metallurgy of fire tubes boiler, ZOZEN gas-fired oil-fired dual-fuel boiler gets the approval of the industry

Due to continued success and growth, ZOZEN Boilers introduces a new team to support its strategic vision to deliver more efficient, innovative and sustainable products and services, metallurgy of fire tubes boiler.

As a well-known industrial boiler brand at home and abroad, ZOZEN SZS series gas-fired boiler has become an important heat source equipment for the grain and oil production lines of Yihai Jiali Group with the outstanding performance advantages.

The DZL series biomass-fired horizontal three-pass water-fire tube chain grate boiler is pre-assembled boiler with a capacity of 2-20 tph (hot water boiler: 1.4-14MW) 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, metallurgy of fire tubes boiler.

metallurgy of fire tubes boiler, 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.

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.

metallurgy of fire tubes boiler, With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers feature high efficiency and low emissions. They adopt single-drum structure and a chain grate. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In order to expand the capacity, PT. New Hope Indonesia introduced ZOZEN DZL series coal-fired steam boiler to provide efficient and reliable heat source guarantee for feed production. 

Based on low-nitrogen and energy-saving technology, ZOZEN is committed to developing widely used and advanced technology, products and services. In this way, ZOZEN provides heat source support for various industries around the world to promote future cutting-edge business and realize the application dreams of users in various fields. The low-nitrogen boilers designed by ZOZEN can control the emission of NOx to lower than 30mg, which are widely used in various industries and are attractive for the national and international market.
