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
The 154th Central Hospital of the Chinese People's Liberation Army is a tertiary hospital that integrates medical treatment, teaching, and research. With the continuous expansion of the hospital scale, the increase in the number of beds, departments, and trainees, the boiler evaporation capacity of the original boiler room is too small to meet the sterilization and disinfection, sanitary hot water preparation, hospital laundry and so on. In 2012, the 154th hospital changed its boilers and ordered a 10-ton SZL coal-fired steam boiler for use in the hospital. In recent years, under the increasingly severe atmosphere situation of the whole country and the province, environmental problems have become increasingly prominent. Xinyang has issued the “Implementation Plan for Suppressing Coal-fired Boilers in Xinyang City from 2014 to 2017”. In 2016, the No.154 Hospital as a national tertiary general hospital, actively responded to the call for environmental protection, and implemented replacem
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
Shijiazhuang Harmonious Paper Co., Ltd. is an old enterprise in the papermaking industry specializing in the production of high-strength corrugated base paper. At present, it has a number of advanced papermaking equipments, which integrates many years of production experience. It produces 60,000 tons of high-strength corrugated base papers and sells well in Beijing, Tianjin, Ningbo and other places, and is well received by customers. At the same time, Harmony Paper is a key environmental protection project promoted by Hebei Province. In 2017, Harmony Paper introduced an SZS 20-ton condensing gas-fired steam boiler from our company. This boiler is characterized by energy saving, environmental, clean combustion, pollution-free emission and convenient operation. Helping Harmonious Paper to transform quality products and serve society.
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.
