The drying, rolling and vulcanization processed of production in rubber industry are all need large amounts of steam. Dongrun Special Rubber & Plastics Co., Ltd. is one of the most professional industrial rubber production bases in the country. It produces special rubber sheets, rubber sheets for industrial use, anti-skid fitness series and rubber seals for sluice gates. It has complete specifications and over 10,000 varieties. This time we are particularly in purchasing boiler, especially the steam boiler efficiency, Dongrun put forward very strict requirements. ZOZEN boiler manufactures a 4-ton DZL coal-fired steam boiler for Dongrun. The boilers belong to the horizontal three-pass water-fired-tube chain grate boiler, which can use mean-quality bituminous coal and anthracite. Threaded tobacco pipe is also a high-efficiency heat transfer element researched by ZOZEN for many years. Its heat transfer coefficient is 1.8 times higher than that of ordinary tobacco pipe.
Yuanda Cable Co., Ltd.---a high-tech company specializing in the research, product and sale of power cables, branch cables and computer cables. The cable manufacturing process includes three processes of mixing, extruding and vulcanizing. During the extrusion process, overheating easily leads to scorching, when the temperature is too low, it’s hard to gel. In the vulcanization process, bubbles are easily generated when the temperature is too low or too high. The temperature and pressure requirements of every process are different, so the control of cooking temperature and pressure must be precise and adjustable. In 2011, Yuanda Cable had customized a 4-ton DZL coal-fired steam boiler at ZOZEN. This series carried out comprehensive safety monitoring of the boiler’s water level and steam pressure, and it used boiler safety control technology that complied with EU coal-fired boiler standards to ensure boiler operates safer and more reliable. The automatic and interlocking control technolo
Harbin Pharmaceutical Group Pharmaceutical Factory is a key antibiotic production base in China and a national large-scale pharmaceutical company. Pharmaceutical production companies cannot do without steam boilers. Nowadays, haze weather is serious and the country has strict standards for boiler emissions. When selecting the boiler, Harbin Pharmaceutical Group chose the SZW series of coal-fired steam boiler with compact structure and reasonable layout. This type of boiler has large water capacity and strong load adaptability. It is burned in a mechanized grate and burns in layers. It has good fuel combustion effect and high thermal efficiency. The product technology, performance, environmental protection indicators of ZOZEN boiler have reached the international advanced level. The person in charge of the company stated that the products of ZOZEN boiler provide practical and effective solutions for the environmental protection issues in the pharmaceutical industry.
The gas-fired replace coal-fired heating project is one of the decontamination projects to improve air quality in Tianjin. As a result, the fifth gas-fired replace coal-fired boilers project in Tianjin city center ware launched.
First, the coal-to-gas conversion project of the Tiantuo Heat Source Plant in Nankai District. The Tiantuo plant is surrounded by empty land to be built. The project plans to dismantle the original 3 sets of 58MW, 2 sets of 29MW coal-fired hot water boilers and 3 sets of 14 MW steam boilers. They build a new gas-fired boiler room on the west side of the existing boiler room, and install 10 sets of 29MW gas-fired boilers with auxiliary equipment, the heating area is maintained at 3.5 million square meters. Through vigorous bidding campaigns, ZOZEN provided 5 sets of 29MW gas-fired hot water boilers (SZS-1.6/130/70-Q) for the Tiantuo Heating Plant with advanced technology and strength in the boiler industry.
Second, Hedong District also undertakes the task of
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
Zhejiang Huadi Textile Printing & Dyeing Co., Ltd. is a professional home textile dyeing and printing company. It covers an area of 140,000 square meters, a total construction area of 160,000 square meters, under the chemical fiber dyeing, printing, cotton dyeing, printing, knitting dyeing, printing three plants, owns first-class dyeing printing equipment in the world introduced from Italy, Germany, Austria, Switzerland, South Korea and other countries, aims to create a first-class home textile fabric processing base. The high energy consumption processes such as water washing, dyeing, printing, and post-finishing required for the production of Zhejiang Huadi textile printing and dyeing enterprises need to be carried out at high temperatures. The thermal oil heater is an indispensable heat source device in the process. As the company's previous related equipment has not reached the ever-growing production demand, the YY (Q) W-4600Y (Q) horizontal gas-fired thermal oil heater produc
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.
