automobile condensing oil steam boilers, scientific research design never stops-the soul of ZOZEN boiler design office
As we all know, quality is the foundation of enterprise development and the key to establishing a brand image. Since the establishment of ZOZEN Boiler in 1988, high product quality has become the fundamental guarantee for ZOZEN’s continuous development in the fierce market competition.


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, automobile condensing oil steam boilers.
In the field of industrial boiler manufacturing, ZOZEN natural gas fired boiler, with years of technological accumulation, advanced manufacturing technology and outstanding performance advantages, is outstanding among similar products and has become the common choice of all walks of life. This time, ZOZEN Boiler and Dalishen Technology Group reached the cooperation to seek the common development.
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.
The longitudinal and circumferential seam welding of ZOZEN adopts advanced submerged arc automatic welding technology to ensure the welding quality. All longitudinal and circumferential seams are subjected to 100% radiographic inspection, automobile condensing oil steam boilers.
ZOZEN has proved its competitive advantage with its high product quality. In the future, ZOZEN will spend more time and energy on the innovation of gas-fired boilers, and capture more market share.
