My friend, you already have pneumatic ash handling system for your boiler. Therefore, you are better equipped to describe all the settings. Just reverse engineer your system to get answers, to all your questions.

"seal use: sillicon" Anticipated temperature involved?

"is it neccessary to maintain the seal pressure more than conveying pressure?" What would be an anticipated consequence of seal pressure less than or equal to conveying pressure?

RTFM.

When you got your ash hauling system, there were operating instructions with it.

Dig those out of the trash and read them. Or, if the dog has already eaten them, call the manufacturer and ask for technical assistance.

We can't quite see the system from here.

Seal pressure is kept always more than conveying pressure and it is adequate in your system at 5.5 kg. You can reduce the conveying pressure up to 3 kg in steps. It will depend upon the process volume and convening line design. We are using 2.8 to 3 kg conveying pressure at our plant.

Get the design details of your conveying system. If the design capacity of your system is more than the actual quantity of fly ash generated, you can increase the cycle time in order to save compressed air.

Why ask us? Where are your Operating Instructions and Trouble-shooting? Why have you not asked the Supplier? Have you ever thought of emailing them instead us?

This is the problem. Many a times our new friends do not refer to manuals or ask the mfrs. of equipments. They simply post such questions which can not be answered.

I have noticed that people are posting these types of questions more and more often. I believe this is because many of them are finding themselves in a position to know without formal training or experience, and quite possibly missing manuals and records.

I imagine that these people are in rural areas or places trying to recover from some economic calamity or worse. To an engineer, the questions seem basic and uninformed. Under the circumstances of the OPs, I believe this view is correct.

However, If I were suddenly to find myself facing a failing local electrical plant with no help, manuals, records or engineers available to help me, and my need was to keep the plant running so that my local community could remain powered up, I would ask these uninformed questions here if I could, and I would pray someone would dispense with the formalities and just answer the questions.

These people are not stupid. They are probably desperate. Help them.

Right. Maybe we should ask him for the Operating Instructions read and then help him out.

"... If I were suddenly to find myself facing a failing local electrical plant with no help, manuals, records or engineers available to help me, and my need was to keep the plant running so that my local community could remain powered up..."

This sounds similar to a part of the plot line of the Stephen King novel The Stand. Has there been an unreported apocalyptic event?

LOL! It does. But really, we have no idea of the circumstances of these people.

And that's what makes me crazy. (It has also sent me to the naughty step more than once)

If these people would only offer the slightest bit of background to indicate that they really aren't just LAZY, OR INCOMPETENT I, and most others here, would be glad to help them.

I can certainly see the need for background! But when you are translating to English a technical problem you barely understand in your native language, well, it's got to be tough.

I saw a generator somewhere here in California that ran a Hotel for 100 years. There was nobody except who they could find to keep it running, and the maunfacturer was gone 50yrs, and the manuals lost to time and circumstance. I would have LOVED to do the maintenance on that thing! But I would be learning it fresh and new every step of the way. I learned from this history that similar setups exist in rural areas all over the place. The one I saw could have been in the mountains of India or BC, but here it was in California!
