30 thg 4, 2002 · If you have high dilution from the base metal, you may experience problems even with this, and could use type 310. The most difficult part is getting an accurate estimate of the correct percentages to plug in to the diagram.
11 thg 12, 2014 · I need your help! I'm an EE playing a ChemE. [sad] I'm trying to calculate the dilution factor of two gasses. I have a gas that is mixed with zero air using a timed valving scheme. Both the gas and zero air use a common flow rate(200ml/min). This is plumbed in such a way that the output of the...
15 thg 1, 2007 · First off natural draft then implies a draft hood, so you need primary/secondary/excess air for combustion and then you need dilution air to go up a draft hood. The 90% induced draft residential type of furncace will probably pull about 50% excess air through the heat exchanger along with the products of combustion and then blow it out the vent pipe. …
27 thg 7, 2006 · Here are some comments for your consideration: 1. Can you introduce nitrogen through a flexible hose through the inlet nozzle ? 2. Since the principle of 'safety first' governs, the best you could do is by trial. 3. By putting in 3.5 tank volumes you are already using a 'safety' factor of ~1.5 in your sweep-through purging scheme. The theoretical volume, Q, of pure …
2 thg 12, 2006 · During calculation to purge vessel to get H2S below 10% ppm ..... we found that we need five cycle to get our value, by nitrogen pumping.
