Chemical Industry 4-ton Natural Gas Fired Steam Boiler Project
Case introduction

Yunnan Phosphate Group Co., Ltd. is a wholly-owned subsidiary of Yunnan Yuntianhua Co., Ltd., and its main business scope is geological exploration, phosphate mining and phosphating. In order to cope with the increasingly fierce market competition, Yuntianhua Group, the headquarters, carried out a pilot-scale technology development project with an annual output of 1,500 tons of 2,4- difluorobenzene and p-fluoronitrobenzene in Jinning Industrial Park, Kunming City, Yunnan Province.

 

I. Customer Demand:

In the process of producing various fluorine-containing nitrobenzene products, high-temperature steam is relied on to provide continuous heat energy for key processes such as fluorination and rectification. At the same time, adhering to the company's philosophy of circular economy and resource reuse, Yunnan Phosphate Group highlighted the high degree of automation, energy saving and emission reduction performance of boilers when selecting heating boilers for the project, and the emission needs to meet local environmental protection requirements.

 

II. Solutions:

1. Considering the high-altitude of the project location Yunnan, ZOZEN Boiler recommended the WNS series gas-fired steam boiler with large volume of combustion room, coping with the low-NOx burner to ensure the sufficient combustion of the natural gas, which effectively overcomes the problem of insufficient output caused by high elevation. At the same time, the low nitrogen combustion technology adopted by the boiler can effectively reduce NOx emission and help Yunnan Phosphate Group easily meet the local environmental protection emission standards.

 

2. The economizer and condenser can be added to the end of the smoke tube, which use the waste heat in the flue gas to raise the inlet water temperature and lower the exhausted gas temperature, thus improves the thermal efficiency up to 98%.

 

3. ZOZEN WNS series steam boiler has a high degree of automation in operation, it can adjust the combustion, water level, temperature and steam pressure automatically, which helps to avoid the operational errors caused by human factors and meeting the requirements and company philosophy of Yunnan Phosphate Group.

Customer feedback—— Yunnan Phosphate Group Co., LTD.

The boiler manufactured by ZOZEN Boiler adopted advanced technology and automatic operation process, with good-quality and sufficient steam output, which provided a stable heat source for our production line. Furthermore, the energy conservation of the boiler was outstanding, the technician of ZOZEN Boiler set up the condensing water recovery system to recycle the steam condensate.
