Water accumulation at the inlet of the exhaust fan
Thread Content
The heating furnace runs solely on gas; when the exhaust gas temperature is below 120 degrees, or during cold weather with heavy rain, water accumulates at the inlet section of the induced draft fan. If too much water accumulates, it leaks out through the flanges of the baffles. A solution is needed.
Add a drain valve at the lowest point of the inlet: lol
Agree with the view above: add a drain valve at a low position in the inlet section of the exhaust fan to drain water when it is present.
There is a drain valve, but the green water that comes out is difficult to handle, so it cannot be sent to the sewage treatment plant
Pour it directly into the valve well; it will end up at the wastewater treatment plant anyway.
The amount shouldn’t be that large; it can just be drained away:lol
It’s really hard to get a queue; environmental regulations are strict, and leaders are afraid of taking responsibility
Three or four barrels leaked, and even more would leak if it were discharged directly. On one hand, the wastewater is difficult to treat, and on the other hand, water keeps flowing continuously, so discharging it isn’t a viable solution. The current approach is to raise the temperature and evaporate it, which means sacrificing furnace efficiency. What needs to be found now is the reason for the presence of water? A better way?
When the hydrogen component burns, water is produced; moreover, the moisture content in the primary and secondary air of the heating furnace must also be taken into account； Water condensation can also cause dew point corrosion; in cold weather, it is appropriate to increase the temperature of the flue gas, or consider raising the heat exchange temperature in the waste heat recovery section so that the heating medium is not too cold
How many stages does the air preheater in your unit have? Is it a metal corrugated plate type, a heat pipe type, or a glass plate type? In any case, sedimentation usually occurs at the lowest points. If there is concern that the acidic water will not meet environmental standards, neutralization facilities for collecting wastewater can be added; the water can be neutralized with alkali solutions until it meets the standards before being discharged.
The pursuit of thermal efficiency has now reached an unreasonable level, and in many cases it yields more harm than good.
