1. Working Principle: During the production process of industrial kilns, the flue gas emitted from the kiln is generally above 200°C. We can utilize this flue gas to generate steam through a superconducting waste heat boiler. The steam can be used for heating fuel, pipeline insulation, heating, and other purposes, as well as for preheating combustion air. Industrial kiln flue gas typically has characteristics such as high dust content and strong acidity. Our company's superconducting heat exchanger, used for steam generation, has proven through long-term practical application that the system equipment is energy-efficient and reliable.

2. System Advantages:
     1) The pressure drop on the flue gas side is small, meeting the requirements for negative pressure inside industrial furnaces.
     2) Resistant to ash accumulation; the equipment is equipped with cleaning ports for online cleaning.
     3) The tube wall temperature is controlled above the acid dew point to avoid low-temperature corrosion.
     4) Service life can exceed 10 years.
     5) The system payback period is short, generally recovering the investment cost within about one year.
