ZOZEN Boiler Condensing Gas-Fired Boiler Realizes Energy Conservation and Consumption Reduction in Enterprise

Boiler condensed water recovery technology refers to the condensed water released from steam using equipment is recovered by a recovery device and sent to the boiler or other places where heat is used for secondary use. The condensed water recovery technology has good energy-saving and water-saving effects. After in-depth research and test on this technology, ZOZEN Boiler successfully obtained the patent of steam boiler condensed water recycling device (patent No. ZL20172001307.4), which was successfully applied in many projects.

ZOZEN Boiler uses the condensed water recovery technology well

In one of the customer's projects, ZOZEN Boiler provides a set of gas-fired steam boiler solution by combining condensed water recovery technology.

The exothermic low-temperature steam flows back to the steam condenser, and after condensation, it returns to the gas-fired steam boiler for reheating into steam. In this way, the steam loss in the project is only about 3%. Condensed water is used as boiler make-up water, which also increases the temperature of boiler feed water and reduces the fuel consumption. Generally, the average temperature of boiler make-up water is 20℃, and the temperature of steam condensate recovery is about 70℃. Under the same condition, when water with high temperature is heated into steam, it absorbs less heat energy.

ZOZEN gas-fired boiler is reliable in quality and stable in performance

ZOZEN Boiler recommends the SZS series gas-fired steam boiler for the project. The series of boiler has the advantages of high thermal efficiency, low emission and automatic operation. The boiler combustion chamber adopts membrane wall with narrow spacing, which has good air tightness and small heat loss. At the same time, the front and rear walls of the boiler body adopt membrane structure, which greatly improves the service life more than 20 years.

The project site view of ZOZEN gas-fired steam boiler

The boiler system is equipped with low-NOx burner and the technology of flue gas external circulation to effectively control the generation of nitrogen oxides. It is tested that the actual NOx emission concentration of ZOZEN gas-fired boiler is lower than 30mg/Nm³.
