Show 6. Conclusion 19 Safety of combustion systems is a matter of course but in addition the three factors of © energy saving, © low N O x emission, and (1) low cost are demanded. Their respective weight may change depending on the object, locality, and on the social situation. Under such circumstances, w e have developed and made practical, the combustion systems mentioned above as optimum combustion systems for forge furnaces in present day Japan. 1) The auxiliary-burner flame retaining two-stage combustion method which is a simple low NOx method was devised and using this method, a low N O x and low pressure drop twin regenerative burner, the PAX-R was developed. 2) Eccentric type are under development for further reduction of NOx, incorporating thick and thin fuel combustion in the PAX-R burner. 3) A compact self-regenerative burner, the PAX-SR which can conduct changeover combustion by one unit with the provision of a changeover valve was developed. 4) Forge furnace coping specifications for the rotary type regenerative burner, the RRX which contains a rotary duct and can conduct continuous combustion is under development. 5) Various developments have been made on parts other than on the regenerative burner system for forge furnace in working for improvement of the system. |
