Good day and night, gentlemen! Hello from Yakutia, USSR. The problem is this: the wood and the coal in the boiler furnace is not moving, solid body. They do not replace burned-out and remain in place always. No gravity in the furnace. I need gravity for wood and coal. Is it real or not? A gas generator is necessary to simulate from A to I (Z).

Thank you! I'm all powders are poured, but they do not burn as it should. It is necessary that the fire was near the grate, but not to move to the pump. Wood and coal must move down into the combustion zone. Does not work for two reasons: 1 - there is no gravity solids. 2 - no the porosity of coal, wood, coal dust. There should be a gap so the air is passed, and maintained fire not far from the lattice. The flame height shall be vested in the level of oxygen O2 - fan speed. It's probably not a program can do. A lot is not completed yet in physics. Yes, you are right, there is no Soviet Union to evil, to hatred, to win, but he is always there where it is necessary to stop it. Thank you very much for Your attention and loss of time.

Where is the porosity, where the ratio of fill volume? All nonsense and not actually working. The aerodynamics programme is shit.

Nonsense. The aircraft falling into a spin:

 f You are to raise their children according to Your unrealistic games, then You'll never catch our planes and will never fly above them. Good luck, the European Union and more truth in the "Game". Farewell to Europe and Your game.
