The decline in the consumption of thermal oil boilers can be attributed to several factors: - Combustion Technology: Modern thermal oil boilers employ advanced combustion technologies such as premixed combustion and afterburning, which ensure complete fuel combustion, enhance thermal energy utilization, and thereby reduce energy consumption. - Heat Recovery: Thermal oil boilers typically generate a significant amount of excess heat during flue gas emissions. By utilizing heat recovery systems like flue gas heat recovery boilers or flue gas heat exchangers, the excess heat in flue gases can be recovered and reused, improving energy efficiency and reducing consumption. - Intelligent Control Systems: Contemporary thermal oil boilers are equipped with intelligent control systems capable of real-time monitoring and adjustment of operating parameters such as temperature, pressure, and flow rate. This control and adjustment ensure optimal boiler operation, avoiding unnecessary energy waste and loss. - Energy-saving Retrofitting and Optimization: For older thermal oil boilers, energy-saving retrofitting and optimization can be performed. This includes installing energy-saving equipment like variable frequency drives and modified burners to enhance energy efficiency. Additionally, optimizing the boiler system, such as improving pipe insulation and reducing leaks, can further reduce energy loss. - Energy Management and Maintenance: Effective energy management and regular equipment maintenance are crucial factors in reducing energy consumption. Implementing energy management measures such as energy monitoring, metering, and fostering energy-saving awareness can identify and resolve energy waste issues. Regular equipment maintenance and upkeep ensure the smooth operation of the equipment, preventing unnecessary energy loss. In summary, the decline in energy consumption of thermal oil boilers can be achieved through combustion technology, heat recovery, intelligent control, energy-saving retrofitting, and effective energy management.
