Patent number: 11740022Abstract: A control scheme for a furnace can use real-time and historical data to model performance and determine relationships between different data and performance parameters for use in correcting suboptimal performance of the furnace in real-time. Operational parameters can be logged throughout the cycle for all cycles for a period of time in order to establish a baseline. This data can then be used to calculate the performance of the process. A regression analysis can be carried out in order to determine which parameters affect different aspects of performance. These relationships can then be used to predict performance during a single cycle in real-time and provide closed or open loop feedback to control furnace operation to result in enhanced performance.Type: GrantFiled: July 22, 2020Date of Patent: August 29, 2023Assignee: AIR PRODUCTS AND CHEMICALS, INC.Inventors: Martin Lawrence, Avishek Guha, Reed Jacob Hendershot

Patent number: 11680704Abstract: A novel two-chamber design for thermal boilers is presented in this document. The boiler uses spiral-shaped tubes with conical and flat portions which form a combustion chamber. The use of a direct flame burner causes exhaust gas turbulence and increases the gas pressure in the main chamber. The high-pressure gases, which have lost their kinetic energy due to collision with spirals, leave the main chamber and enter into the secondary chamber, where their energy is used to preheat inlet water.Type: GrantFiled: April 29, 2021Date of Patent: June 20, 2023Inventor: Hossein Rayramesh
