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.
With the rapid development of animal husbandry, aquatic products and other aquaculture industries, the demand for pelleted feed is also increasing. The influence of the material base temperature on the moisture absorption of steam-conditioning is enormous. If the base temperature of the mixed material is too high, steam tempering will be affected to a great extent, and the water content of the mixture will change at different times of the year, it has a significant effect on steam tempering. 1~10 tons of WNS series condensing gas-fired boilers of ZOZEN boiler are widely used in the feed industry due to its advantages such as high efficiency and high quality steam. Therefore, the Changzhou Gehu Feed at the time of initial construct plant ordered a one-ton WNS condensing gas-fired boiler at the ZOZEN in accordance with the plant scale to provide high-quality steam to participate in the production work.
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
Shandong Luhua Group Co., Ltd. is a large-scale private enterprise and a key leading enterprise of agricultural industrialization. It has 24 production bases and spans industries such as edible oil, condiments and vegetable processing. The annual production capacity of edible oil is 1 million tons, and the annual production capacity of condiments is 100,000 tons.
ZOZEN boiler Technical Team has customized various models and parameters of thermal oil heater according to the actual conditions of Fuxin Oil Plant. The person in charge of the project said that a total of YQW-14000Q, two YQL-105000Q and one YQW-4200Q thermal oil heater have been installed in the boiler room of the Fuxin Oil Plant of Luhua Group. Their rated thermal power is 12 million kcal, 900,000 kcal, 3.6 million kcal, which meet the edible oil processing drying / cooling - hot air frying - suction cooling - rolling crushing / peeling - steaming and other cumbersome production processes.
The thermal oil heater
Baoding Huakang Paper Co., Ltd. was founded in 1999 and covers an area of 90,000 square meters. It has five modern production lines and an annual output of over 100,000 tons. It has been developed into a large-scale paper company integrating product development, production and sales. With the increasing development of Huakang Paper, in the face of growing demand for paper products, they chose to cooperate with ZOZEN boiler. Huakang Paper purchased an SZS Series 20-ton condensing gas-fired steam boiler from ZOZEN boiler in 2017 for disinfection and sterilization in the manufacturing process of household paper.
Baoding Dayi Paper Co., Ltd. is located in Wangjiaguan Industrial Park, Shunping District, Baoding City, Hebei Province. The company covers an area of 5.33 hectares. At present, the company mainly has "Baihui", "Daiyi" two major brands, products for toilet paper roll, facial tissue, handkerchief paper, napkins and other series of living paper. Because Dayi uses 100% importing raw wood pulp as raw materials, the production of paper products must be sterilized at high temperatures. Therefore, Baoding Dayi Paper chose to cooperate with our company. Our company SZS series 20 tons of condensing gas-fired steam boiler owns many advantages, like full combustion of fuel, high efficiency, low energy consumption, clean and non-polluting. Its high-temperature steam generated through the conversion of energy, it help Dayi Paper achieve a variety of technological purposes such as cooking and drying.

Huagang Biological Feed Company was established in 2015 and is mainly engaged in feed processing and sales. Due to production needs, Huagang Biofeed added a 4-ton biomass-fired boiler to the plant to provide stable heat energy for drying feed. DZL series biomass-fired boilers are designed by ZOZEN and Shanghai Jiaotong University based on various biomass fuel characteristics and burning rates, and designed through numerical simulation, rational arrangement of furnace arches, furnace walls, and furnace heat receiving surfaces. In the production of biological feed in China and Hong Kong, there will be a large amount of crop residues, and ZOZEN proposes to use these residues as fuel for biomass-fired boilers. Compared with conventional boilers, the DZL series biomass-fired boilers have a large space in the furnace. At the same time, a very reasonable secondary air is arranged to make fuel fully burned, effectively reducing NOX emissions. The speed control box is configured for it, and the
