disadvantages of chain grate boilers, ZOZEN gas-fired energy-saving boilers get the favor of the chemical industry

In recent years, with the deepening cooperation between China and Africa, ZOZEN and KPC have built a friendly cooperation relationship with the oil-fired steam boiler project. In the petroleum processing industry, steam is the main factor affecting the energy consumption of enterprises. The safe, efficient and energy-saving boiler system directly determines the quality of oil products and the economic benefits of enterprises.

Recently, ZOZEN successfully entered the Jordan market again. Established in 2003, Classic Fashion Apparel Industry is a Jordanian company that mainly produces high-quality garments with fine craftsmanship. The company decided to import multiple sets of hot water boilers from China under the "Belt and Road" policy. Relying on excellent product quality and good market reputation, ZOZEN successfully seized this opportunity and reached a cooperation agreement with the company.

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.

ZOZEN’s YLW series thermal oil heater is developed based on chain grate. It can provide high-temperature heat source at various temperatures below 350℃, suitable for various production processes such as dyeing, drying, slashing and printing which require high-temperature and low-pressure heating supply. The YLW series boiler also can realize the precise temperature control via advanced oil temperature and pressure control system to greatly improve the heat energy utilization rate. Recently, Kay & Emms has decided to upgrade the production equipment and signed a cooperative agreement with ZOZEN on the YLW series coal-fired thermal oil heater project, disadvantages of chain grate boilers.

disadvantages of chain grate boilers, ZOZEN boilers adopt the ultra-low nitrogen burner with flue gas recirculation method to realize low NOx emission. Adding flue gas to the combustion air to reduce the oxygen content in the combustion air and lower the flame temperature at the combustion center, so as to greatly reduce the generation of NOx. At the same time, superimposed use of world advanced technologies such as staged combustion of ultra-low nitrogen burner and internal flue gas circulation realizes the stable and low emission of NOx.

ZOZEN has set up a total of seven process stopping points throughout the production process, which are strictly controlled by different engineers, independent of each other and supervised each other, so that problems can be found and solved in time. If any workpiece is unqualified, it cannot enter the next process, which is the quality control of the entire production process of ZOZEN.

All boilers are subject to damage if proper water treatment procedures are not followed. This is an important consideration both during operation and when the boiler is idle. To avoid damage and costly repairs, monitor water chemistry routinely and ensure that you are supplying your boiler with soft water at all times.
