Qinghai Salt Lake Hainer Chemical Co., Ltd. is a wholly-owned subsidiary of Qinghai Salt Lake Industry Co., Ltd., and it is the first domestic company with a full set of advanced production equipment for PVC production technology and downstream product development capabilities. Qinghai Salt Lake Chemicals requires large quantities of steam in the production of PVC, which consumes a lot of fuel costs each year. The person in charge learned through multiple parties and contacted the ZOZEN boiler and purchased two 35T/h SHX series circulating fluidized bed steam boilers at ZOZEN. The boiler has an evaporation capacity of 10~75T/h, a steam pressure of 1.25~2.5MPa, a steam temperature of 194~225°C, a wide fuel adaptability and a high combustion efficiency. It not only can help Qinghai Salt Lake Chemical Company reduce the fuel consumption of several million yuan, but also significantly reduce the annual electricity consumption, its energy saving effect is very significant.
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
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.
Henan Wugu Spring Wine Co., Ltd. is a medium-sized professional liquor production enterprise controlled by Wuliangye Group. In 2016, with the increasing awareness of environmental protection in China, a considerable number of local governments have limited the use of coal-fired boilers. Where environmental protection policies are more demanding, wineries must use gas-fired steam boilers. ZOZEN boiler is a “AAA grade” credit rating company. In order to meet the service needs of the majority of companies, ZOZEN has established more than 30 offices throughout the country, providing a large number of boilers for many industries. In this project, ZOZEN provided a 6-ton WNS condensing gas-fired boiler according to the actual needs of Wuguchun liquor, and now the annual production capacity of Wuguchun liquor reaches 32,000 tons.
In recent years, the feed industry in China has developed rapidly, the scale of enterprises has been continuously expanded, production capacity has been greatly improved, and the number of newly-built plants and reformed old plants has increased. Jinyang Feed is the first specialized, industrialized, large-scale and standardized producer of rabbit feed in Sichuan Province. For a long time, it has devoted himself to the research and development of high quality rabbit feed. Although feed formulations have the greatest impact on particle quality, steam conditioning can play a greater role on the basis of formula. In view of the importance of steam in feed production, Jinyang Feeds has communicated with ZOZEN sales personnel several times, stating that rabbit pellet feed needs saturation dry steam pressure between 0.35~0.45MPa, and finally decided to order one set of 2 tons of WNS condensing gas boiler. ZOZEN boiler have been tested for energy efficiency by the Special Testing Institute T
Dongfang Xunchen is committed to thermoelectricity, thermal, energy conservation and environmental production industry. The company’s main business covers the energy-saving and transformation of thermoelectric and thermal project, and provides distributed energy services project for towns. This time, Shanxi Huiyuan Juice needed steam for ultra-high temperature instantaneous sterilization and aseptic cold filling for steam cracking and concentrated fruit juice production. It cooperated with Dongfang Xuanchen to provide thermal project services. The WNS series gas-fired boilers of ZOZEN they purchased add a condenser to the tail of the flue. The waste heat in the tail gas of the boiler is used to increase the boiler inlet temperature. The thermal efficiency of the boiler is as high as 98%, which saves a lot of operating costs for company. Dongfang Xuanchen and ZOZEN decide through consultation that two 10-ton WNS condensing gas-fired boilers will be installed for Shanxi Huiyuan Juice.
The rubber production of the outer layer of the wire and cable must undergo a vulcanization process, and the vulcanization process need the steam from boilers to heat and pressure the rubber. Anhui Cable is an enterprise specializing in the production of wire and cable. It mainly produces and operates 1E class K2, K3 and non-1E medium voltage power cables, various types of flame retardant and refractory special cables. In 2015, the principal of Anhui Cable purchased a 4-ton SZS Condensing Gas Fired Boiler in Zozen Boiler to provide steam for rubber vulcanization. The steam temperature was required to be between 140-180℃. After vulcanization, the natural cooling was performed, opened the valve, the steam condensate in the pipeline will go directly into the cooling pool. After steam cooling, fresh water can be added to the processed of drawing, annealing, ,water sealing, extruding, extruding rubber, mixed rubber, desulfurization and dust removal, which saves a lot of production water for
Shandong Luhua Group Co., Ltd. is a large-scale private enterprise and a key leading enterprise of agricultural industrialization. It has 24 production bases and spans industries such as edible oil, condiments and vegetable processing. The annual production capacity of edible oil is 1 million tons, and the annual production capacity of condiments is 100,000 tons.
ZOZEN boiler Technical Team has customized various models and parameters of thermal oil heater according to the actual conditions of Fuxin Oil Plant. The person in charge of the project said that a total of YQW-14000Q, two YQL-105000Q and one YQW-4200Q thermal oil heater have been installed in the boiler room of the Fuxin Oil Plant of Luhua Group. Their rated thermal power is 12 million kcal, 900,000 kcal, 3.6 million kcal, which meet the edible oil processing drying / cooling - hot air frying - suction cooling - rolling crushing / peeling - steaming and other cumbersome production processes.
