improvement in efficiency of water tube boiler, ZOZEN effectively controls steam boiler prices

ZOZEN Boiler (Wuxi) is a designated manufacturer of boilers and pressure vessels approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China. ZOZEN holds the A-grade boiler and BRⅡ-grade pressure vessel manufacture licenses, ASME “S” and “U” certificates with steel seals and fully passes the ISO9001:2000 international quality system certification.

Facing the challenges of 2020, Wuxi Zozen Boilers Co., Ltd. has made great progress. In July, ZOZEN's Wuwei Yili project team, with wonderful performance on project construction and management in the second quarter, was awarded "Excellent Project Team". ZOZEN will continue to provide high-quality heat supply equipment for Yili Group's demonstrative project of green production and intelligent manufacturing.

The SZL series biomass-fired chain grate boiler is safe and efficient with a capacity of 4-35 tph (hot water boiler: 2.8-29MW) and a thermal efficiency of over 88%. By extending the furnace arch, increasing the furnace height and adjusting the width and length of grate, ZOZEN takes the lead in solving the problems that easily occur in biomass-fired boilers such as furnace arch collapse, furnace door burnout, hopper tempering and tube wall coking. It has the characteristics of wide fuel adaptability, small covering area, convenient installation and high thermal efficiency.

ZOZEN SZS series boiler body is designed with D-type chamber combustion structure. The furnace is on right side and the convection heating surface is on left side. The membrane type structure is adopted for the circumference of the furnace body, the wall between the furnace and the convection zone, the front and rear walls of boilers body. The furnace pressure is designed to be greater than 6000Pa, improvement in efficiency of water tube boiler.

improvement in efficiency of water tube boiler, ZOZEN is the first in China to adopt arched tube sheet and threaded smoke tube structure. Threaded smoke pipe is a high-efficiency heat transfer element researched by ZOZEN for many years. After continuous optimization, its heat transfer coefficient is 1.8 times higher than that of ordinary smoke pipe, which increases heat conduction.

During the “Thirteenth Five-Year Plan” period, China’s oil refining industry will focus on transformation and upgrading by vigorously eliminating the outdated production capacity to improve the equipment scale and technology level. The boiler, as an important energy equipment, is essential in the petroleum refining process. Relying on technical advantages and rich project experience, ZOZEN Boiler has reached the friendly cooperation with enterprises such as PetroChina Jinxi Petrochemical Bihai Company, Sinopec Hubei Petroleum Branch, Dongfang Hualong, Rizhao Binhai Petrochemical, Honghai Chemical and so on.

This project is of great significance to ZOZEN, promoting ZOZEN’s development in Central Asia and building a strong foundation in future international development.
