Reasons for off-flow in a double-tube heating furnace
Thread Content
To get things started, I’m using a double-tube heating furnace from a domestic brand in my installation, and I’ve encountered several instances of uneven flow. The first time it happened was due to the inlet distribution pipe being of the F-type, which caused uneven distribution of the flow; the second time, I changed the inlet distribution pipe to a T-type and added bypass manual valves. However, because the composition of the raw material was too light, the gasification rate inside the furnace was too high, resulting in uneven flow in the tubes. Later, by injecting steam at the inlet to increase the pressure there, the situation improved. Everyone, please share what kinds of abnormalities have occurred in the heating furnaces in your own installations, so we can learn from each other and improve our systems
