<p>PURPOSE: To efficiently crack toxic gases by irradiation with a laser beam of an optimum wavelength. CONSTITUTION: This apparatus is constituted by providing a cracking furnace 1 for cracking the toxic gases by the laser beam A cast from a laser oscillator 7 with a diaphragm mechanism 2 for changing the velocity of flow of the toxic gases, providing this diaphragm mechanism 2 with a gas current speed meter 8 and providing this current speed meter 8 with a controller 14 for controlling the diaphragm mechanism 2 according to the gas flow velocity detected by the current speed meter 8. Then, the flow velocity in the optical path of the laser beam A of the cracking furnace 1 is controlled to the prescribed flow velocity at which the optimum wavelength (the wavelength at which the toxic gases are liable to be cracked) is attained by the diaphragm mechanism 2 even if the flow velocity of the toxic gases introduced into the cracking furnace 1 from the toxic gas inflow port 5 is unstable, by which the toxic gases are always efficiently cracked and the specified cracking performance is maintained at all times.</p> |
