Ice extraction from wind turbine using flow of hot air through blade

Abstract: In this paper high the ice accumulated on the wind turbine blade is removed by passing hot air through the blade. The hollow tubes are embedded in the wind turbine blades. The hollow tubes may be circular on cross section or of any suitable shape. The air is heated by an electrical heating or by gas geyser. First the air is compressed with help of a compressor. Then that air is passed through the electric heater or gas heater. The hot air is then passed through the wind turbine blade. When the hot air is passed through the wind turbine blade, the ice melts and falls down. Hot air is passed through the wind turbine blade after frequent intervals of time when the environmental conditions are favorable for icing. The process of deicing is fast.

Drying of coating film

Abstract: PROBLEM TO BE SOLVED: To hardly cause a blister and a pinhole to a coating film and to reduce an energy cost at the time of drying a coating film formed on the surface of a matter to be coated. SOLUTION: The coating film is heated from the interior side by irradiating the coating film formed on the surface of the matter 1 to be coated with mid infrared rays using a mid infrared electric heater 2 at a mid infrared zone A. The solvent and the moisture incorporated in the coating film is evaporated by this heating to release gas to the atmosphere and also the coating film is cured. When the coating film from which the gas is released is heated, since the character of the infrared rays is not restricted, far infrared rays by a combustion gas heater 3 is used. In this way, an energy cost is reduced.

Method for heating fuel cell

Abstract: PURPOSE:To miniaturize a gas heater to reduce the cost of equipment by heating the cathode gas of individual fuel cells one by one at the cold start of the fuel cells together with blowers in a circulation line. CONSTITUTION:A blower 26 and a cathode gas heater 27 are driven with stop valves 34, 36 open and all the other valves closed, to heat the cathode gas of a first molten carbonate fuel cell 11. When heating of the cell 11 is finished, a second molten carbonate fuel cell 12 is heated with stop valves 38, 40 open and all the other valves closed. When heating of the cell 12 is finished, the next fuel cell is heated and then other fuel cells are heated similarly, and finally the anode gas of an (n) molten carbonate fuel cell 1n is heated with stop valves 42, 44 open and all the other valves closed. Since the individual cells 11, 12...1n have their cathode gas heated one by one, a capacity for one cell is sufficient for the capacity of the cathode gas heater 27. The expensive heater 27 can then be miniaturized and equipment cost can be reduced.

Heat transfer characteristics in the channel of a segmented electric-arc gas heater

Abstract: An experimental investigation has been made of heat transfer in a segmented gas-stabilized electric-arc heater. It has been found that in the pressure range 4·103−200·103 N/m2, the heat transfer in the heater channel may be expressed in terms of the Knudsen number, and it is shown that the heat transfer decreases with increased expansion in the channel.
