  • Patent number: 5954498
    Abstract: Burner firing method and device are presented where an oxidizing oxygen-fuel burner is fired at an angle to the reducing air-fuel burner flame to reduce overall NOx emissions from high temperature furnaces. The oxidizing oxy-fuel burner stoichiometric equivalence ratio (oxygen/fuel) is maintained in the range of about 1.5 to about 12.5. The reducing air-fuel burner is fired at an equivalence ratio of 0.6 to 1.00 to reduce the availability of oxygen in the flame and reducing NOx emissions. The oxidizing flame from the oxy-fuel burner is oriented such that the oxidizing flame gas stream intersects the reducing air-fuel flame gas stream at or near the tail section of the air-fuel flame. The inventive methods improve furnace temperature control and thermal efficiency by eliminating some nitrogen and provide an effective burnout of CO and other hydrocarbons using the higher mixing ability of the oxidizing flame combustion products.

  • Patent number: 5888063
    Abstract: A method of quick purging beds of a regenerative fume incinerator which is practically applicable for use in 2, 3 and 4 bed incinerators. For a very short purge period near the end of an operating time cycle, the bed being switched from receiving impure gases to discharge of clean gas is purged of impure gases by being supplied with clean gas discharged by the incinerator. The quick purging takes less than 4% of the cycle time and thus inflow of impure gases is stopped for a very brief period when this quick purge method is used in a 2 bed incinerator. When using this quick purge method in a three or four bed regenerative fume incinerator there is always at least one bed receiving impure gases. This quick purge method improves the quality of the discharged clean gas without significant loss of thermal efficiency and without significant reduction in operating capacity.

  • Patent number: 5007824
    Abstract: The invention is directed to an arrangement of high thrust burners with control systems for a heating furnace which heat metal or similar product, in order to erase developing cold skid marks. The location of these burners is specified, transversely and longitudinally as well as their position with the product face. This invention considers the flow of gases inside of the furnace and the necessary burner characteristic required for the application of these burners to the developing skid marks and the reasons for the specifications. The burners are required to be such that the maximum available heat in the flame is applied at the spot required in order to heat those spots at a faster rate than the cooling effect of the water cooled parts, which are the initial causes of the cold spots. Moreover, it is specified as to the control systems and to the part in which they play in the operation of the skid mark erasure burners.
