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
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
Vinda Group is a large-scale modern paper enterprise that integrates research, development, production and sales. The products are exported to Europe, America, Japan, Australia, New Zealand and Southeast Asian countries. Vinda long-term adherence to environmental protection and energy conservation and the mission of bringing clean and comfortable domestic paper to humanity coincides with our corporate goals of protecting the environment and saving energy. In 2011, the second phase of Vinda Paper Sichuan Branch was completed. They chose to cooperate with ZOZEN boiler. The technicians of ZOZEN boiler recommended a 15-ton WNS15-1.25-Q condensing gas-fired steam boiler according to environmental standards and production efficiency. Compared with coal-fired boilers, WNS series boilers use cleaner and more efficient fuels, have better energy-saving and emission-reduction effects, and can meet environmental protection requirements. At the same time, the size of the furnace of the WNS series b
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 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.
Pharmaceutical production companies are inseparable from steam boilers, and Jiahe Pharmaceuticals is a modern pharmaceutical company integrating pharmaceutical production, sales, and research and development. In recent years, R&D investment in technology innovation has been continuously increased. In terms of boiler room renovation, Jiahe Pharmaceutical has learned that ZOZEN boiler is the first business in China to use an arched tube plate and a threaded tobacco pipe structure to increase honduction and completely solve the problem of cracking of the rear tube plate. From the aspect of making boilers, Jiahe Pharmaceuticals has decisively selected the "Zozen Brand" 4-ton biomass-fired steam boiler (DZL4-1.25-T). The boiler is a horizontal three-pass water-fire pipe chain grate boiler with compact structure and simple size. After the completion of the transformation, it is expected that Jiahe pharmaceutical company will achieve leapfrog development in the next few years.ZOZEN
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
