15 Tons Gas-fired Steam Boiler for Dairy Industry

I. Project Background:

Yili Group, the largest dairy company in China, invested in a Green Production and Intelligent Manufacturing Demonstration and Application Project in Wuwei, Gansu Province. The total investment of the project is about 2.1 billion yuan (about 327 million dollars). Ten production lines have been built in the first phase. After completion, the production base will have a liquid milk production capacity of 603 tons/day (with an annual output of 180,900 tons), with an annual output value exceeding 1 billion yuan (156 million dollars). The steam boiler purchased in this project is mainly to meet the demand of production heat and heat supply in winter.

II. Solutions:

ZOZEN Boiler recommended to design 3 sets of 15 tons gas-fired steam boiler for the customer, 2 sets of boilers are in use and one for standby.

According to the project requirement, the boiler shall adopt natural gas as the fuel, therefore, ZOZEN Boiler recommended the WNS series. The WNS series gas-fired steam boiler has sufficient storage room and heating surface with large volume of furnace, the steam is with good quality and sufficient output with low water content. At the same time, the advanced low NOx burner is selected for the boiler to ensure the sufficient combustion of the natural gas, which effectively lower down the NOx emissions. In addition, this series of boiler applies advanced condensation technology to recycle the waste heat in the flue gas, to improve the inlet water temperature of and reduce the exhaust gas temperature, which increases the thermal efficiency up to more than 98%.
