ZOZEN is an industrial boiler manufacturing enterprise with strong comprehensive strength, has obtained a variety of international certifications including ASME; what’s more, ZOZEN has achieved fruitful results in the international market. ZOZEN won the trust of PT.Industri Karet Deli with rich experience in the rubber industry. Considering that PT.Industri Karet Deli uses bituminous coal as boiler fuel, the sales manager of ZOZEN recommended SZL series coal-fired water tube boiler after a field survey. This series of water tube boilers adopts closely-aligned membrane water wall structure, changes the traditional furnace water wall structure of original industrial boilers, which effectively prevented the abrasion and radiation of high temperature flue gas to the furnace; this series of boilers uses unique grate bars and appropriate air registers to ensure the stable running of boilers and improve the thermal efficiency.
