Shaoxing, Zhejiang: Coal and gas pollution from printing and dyeing companies

Recently, the printing and dyeing enterprises in Shaoxing County, Zhejiang Province have realized the conversion of coal to gas, which not only solves the problem of oxidation* emissions in the production process, but also ensures the stability of the fabrics to the utmost.

Jiang Xuye, deputy general manager of Zhejiang Honglanlan Textile Printing and Dyeing Co., Ltd., said: “If coal is burned, the general thermal efficiency is only about 80%. Now when burning natural gas, the thermal efficiency reaches over 98%. You look at the cloth speed that we were so thick before (only Can) open to 42 yards, can now open to 50 yards. SO2 emissions are almost zero, from the environmental aspects of the overall development of our business is still useful."

"Coal to gas" is the use of direct combustion of natural gas to replace heat-conducting oil boilers. For this purpose, companies invest more than two million yuan to import this set of natural gas stereotyped machine imported equipment. It uses computer numerical control constant temperature, high heat utilization rate, greatly improved Production efficiency. In addition, the most irritating CO2 emissions from printing and dyeing companies have been reduced to almost zero.
