  • Patent number: 12693009
    Abstract: There is provided an AI-based air damper control system and method for industrial boilers. An AI-based optimal air damper control method according to an embodiment calculates energy efficiency under a given control condition and an environment by extracting energy efficiency-related data from industrial boiler operational data and analyzing a correlation between corresponding data, trains an AI-based optimal air volume-for-load prediction model by using the extracted data and the calculated energy efficiency as training data, and derives an air volume condition that results in peak energy efficiency under a given load, based on the trained optimal air volume-for-load prediction model, and automatically controls the air damper according to the corresponding air volume condition.

  • Patent number: 10488042
    Abstract: The present invention relates to a method for detecting a blockage in an exhaust flue of a gas boiler, comprising: (A) a step for conducting an ignition process according to a user set temperature requested from the outside and performing temperature control to reach the user set temperature; (B) a step for determining whether the current fan RPM of a driven blower exceeds a reference fan RPM; (C) a step for calculating a difference between temperature values of supplied heating water and collected heating water that are detected by temperature sensors when heating water is supplied and determining whether the calculated value is less than a preset reference temperature value when it is determined that the current fan RPM exceeds the reference fan RPM; (D) a step for determining whether the elapsed time elapses a preset setting time based on the determination time point of the step (C) when it is determined that the calculated value is less than the reference temperature value; and (E) a step for displaying,

  • Patent number: 9917317
    Abstract: The present invention relates to a combined fuel cell and boiler system, and comprising: a fuel cell portion for receiving supplied outside air and raw material gas and generating electricity through a catalyst reaction; and a boiler portion comprising a latent heat exchanger, which is connected to an exhaust gas pipe of the fuel cell portion, for collecting the latent heat of self-generated exhaust gas with the latent heat of exhaust gas from the fuel cell portion. The present invention can effectively increase the efficiency of a boiler by supplying the exhaust gas from the fuel cell to the latent heat exchanger in the boiler, so as to be heat-exchanged in the latent heat exchanger with the exhaust gas from the boiler and then discharged, and can simplify the composition by unifying exhaust gas pipes.

  • Publication number: 20100000948
    Abstract: Disclosed therein is a water treatment equipment using pulsed ultraviolet lamp, which emits pulsed ultraviolet rays of high power and high transmission. The water treatment system can be usefully used in a purification plant or in a waste water treatment plant of high turbidity since the UV lamp adapted for emitting the pulsed UV rays is higher in power and longer in a transmission length than the conventional continuous UV lamp.
