Hohhot Huaou Starch Co., Ltd, established in 1992, is a large-scale potato furthering processing enterprise in China, whose potato starch possesses excellent whiteness, viscosity, clarity, gelatinization temperature and is widely applied. In the processing of potato starch, steps like dehydration and drying decide the quality of potato starch. Therefore, steam boiler with high output and efficiency plays an essential role in the enterprise's production. After a series of market investigation, Hohhot Huaou Starch Co., Ltd decided to purchase two sets of ZOZEN WNS series gas-fired steam boiler as the heat supply for its production line.
After having an in-depth understanding about the industrial boiler market, Yushuwan Coal Mine selected ZOZEN as its boiler equipment supplier. ZOZEN provided a scientific and reasonable boiler solution for Yushuwan Coal Mine including multiple sets of gas-fired steam boilers. The boiler solution not only can meet the requirements of production and living, but also can improve the utilization rate of thermal energy. Meanwhile, every ZOZEN gas-fired boiler adopts a low NOx burner to meet the low NOx emission requirement. In addition, the utilization of staged combustion technology greatly reduces the generation of NOx. And, the flue gas NOx content showed in the third-party EIA test is 14-17mg/m3. The value is far lower than the environmental protection standard of 30mg/m3.
This series of circulating fluidized bed is low-temperature combustion. It can desulfurize directly during the combustion process. Besides, the technology and equipment are simple and economic, and the desulfurization efficiency is high. Meanwhile, high temperature cyclone separator in combination with the design of big furnace and low flow rate prolongs the time of coal particles stayed in the furnace, which can ensure complete combustion of coal and effectively improve the thermal efficiency of boilers. In addition, multiple baffle plates are designed on the convection heating surface, which increases the flue gas flow and reduces the dust. Moreover, serpentine tube economizer and air preheater further improve the overall thermal efficiency of the boiler to more than 89%.
This time, Jilin Deda purchased a branch of ZOZEN WNS series gas-fired boilers for demands of meat production and workers' heat supply. This type of gas-fired steam boilers adopts horizontal internal combustion wetback structure with novel design and rational structure. The burner flame is burning in large-diameter corrugated furnace in slight positive vacuum condition. It combined with high-efficient threaded smoke tubes and scientific furnace heat preservation design that can effectively improve thermal efficiency to more than 98%, which is superior to the national Level 1 energy efficiency standard and can realize the expected energy-saving goal of Jilin Deda. Besides, the advanced automatic control system can realize automatic start-stop, load adjustment, water supply and other operations according to the demands of users. With features of easy operation and low failure rate, the control system is both safe and reliable.
For a long time, steam boilers have played an indispensable and important role in the production lines of various feed enterprises. Established in 1996, Guangdong Yuanxin Feed Industry Co., Ltd. is a company integrating R & D, production and sales of livestock, poultry, aquatic products and bullfrog feed. With the rapid development in recent years, the market share of Yuanxin Feed has continued to expand, and the company needed to purchase new steam boilers to meet the actual needs of the production line. Based on the mutual understanding and trust, Yuanxin Feed purchased boiler equipment again from ZOZEN on the SZL series chain grate steam boiler.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
Charoen Pokphand Group is a well-known multinational company founded by a Thai Chinese, also known as the CP Group, its output value and scale are both the leaders of the industry. In 2016, CP Group invested Jilin Chia Tai Food Co., LTD. to expand its scale, which has an annual processing capacity of 100 million broilers. During the processing of broilers, whether the disinfection & distillation, baking & stewing, or heating & drying, the heat source provided by the the steam boiler is required. In order to purchase a set of high-performance and low-emission boiler, CP Group carried out a public bidding.
The dyeing auxiliary is a chemical which enables a processing operation in textile preparation, dyeing, printing or finishing to be carried out more effectively, a boiler provides stable heat source for its production process. Wuxi Kailai Biotechnology Co., Ltd., established in 2001, is an enterprise specializing in developing and manufacturing textile dyeing auxiliaries. The improving performance requirements for textiles lead to a largely increasing demand for dyeing auxiliaries. Kailai Biotechnology decided to obsolete the backward productivity due to the need of enterprise's own development as well as complying with the policy requirements of environmental protection, Kailai Biotechnology planned to order one set of 1.8 million Kcal thermal oil heater and use clean energy natural gas as boiler fuel.
As one piece of important equipment of the production line, the thermal oil heater has a direct impact on the quality of dyeing auxiliaries and the benefit of the whole enterprise.
