【Daily Question】Multiple-choice question 11.6 For oil processing, the specified furnace temperature for heating furnaces is ≯（not more than）（ ）°C. Answer: A. 800; B. 900; C. 1000
For oil processing, heating furnaces are required to have a furnace temperature of ≤ (not more than) (A) °C. A: 800; B: 900; C: 1000
The furnace is specified to have a chamber temperature of ≤ (not more than) (900)℃
800: Because when the furnace temperature is 800°C, the heat transfer through the radiant tubes is high, resulting in a high heat intensity; this makes it easy for the oil inside the tubes to coking. Additionally, the material used for the furnace tubes has limitations – it cannot withstand temperatures above 800°C – which makes the tubes prone to damage.
I’m not too sure about 800.
800℃ is generally kept at 800 degrees Celsius as the maximum value, but this is not absolute
Multiple-choice question 11.6 For oil processing, the furnace temperature specified for heating furnaces is ≯ (not more than) (A)℃
A, 800. --------------------------------------------------------------------
A 800; the temperature must not exceed this value.
