bbl/hr. of sp. gr. 0.8524
is passed through a train of heat exchangers and is allowed to
enter directly the radiant section of box type heater at 220°C.
The heater is designed to burn 3,500 kgs per hour of refinery off
gases &s fuel. The net heating value of fuel is 47.46×10³ K,
per kg. The radiant section contains 150 sq. meters of projected
area of one row of tubes (10.5 cm OD, 12 m long and spaced
at 2 OD)
