Dedicated to the research and engineering demonstration of waste heat utilization technology in thermal power plants, the company has actively conducted research on the replacement of traditional heat exchangers with vacuum heat pipe phase change heat exchangers. Vacuum phase change heat pipe technology completely isolates the heat exchange on the flue gas side and the water side, avoiding cooling water leakage into the flue, which could affect the safe and stable operation of dust collectors and ash conveying equipment. Vacuum phase change heat pipe heat exchangers are characterized by being safer, more reliable, and capable of long-term continuous operation.
