This series of boiler has many advantages such as compact structure, high thermal efficiency, low energy consumption, and good quality, so it has strong market competitiveness.

ZOZEN Boiler has invested a lot of technical force in improving boiler’s energy-saving performance. The structure and operating principle of organic heat carrier boiler cause that the exhaust gas temperature at its end is around 300°C and result in a huge waste of heat energy. In order to reduce heat loss, ZOZEN technicians add a variety of energy-saving devices at the end of boiler’s flue gas duct to improve the overall thermal efficiency of organic heat carrier boiler through the recovery and utilization of high-temperature flue gas, which helps many companies to achieve the goal of energy saving and consumption reduction.

The header is not an independent component, but a component consisting of water-cooled walls, economizer, superheater and other components. Therefore, there are water-cooled wall header, economizer header, superheater header and so on. The function of header is to collect or distribute the steam and water working medium, reduce the transmission and connection pipes of working medium, reduce the number of drum holes, so as to improve the safety performance of drum.
