Natural gas thermal furnace
Thread Content
Everyone: My company has two heat-conducting furnace boilers (which are made of natural gas). Now when they are running, a lot of water is discharged from the lower outlet of the flue. The outlet temperature also feels very low. Please tell me what is the cause?
This post was last edited by zdl1966 on 2018-1-13 11:37 What is the water content of natural gas? Or is the exhaust temperature too low?
Also I want to ask: How much does it cost to use natural gas compared to coal?
The exhaust gas temperature used to be 170 and is now 135
The normal outlet temperature used to be 205 and is now 168
When natural gas is burned, there is water.
It is necessary to comprehensively analyze other parameters
Does natural gas contain too much water?
According to [the exhaust gas temperature used to be 170 and is now 135, the normal outlet temperature used to be 205 and is now 168] it can be judged that it is possible: 1. The composition of natural gas changes and the calorific value decreases. 2. If the air volume changes, check the excess oxygen content. The exhaust gas temperature dropped to 135°C, so the moisture produced after combustion was not completely vaporized, and part of the water vapor condensed.
