[Q&A Question No. 075] Why is it necessary to maintain a certain negative pressure inside the heating furnace? 2017.03.16 The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Therefore, when fuel burns, a certain amount of air is required. In our furnaces, the air needed for combustion is drawn in naturally due to a certain negative pressure inside the furnace chamber. If this negative pressure is low, less air is drawn in, resulting in incomplete combustion of the fuel, low thermal efficiency, black smoke emission, a dim interior of the furnace, and even flames shooting out, which can disrupt the proper operation of the system. Therefore, a certain negative pressure must be maintained inside the heating furnace. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Third Round of Haichuan Outstanding Management Members Selection Contest http://bbs.hcbbs.com/thread-1655902-1-1.html (Source: Haichuan Chemicals Forum)
Fuel needs a certain amount of air to burn; only by maintaining a certain negative pressure, with the pressure inside the furnace being lower than that outside, can air from outside the furnace enter it
Prevents tempering and facilitates air intake
Fuel needs a certain amount of air to burn; only by maintaining a certain negative pressure, with the pressure inside the furnace being lower than that outside, can air from outside the furnace enter it. If the negative pressure inside the furnace is very low, the amount of air drawn in is minimal, resulting in incomplete combustion of the fuel. This leads to a decrease in the furnace’s thermal efficiency, black smoke being emitted from the chimney, a dim interior of the furnace, and even flames shooting out, which can disrupt the proper operation of the system

This is because a certain amount of air is required for fuel combustion, and the air needed for combustion in our furnace is drawn in naturally due to the negative pressure existing inside the furnace chamber. If this negative pressure is low, less air will be drawn in, resulting in incomplete combustion of the fuel within the furnace, low thermal efficiency, black smoke emission, a dim interior of the furnace chamber, and even flames shooting out, which can disrupt the proper operation of the system.
Fuel needs a certain amount of air to burn; only by maintaining a certain negative pressure, with the pressure inside the furnace being lower than that outside, can air from outside the furnace enter it. If the negative pressure inside the furnace is too low, the amount of air drawn in will be minimal, resulting in incomplete combustion of the fuel. This lowers the thermal efficiency of the furnace, causes black smoke to emerge from the chimney, reduces the brightness inside the furnace chamber, and in severe cases, even leads to flames escaping outward, disrupting the proper operation of the system.

Only by maintaining negative pressure can air enter the furnace and burn with the gas; otherwise, backfire will occur
