As the determination of country to prevent and control air pollution is increasing, various policies have been introduced across the country. Almost every region, the time period and number of boiler renovations have been issued. In order to maximize the cost savings of the company’s operations, most companies will choose to convert coal-fired boilers to gas-fired boilers, and the rubber chemicals industry is no exception. With the increasingly stringent policies and regulations being promulgated in succession, in 2013, Huasheng rubber planning rubber auxiliary energy-saving renovation project, they purchased a 10-ton WNS condensing gas-fired steam boiler at ZOZEN boiler. The condensing boiler is a hull-type three-way pyrotechnic tube structure researched and developed based on the mature technology of the current gas boiler, the heat load of the boiler is low. An additional condenser is installed at the tail of the flue to increase the boiler inlet temperature and reduce the temperatu
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
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
