4th coal fired hot water boiler for palm oil mill, ZOZEN SZS series boiler adopts the flue gas backflow technology

Under the background of economic globalization, more and more foreign exchanges seem to be an inevitable trend in all walks of life. For ZOZEN Boiler, the exchange with outsiders not only promotes the exchange of information, but also accelerates the pace towards internationalization.

In the process of smelting molten steel, pouring steel ingots, and producing finished castings, a large amount of steam is consumed. The superheated steam generated by the boiler provides the required thermal energy for its process. Through open bidding, ZOZEN stood out among many boiler manufacturing enterprises with its own technical advantages and quality assurance, and provided China Second Heavy Machinery Group Corporation with a large superheated steam boiler, 4th coal fired hot water boiler for palm oil mill.

ZOZEN thermal oil heaters have significant advantages in precise temperature control and safety performance. The intelligent control system is designed to adjust the temperature with one button. After the specified temperature is set, the heat medium oil will maintain the state to provide the stable heat source. At the same time, ZOZEN thermal oil heaters are equipped with automatic alarm, automatic locking and other safety and explosion-proof devices, which adds an extra guarantee to the safety of users.

The grate bracket adopts double brackets, the lower channel steel, the upper light rail, the upper heat, the lower force, which has changed the structure of the traditional grate bracket angle steel plus friction bar, the grate bracket is not deformed. The active stoker is operated on the light rail and it is tested in the cold state for 48 hours before leaving the factory. Never run sideways, stuck, which ensure the smooth operation of the stoker.

In terms of welding technology, ZOZEN longitudinal and circumferential seam welding adopts advanced automatic submerged arc welding technology, and 100% X-ray detection is carried out on the welding seam to ensure the welding quality. The welding of the smoke tube and tube sheet adopts pre-expansion first to eliminate the gap between the tube and tube sheet, and then adopts the automatic argon arc welding technology, which can effectively eliminate the stress and extend the service life of the boiler.

In the rubber industry, steam boilers are widely used in the processes of rubber calendering, vulcanizing and drying. PT.Industri Karet Deli is a large rubber enterprise in Indonesia, it planned to upgrade production equipment to improve their core competence. The company contacted ZOZEN and signed the purchase contract of SZL 20 tph SZL series coal-fired boiler. This series of water tube boilers adopts unique grate bars and appropriate air registers to ensure the stable running of boilers and improve the thermal efficiency.

This quality mobilization meeting marked the start of ZOZEN’s quality improvement work. Quality is the life of an enterprise. For survival and development, every enterprise has to improve the product quality and keep innovation for higher goals. Next, ZOZEN Boiler will unremittingly pursue high quality for perfection with practical actions, so as to rank the top in the industrial boiler industry and write a new chapter for the quality of ZOZEN Boiler, 4th coal fired hot water boiler for palm oil mill.
