By Nick Syred, Artem Khalatov

The NATO ARW complicated Combustion and Aerothermal applied sciences: Environmental safety and toxins savings, used to be held in Kiev, may possibly 2006. The workshop used to be Co-Directed via Profs. N. Syred and A.Khalatov, winners of the NATO clinical Prize 2002, and used to be geared up via the Institute of Thermophysics (Ukraine) and Cardiff collage, united kingdom. the first Workshop ambitions have been to evaluate the present wisdom on complex combustion and aerothermal applied sciences offering decreased environmental effect, to spot instructions for destiny study within the box, and to advertise the shut relationships and company contacts among scientists from NATO and associate nations.

An additional energy resource is petrocoke, derivable as a result of hydrocarbon production by the thermal processing of oil sands; for instance in Canada there are mountains of petrocoke. Petrocoke is a solid fuel consisting of fixed carbon, tar and ash. Direct utilization of petrocoke is difficult because of its hardness and high tar content. In connection with this, the development of solid fuels technologies which would be environment friendly and efficient is of a primary importance.

The principal components are: a plasma generator-reactor, 1; slag trap, 2; syngas and slag separator chamber, 3; syngas cooling chambers, 4, 5, 6; pulverized fuel feeding system, 8; and a steam feeding system, 9. The zones of heat release due to the arc plasma, and of heat absorption by the solid fuel and gas streams, are combined in the same plasma generator-reactor chamber, 1. 04 m, and the inlet pipes for pulverized solid fuel (pf) and plasma-forming gas. 02 m, and bounded at its bottom side by a graphite orifice.

MESSERLE AND A. B. USTIMENKO The heat loss with the effluent gases is determined from the effluent gas temperature (Tg), flow rate (G1), and composition obtained through the gas analysis. The measured temperature, pressure, and composition of gases are fed into the TERRA code4, and the specific enthalpy of the effluent gases is computed for the specified values of the parameters mentioned above. The gas mixture heat output is calculated as follows: W6=H6G1, kW, where T g H = ∫ C ⋅ dT 6 p 300 is the specific enthalpy of the gas mixture.
