A little research on high pressure steam boilers, might give some insight as to why this might not be a good "home use system".
As i stated, the (heat/pressure/size) relationship is the point of great concerne.

A car have the same pressure and heat as a steam boiler and if handled wrong can explode and kill.
The thing is if it is possible to build a system with many smal chambers that you burn solid fuel in and is solid as todays engines, to be able to handle pressure safely.

The wood should burn much faster at higher pressure. What would be the point of this though? How would you quickly circulate the air at this high pressure. The system would require a high pressure, high air flow, pump for the air intake, and some type of pressure maintaining exhaust system. If the goal is just more heat, then just a fan to keep the air moving at a moderately fast flow will do the job, similar to a blast furnace.
The tube have all the air and solid fuel it need to create a high pressure and heat,
as in a normal engine but the fuel will burn much slower.
In the tube there can be a fan that can circulate the air as it burn.
The whole inside of the tube can be isolated so that the created exhaust gas heat can be contained in the gas while you let it out to a turbine after all the fuel have burned out.
In a normal engine the gas is directly in contact with the walls and the heat that is tranferes through the wall is cooled away and is a energy loss.
In this system you can isolate it and after the turbine taken the exhaust gas it can be loaded again if there are enough of other tubes that can be running while the temp of the tube is cooled and loaded up.
This could be an idea to gasoline engines maybe.
The whole gasoline engine could be isolated and more efficient if there were enough cylinders running while the cylinder cools down to a temp so the fuel don't self ignite when it later is loaded again when it is its turn.
Its a compleately crazy idea because the engine would need to many cylinders but i like my insane brain and maybe someone can make something of it. :)
But I guess the best idea to get a normal engine more efficient is to use a system called turbosteamer from BMW.

why don't you get a compressed air tank with those little air gun things and shoot air at the fire
if done at the right place i think it makes a bigger fire
You are a funny man. :)

As others stated, what you are thinking of trying is dangerous.
Beyond that, it won't do anything useful. In order to generate power, the air/exhaust needs to move through the turbine. You can't have a constant high pressure in some vessel and still have the air moving through a turbine.
I take a tube and put a solid fuel in it like wood and then i fill the tube with compressed air so that the wood have enough air to burn compleately.
When it burn it will increase in pressure just as in a engine before the piston start move down, but slower. Then I let the exhaus gas out to a turbine and it will run and the pressure will go down in the tank until the pressure in the tube is at atmospheric level.
You also can't just blow air into a vessel and have it spontaneously increase in pressure.
The system have all its solid fuel and compressed air it needs before it is ignited.
I do not plan to fill it with more air when it burn.
Something has to act on the air to move it (like the fan you are talking about). But if you use a fan to move the air, the fan is what is producing the energy (and also using the energy).
The fan I put in the tube can be running on electricity by wires through the tube wall but it need to run in a very high pressure and heat.
You really should look into how a steam engine works. What you are trying to do is similar, but missing some pieces.
I am not sure you understand what I am trying to explain here.
