Latest Patents

One of Koda's latest patents is a low-NOx boiler. This innovative boiler design includes a burner for burning gaseous fuel and heat transfer pipes that heat water using the combustion heat from the burner to generate steam. The system features a steam drum that communicates with the heat transfer pipe, accumulating steam, and an exhaust gas duct that expels combustion gases outside the boiler. A unique aspect of this design is the inclusion of an unburnt gas burner in the exhaust gas duct, which burns unburnt content in the combustion gas. This burner utilizes a nozzle for injecting a premixture of fuel and combustion air, along with a flame holding plate that helps to shorten the flame length and reduce NOx emissions. The innovative design significantly lowers the concentration of NOx discharged from the system.
