basic information
■Heat Balance Analysis System and Clamp-On Ultrasonic Steam Flow Meter - The heat balance analysis system automatically calculates and quantifies the heat balance of steam-utilizing equipment. It continuously monitors the thermal efficiency of the equipment, and if the thermal efficiency deteriorates, it can narrow down the causes through analysis using AI technology. - The clamp-on ultrasonic flow meter for steam enables the "visualization" of steam flow in factories and equipment. It can be easily installed without the need for piping work, allowing for accurate measurements without the need to stop the operating equipment.
Applications/Examples of results
■Application Example: Heat Balance Analysis of Steam Used in Sterilization Equipment ・Applicable Products: Heat Balance Analysis System, Clamp-On Ultrasonic Flow Meter (for Steam and Liquid) Target Equipment: At a certain A factory, a heat balance analysis was conducted to improve the energy efficiency of steam used in sterilization equipment. This equipment uses steam to heat the hot water in the heat exchanger. System Configuration: For analysis, ultrasonic flow meters for steam, temperature sensors, and ultrasonic flow meters for liquids were installed, and the collected data was configured to be monitored remotely and in real-time on an internal evaluation server. Findings from the Steam and Heat Balance Analysis: Upon analyzing these causes, it was found that 1. the increase in product outlet temperature was due to a decrease in recovered heat caused by the aging of the heat exchanger, and 2. the occurrence of flash steam was due to the flow from high-pressure water to low-pressure piping. Additionally, it was determined that flash steam was generated by flowing from high-pressure water at 0.3 MPa(G) to piping at 0.0 MPa(G), and it could be separated and recovered for use in a flash tank, while waste hot water could be utilized for heat recovery with heat pumps and other systems.
