Hi,
I wan to transfer hot air into liquid tank and powder tank and want to know if air compressor can do the job or not? the compressor will be used to transfer hot air in a pressure way. It won't store hot air.

You have not supplied enough information to give you a reasonable answer.

Hi,
I want to push hot air in a liquid and want to know if I can air compressor to transfer hot air from a fir room to the liquid. The compressor should compress the hot air then push it into the liquid. are their special type of hot air compressors? can I use the regular one to do the job?

transfer hot air from a fir room to the liquid

Should I assume that "fir room" is intended to be a "fire room", like the boiler room of a power station?
- Some ideas for collection of CO₂ from a power station involve passing the exhaust gases through a solution which absorbs CO₂ (eg a sodium hydroxide solution).
- There are certainly concerns about the loss of efficiency that this imposes on the power station (so it produces even more CO₂!).

The first point is to say that the exhaust gases from a fire are extremely hot.
- Ceramics are one of the few materials that can withstand such temperatures and corrosive gases.
- Conventional air compressors use components like rubber gaskets and oil to lubricate bearings. These will rapidly fail if you use them to pump the products of combustion
- You would be more successful to use the air compressor to compress the cool air being fed into the fire, so the hot exhaust gas is also under pressure, and can be fed into the liquid.
- You should also note that the exhaust gas from a fire is well above the boiling temperature of water, so the water will quickly evaporate away unless it is kept under pressure and/or actively cooled.

...but I may have misinterpreted "fir" - maybe a sauna room was intended?

You might get a better answer if you ask the manufacturer of the compressor.

What are you trying to achieve?

What is the initial temperature of the air?  What is the flow rate you want?  What is the compressor air pressure you want?

I should explain why I need to push hot air in a liquid this will help me better to get the right answer. I am doing chemical treatment and mix 50% water with acid with 50% powder and to get the best result hot air (80-100) should penetrate through the mixture. How to get hot air forced into the liquid is the main concern.

[Bored chemist]

Is the air blowing bubbles in the liquid and maybe oxidising the powder?

If the air is going in through a pipe at the bottom of the container then a compressor should work.
But it is more efficient (and easier for the compressor) to compress the air from cold and then heat it before it reaches the liquid.
You would need some sort of heat exchanger to heat the compressed air.

Yes, the purpose of using hot air into the liquid to oxidize it and keep the liquide tempreture stable hot during the time of treatment. I like the idea of heat exchange after the compressor for effeciency.
