From 2014, Baoji City began to implement natural gas projects and vigorously implemented coal-to-gas conversion projects. Baoji Cigarette Factory is one of the major backbone enterprises of the China National Tobacco Corporation and is the largest cigarette manufacturer in the northwest region. In line with the environmental protection policy, Baoji Cigarette Factory implemented the "coal to gas" project. Through bidding activities, it cooperated with ZOZEN boiler to dismantle 35 tons of coal-fired boilers and install 25 tons of SZS gas-fired steam boilers to improve boiler operation levels and reduce air pollutant emissions.
The "Golden Leaf Group" is one of the only listed companies in the country for tobacco. In 2010, Golden Leaf established a Good Cat Cigarette Company in Xian, which mainly produces high-grade cigarette pack printing and cigarette filter rods. Good cat companies need to use a lot of steam in combination with filter rod production, tobacco carton compounding, and drying. According to the requirements of the national environmental protection regulations, standards, environmental impact assessment technical guidelines and other requirements, the boiler was invited to bid. ZOZEN boiler had the honor to provide a 10 ton WNS condensing gas-fired steam boiler for production use. Vertical and circumferential seams of the boiler, ZOZEN are all using advanced submerged arc welding technology, and 100% ray detection to ensure the quality of welding. At the same time, the WNS series boilers are equipped with sufficient steam space and heating surface so that the boiler can efficiently produce high-
Xincheng Hotel is the first five-star hotel in Inner Mongolia Autonomous Region that integrates catering, accommodation, entertainment, and conferences. It has rooms, restaurants, bars, conference venues, theater shopping stores and National Travel Agency. Since its establishment, it has always been tasked with receiving party and state leaders, foreign heads of state, and important guests from all walks of life. In such large and important places, heating and sanitation water must be backed by boilers with excellent quality and safety in winter. After the bidding activities, Xincheng Hotel cooperated with ZOZEN boiler, and ZOZEN provided two 6-ton WNS condensing gas-fired boilers. The thread smoke pipes of this series of boilers are high-efficiency heat transfer elements that ZOZEN boiler has been researching for many years. When satisfying the minimum flow resistance, the heat transfer coefficient is 1.2 times higher than that of ordinary tobacco pipes when the thread groove depth
Luoyang Junshan Pharmaceutical Co., Ltd. is a modern pharmaceutical company mainly engaged in traditional Chinese medicine and natural medicine, integrating R&D, production, and sales. Traditional Chinese medicine pharmaceutical companies generally have extraction, concentration, distillation, drying, sterilization, purified water preparation, air-conditioning chillers and other technological equipment, all of which use steam as a heat source. However, at this stage, the general TCM companies do not use steam for comprehensive utilization. Steam is used only once, and a large amount of waste heat and waste heat are directly discharged into the atmosphere. The overall energy utilization rate is low. The person in charge of Junshan Pharmaceutical, through investigating and comparing the boilers on the market, finally chose to customize a 6-ton WNS condensing gas-fired steam boiler in the Zozen boiler to reduce boiler steam consumption and waste heat recovery, and increase the boiler ther
Jiangxi Copper Group is an ultra-large joint enterprise containing copper mining, selection, smelting in Chinese non-ferrous metals industry. It is also Chinese largest copper product production base and an important raw material for sulfide, and gold, silver and scattered metal producing area. As we all know, in the copper smelting process, a large amount of electricity and steam are consumed, and steam consumption accounts for about 30 to 40% of them. ZOZEN boiler has provided two 40-ton SZS condensing gas-fired boilers. The boiler adopts a D-type full-membrane wall structure, and the combustion chamber uses a narrow-pitch tube-type water wall, which has good sealing properties and reduces heat loss. The boiler body is made of high-quality aluminum silicate fiber and then kept in fire-resistant mud to keep the furnace temperature below 45°C and effectively control the heat loss.Luoyang Junshan Pharmaceutical Co., Ltd. is a modern pharmaceutical company mainly engaged in traditional C
Jiangsu SINOPEC mainly produces power cables, fire-retardant cables for coal mines, and various flame-retardant and fire-resistant special wires and cables. Wires and cables project production process requires a lot of steam, in which the extruder heating, mixing rubber equipment preheating process in the drive 1 ~ 2h need to use 0.3 ~ 0.4MPa low pressure steam preheating, cable continuous cross-linking process requires a pressure of 2.5MPa Steam as a heating medium. In recent years, through years of sustained and stable development, the company’s scale and overall strength have been continuously improved. In 2016, Jiangsu SINOPC replaced coal-fired boilers with gas-fired boilers. ZOZEN and Jiangsu SINOPEC are both in the beautiful coast of Taihu Lake. As we all know, ZOZEN boiler has advanced manufacturing technology and complete equipment, the service life of the boiler is very long. After the inspection at ZOZEN boiler, Jiangsu SINOPEC ordered two 6-ton SZS condensing gas-fired boil
ZOZEN boiler’s SZS series of condensing gas-fired boilers adopt double-drum ‘D’ type arrangement, whose structure is compact and floor space is small. The furnace adopts membrane wall structure, the seal between the membrane wall and pipes on both sides of the furnace adopts comb plate, to prevent leakage of condensate and gas. The boiler layout heating surface is large enough to design a large space for steam, to ensure that the boiler operates stably. Jiangsu Shangshang Cable Group is a professional manufacturer of wire and cable, focusing on R&D, manufacturing and services of wire and cable products. For the production needs, they want to expand the boiler room. The technical team of ZOZEN boiler has configured two SZS condensing gas-fired boilers, one 10 ton and one 6 ton, according to Shangshang’s boiler room area and the needs of steam during the production process. And ZOZEN’s steam meet the production requirements of the Shangshang cable.
Wandashan Dairy Industry, which is a holding company of Beidahuang Group, is equipped with 65 modern production lines and can produce nearly 200 varieties of milk powder, liquid milk, beverages, soy products, and rice products. The process of preheating, sterilizing, cooling and other processes of fresh milk requires a lot of steam. Because ZOZEN has provided their product into all walks of life and is one of the few boiler companies that holds a Class A boiler manufacturing license, Wandashan Dairy purchased two 20-tonne SZL coal-fired steam boilers at ZOZEN. According to the difference in coal quality and tonnage, independent wind storage can be set up to ensure the burnout of coal. Wandashan Dairy now processes 1 million tons of fresh milk annually.
