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%.
Confronted with the increasingly severe environmental protection policies, ZOZEN has made progress in the research and development of technologies in recent years. WNS series gas-fired boilers with features of high efficiency and low emissions are preferred by the industrial boiler market. This series of boiler adds a radiant heating surface to increase the heat transfer coefficient. Besides, the boiler adopts high-efficient threaded flue tubes to slow down the flue gas flow rate and fully absorb heat. In addition, energy-saving devices are equipped at the tail of the flue to increase the thermal efficiency to above 98%. The efficiency is superior to level 1 national energy efficiency standard. Moreover, the advanced low NOx burner greatly reduces the emission of NOx to 30 mg/m３. The ultra low emission provides guarantees for clean production and sustainable development of enterprises.
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.
Founded in 1994, Harbin Investment Group Co., Ltd. is mainly engaged in production and supply of electricity and heat. The SZS series gas-fired package boiler purchased by public bidding performed well both in environmental protection and thermal efficiency. Adopting D-type arrangement and water tube structure, the boiler is equipped with a big combustion chamber for the full combustion of fuel. Advanced low NOx combustion technology is combined to reduce the
NOx emission to 30mg/Nm3. Combustion chamber is designed with narrow distance full membrane water cooling wall which has good air proof and high thermal efficiency. Meanwhile, the flue gas condensers equipped at the tail of the boiler can effectively control the flue gas temperature, increasing the thermal efficiency of the boiler to over 98%. Besides, the package delivery feature of SZS series gas-fired boiler greatly reduced infrastructure cost
Founded in 1818, Libbey Inc. is a large manufacturer of glassware and it is also the standard maker of catering glassware industry in North American. With over 1 billion annual output value, Libbey operates 6 glass manufacturing factories in 5 countries on 3 continents. Libbey (China) Co., Ltd. was set up to develop the Asia-Pacific market. The glass tableware factory located in Langfang Hebei Economic and Technological Development Zone was put into production in early 2007. Its production capacity was up to 100 million per year. As a global company adhering to sustainable development, Libbey decided to update the existing gas-fired boilers to achieve low NOx emissions.
In recent years, the demand for rubber chemicals has greatly increased due to the rapid development of the rubber industry. The industrial boilers play an important role in providing heat source for the production process of rubber chemicals. Shandong Dyrike New Materials Co., Ltd., invested by Shandong Yanggu Huatai Chemical Co., Ltd. Is the leading enterprise of rubber chemical industry, the listed enterprise and the national high-tech enterprise founded in 2010 with a total investment of 450 million yuan. Specializing in the production of rubber vulcanization accelerators, rubber anti-scorcher, rubber chemicals and other green chemicals. Dyrike cooperates with Michelin, Bridgestone, Pirelli, Continental and other well-known tire companies and has a good market infrastructure and prospects.
ZOZEN has been implementing the Belt and Road initiative all the time. Qingdao United Zhenye Energy Saving Technology Co., Ltd carried out an in-depth cooperation with Kazakhstan on environmental protection technology of oil fields. ZOZEN provided stable and efficient thermal energy for the project. The first batch of YQW series thermal oil heaters and WNS gas-fired steam boilers has been delivered to Kazakhstan. It indicated that ZOZEN has got the affirmation of users in Kazakhstan again.
The automobile has brought convenience for people's travel. The steam boiler is one piece of the indispensable equipment in the modern automobile production line. As we all know, Geely Auto is one of the top ten enterprises in China's automobile industry. It has achieved rapid development by virtue of its flexible operation mechanism and continuous independent innovation since it entered the field of automobile in 1997. As a first-class manufacturing subsidiary of Geely, Zhejiang Land Rover Automobile Co., ltd decided to expand the Linhai industrial park to produce 300,000 vehicles and key components annually. During the construction of the industrial park, Geely Auto conducted an open bidding and planned to introduce a batch of steam boilers with excellent performance in all aspects.
