Title: Innovations of Stanislaw Michalak in Combustion Gas Treatment
Introduction
Stanislaw Michalak is a notable inventor based in Reichshof, Germany, recognized for his significant contributions to the field of combustion gas treatment. With a total of 12 patents to his name, Michalak has developed innovative processes aimed at reducing harmful emissions from large boilers.
Latest Patents
Among his latest patents, Michalak has introduced a simplified and efficient process for reducing nitrogen oxides (NO.sub.x) and sulfur oxides (SO.sub.x). This process enhances the removal of SO.sub.x and particulates from combustion gases. In a primary treatment zone, a slurry containing an alkaline SO.sub.x-reducing composition and a nitrogen-containing composition is introduced into combustion gases at temperatures ranging from about 900°C to about 1300°C. The gases are initially cooled by contact with steam-generating means and subsequently by a gas-to-gas heat exchanger. Following this, the gases undergo secondary treatment, where they are humidified and cooled further by a water spray or aerosol, reducing the temperature to 100°C or below. The contact between the SO.sub.x-reducing composition and the humidified gases is maintained for a reaction period of at least 2 seconds, allowing for the effective separation of particulate solids using a fabric filter. This innovative approach achieves reductions of SO.sub.x greater than 80%, with a preference for reductions between 90% to 95%.
Another significant patent involves an apparatus for preheating combustion air. This air preheater utilizes hot, NO.sub.x-containing flue gases from the same or an independent combustion process to preheat the air for combustion. The apparatus not only preheats the air but also reduces the NO.sub.x contained in the flue gases. A regenerative or recuperative type air preheater is employed, with heat exchange elements coated with a catalyst for NO.sub.x reduction. The coatings are strategically placed to optimize the reaction conditions based on the flue gas temperature.
Career Highlights
