Want To Know About Analysis Of Gas

There won't be any ash.

Smoke indicates insufficient oxygen at the burner.

PWSlack-

Since Ammonia only burns at high concentrations when mixed with air, what would be the effect of the other gases on the burning of the ammonia. Good, bad or indifferent?

Good Luck, Old Salt

Actually ammonia will combust as long as the other gases will support the flames, and ammonia should in fact help lower NOx emissions from the combustion.

You seem to know what analysis you need, you simply need to find a laboratory to do the work. Labs that deal with the petrochemical industry can provide these analyses. I would also get BTU content (and a bunch of other stuff), which are what is most important to you.

I believe you are referring to specific analyses, but the terms used (proximate analysis etc.) would only make sense to chemists, and I think they are not used often here in the US.

Contact a local fuels or petro. lab.

NH3 will have to be scrubbed out so with phenolics in water scrubber. H2 can be burnt but be careful of explosive mixture of H2 with Air. In certain range, mixture of H2:Air is explosive when ignited, numbers can be found out on net by surfing. You may earn Carbon $ also. But must involve a Consultant for proper design and feasibility of project.

I take it that this is a "waste" gas produced by some other process in your facility? As others have posted, 1. there should be no ash. 2. in order to obtain a "fuel" analysis you would need to obtain a sample which would probably be analyzed by a GC. There are various companies offering this service. They would obtain a sample of the gas and run the analysis.

If you already have a boiler or furnace where you could burn the gas as a "supplemental fuel" it would be a simple matter of obtaining the proper permitting and engineering a delivery/burner system to supply the gas to your existing plant. If you are thinking of building a specific boiler/furnace to burn it, you would have to obtain permits as a "new source" either as a waste incinerator or under your current permit.

Further, since H2 has such a high calorific value, you would want to do some flow / temperature modeling to determine the effect of burning the gas on your furnace temperatures. Go here: hydrogen.pnl.gov/cocoon/morf/hydrogen/site_specific/fuel_heating_calculator to get HHV and LHV of hydrogen by quantity.

Final products of combustion would depend on what else you are burning along with the waste gas. Just burning the waste gas though would produce CO2, CO, NOx, and water vapor, although since the Phenolics are only in trace amounts, there would be little CO2 or CO.

Several of you other posters mention NOx, apparently with the assumption that all ammonia combusts to NOx, and this is simply mistaken.

4NH₃ +3O₂ --> 2N₂ + 6H₂O is the primary combustion reaction for ammonia.

In fact, the presence of ammonia (that is used with NOx catalysts in HRSG's) will reduce overall NOx from combustion of the other gas components.

Not ragging on anyone in particular, wink, wink, nod, nod, but it is a mistake anyone could make if they do not have direct experience with ammonia combustion.

While this is true (I am aware of NH3 injection to reduce NOx) there still could be some NOx produced as there is thermal NOx to consider ... since ambient air is mainly N2, there is still the potential for NOx to be generated in this process. It would depend on the temperatures involved and proper air/fuel ratios.

I would consider this fuel mixture (as long as sufficient air is introduced) to give a really clean burn, since both hydrogen and ammonia would tend to reduce the NO_x to lower values than a hydrocarbon, or carbon burn. Cannot argue that there is no NO_x but I can make a pretty good argument for it being low enough for the OP to have a good outcome, provided they can get a permit issued for this.
