Why won’t the heating furnace start?
Thread Content
The main components of the fuel gas supplied to the heating furnace are 36% H2 and 62% CO. Why does backfire occur during combustion, and why is the flame not burning continuously with a popping sound? Is it due to an incorrect selection of the burner, or are the components of this fuel gas not suitable for combustion?
What burner have you chosen? In such cases, it is best not to use premixed and semi-premixed burners
There is no problem with the fuel; the issues and suggestions for resolution are as follows: 1. There is a problem with the selection of the burner. You can consult Luoyang Ruichang (the technical staff from Sinopec Luoyang Engineering Company) for advice ； ⒉The pressure is unstable; efforts should be made to stabilize it ； ⒊There is no flame arrester in front of the burner; a flame arrester should be installed
Our company also has a set of heating furnaces that exhibit this phenomenon; we believe the noise is caused by secondary combustion, so we increase ventilation to reduce the hydrogen content.
It might be due to unstable pressure; add a pressure regulator~!
We’ve encountered a similar issue with one of our furnaces as well; it could be a problem with the fuel valve, or the flame detector may be faulty or dirty, and most likely it’s due to incorrect adjustment of the burner.
There are serious issues with the burner selection; this type of gas should not be premixed, as this can easily lead to backflow, and a flame arrester must be installed on the pipes
