what is a coul fueled boiler, ZOZEN gas-fired boiler greatly improves energy utilization


The former part of ZOZEN SZL coal fired boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace there are dense convection tube bundles between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.
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.
what is a coul fueled boiler, The furnace of ZOZEN SZL series coal fired boilers adopts a close-packed a close-packed arrangement of water wall tubes. The application of close-packed water wall in furnace design changes the traditional structural form of the original industrial boiler furnace water-wall, effectively preventing high-temperature flue gas from scouring and radiating the furnace. Furnace radiation area is large, maintenance workload is small, overall weight is light.
ZOZEN is the first in China to adopt arched tube sheet and threaded smoke tube structure. Threaded smoke pipe is a high-efficiency heat transfer element researched by ZOZEN for many years. After continuous optimization, its heat transfer coefficient is 1.8 times higher than that of ordinary smoke pipe, which increases heat conduction.
what is a coul fueled boiler, ZOZEN will always adhere to technology research and development, and continue to provide efficient and energy-saving boiler systems for enterprises, further contributing to the high-quality development of the domestic fine chemical industry.
