This post was last edited by Green Lotus on 2018-5-8 at 11:36. [Q&A Question 128] 2018.05.08: Explain why the pressure behind the furnace gas control valve is very high and the furnace temperature fails to rise How to handle it? Reason: ① Changes in the properties of the gas, with an increase in light components and a decrease in calorific value ; ② Flame arrester clogged ; ③The amount of raw material is increased too quickly, while the gas supply cannot keep up. Treatment: ① Continue to increase the amount of gas fed into the furnace, and contact relevant parties to ensure the composition of the gas ; ② Replace the secondary line cleaning flame arrester ; ③ Increase the raw material input slowly, raising the temperature first before increasing the amount of raw material. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ; Mass posting of posts – rated based on the lowest score ; Replies that are unrelated to the answer are considered spam and will be deleted immediately.

① The properties of the gas change: the light components increase and the calorific value decreases; ② Flame arrester clogged ; ③The amount of raw material is increased too quickly, while the gas supply cannot keep up. Treatment: ① Continue to increase the amount of gas fed into the furnace, and contact relevant parties to ensure the composition of the gas ; ② Replace the secondary line cleaning flame arrester ; ③ Bring in the raw materials slowly; ask questions first before specifying the quantity.

The nozzle is likely clogged; remove it and clean it.

The pressure behind the furnace gas control valve is very high; what is the reason why the furnace temperature cannot rise? How to handle it? Reason: 1. Changes in the properties of the gas, with an increase in light components and a decrease in calorific value ; 2. Fire arrester blockage ; 3. The amount of raw material being fed in is increased too quickly, while the gas supply cannot keep up. Treatment: 1. Continue to increase the amount of gas fed into the furnace, and contact relevant parties to ensure the composition of the gas ; 2. Replace the secondary line cleaning flame arrester ; 3. Increase the raw material input slowly, raising the temperature first before increasing the amount of raw material.

1. Nozzle blockage; Solution: Clear the burner; 2. The calorific value of the fuel gas is low ; Treatment: Adjust the composition of the fuel gas by adding components with a high calorific value ; 3. The burner has low efficiency and is not well-matched ; Solution: Replace the burner
