7th biomass fired thermal oil boiler in pakistan, ZOZEN Boiler has a comprehensive quality control system

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.

7th biomass fired thermal oil boiler in pakistan, Samsung Electronics is the largest electronics company in Korea. As early as 2012, Samsung Electronics has invested 7 billion US dollars to build a semiconductor production base in Xi'an. Boiler is an important piece of equipment to ensure the constant temperature, constant humidity and ultra-clean environment of the semiconductor production workshop.ZOZEN finally won the trust of each other with excellent comprehensive strength, and started the first cooperation between the two parties since then.

The SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation.

Nantong Kedi Medical Material Technology Co., Ltd. is engaged in the research, development and production of products such as medical non-woven fabrics, dressings, wound care materials, surgical sanitary products, etc. The products are very popular in the market. In July 2019, Kedi Medical Material decided to expand the production project of processing 8,000 tons of medical non-woven fabrics. As an important piece of equipment of the hot-rolled non-woven fabric production line, the performance of energy saving and high efficiency of gas-fired thermal oil heaters will directly affect the product quality and production efficiency of Kedi Medical Material. With advanced production technologies, scientific testing methods and considerate after-sale service, ZOZEN provided Kedi Medical Material with the YQW series horizontal thermal oil heaters.

The grate bracket of ZOZEN’s chain grate boilers adopts double-layer structure. The lower layer uses channel steel and the upper layer uses light rail. The upper layer is heated and the lower layer is stressed. It changes the traditional grate bracket using angle steel and friction strips without  deformation. The active grate runs on the light rail with a 72-hour cold test run carried out before leaving the factory to ensure the smooth operation of grate without deviation or jamming.

The key processing technologies of the steel plate of ZOZEN gas fired boiler, such as the slanting of the steel plate, the circle, and the drilling of the drum, all adopt advanced CNC processing technology to reduce assembly stress and extend the service life of the boiler. Process to ensure welding quality, all longitudinal and circumferential welds are 100% radiographically inspected, 7th biomass fired thermal oil boiler in pakistan.

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