PT.Lontar Papyrus has built their pulp mill in Sumatra island since 1994.
During manufacture, the raw material needs to be cut, grinded and cooked, as per the capacity rising, the huge power and steam consumption makes the manufacturing cost higher and higher. For making their product more competitive, PT.Lontar Papyrus decided to build their own cogeneration energy plant, high-quality steam is used for making electricity and low-quality steam is used for process. Cogeneration boiler has high requirement for steam quality, pressure, and boiler smooth running. Because it needs to be installed on-site, it also requires the supplier to be profession for on-site installation. After many times visit and discuss, PT.Lontar Papyrus chose ZOZEN coal-fired steam boiler, by cooperating with local agent, ZOZEN full filled this big project successfully. The boiler has been running well and each target are reached too.
The rubber production of the outer layer of the wire and cable must undergo a vulcanization process, and the vulcanization process need the steam from boilers to heat and pressure the rubber. Anhui Cable is an enterprise specializing in the production of wire and cable. It mainly produces and operates 1E class K2, K3 and non-1E medium voltage power cables, various types of flame retardant and refractory special cables. In 2015, the principal of Anhui Cable purchased a 4-ton SZS Condensing Gas Fired Boiler in Zozen Boiler to provide steam for rubber vulcanization. The steam temperature was required to be between 140-180℃. After vulcanization, the natural cooling was performed, opened the valve, the steam condensate in the pipeline will go directly into the cooling pool. After steam cooling, fresh water can be added to the processed of drawing, annealing, ,water sealing, extruding, extruding rubber, mixed rubber, desulfurization and dust removal, which saves a lot of production water for
The processing and production of agricultural and sideline products, which involves dehydration, drying, refrigeration, freezing, salting and other technical processes, they all need a large amount of steam. Usually, such food companies purchase high-efficiency high-pressure steam boilers. As a long-established brand enterprise that pioneers the “new era of peanut leisure”, its main business is: sapid peanuts, sesame oil, chili power and snack food. After a period of investigation and comparison, the principal of the company chose to purchase two sets of horizontal gas-fired thermal oil heater(7 million kcal) at ZOZEN, which according to calculate the amount of steam used in production and processing of the products. The boiler of ZOZEN utilizes the high-temperature characteristics of the thermal oil heater to support low-pressure and high-temperature heat, can use a closed or opened circulate system according to the needs of users.
