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
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
The development of technology and the progress of skill require the diversification of the quality of the sodium sulfide. Enterprises must produce different types of sodium sulfide according to different users. Taihua Industry is high-tech chemical enterprise. Its main products are pure benzene, toluene, p-tert-butyl benzoic acid, industrial sodium sulfide, anhydrous crystalline sodium sulfide and nine-hydrate crystalline sodium sulfide. The production of sodium sulfide requires high temperature and stable steam. Therefore, Taihua Industry has conducted an inspection of the same industry manufacturers and combined with actual conditions of the unit to transform the caustic soda production system in the evaporation section. At first, Taihua purchased a 2.4 million thermal oil heater at ZOZEN(YY(Q)W-2800Q) to improve utilization rate of heat energy. Later, in order to increase the coal utilization rate, Taihua purchased a 2.4million kcal thermal oil heater(YLL-2800MA(w)) at ZOZEN
The processing and production of agricultural and sideline products, which involves dehydration, drying, refrigeration, freezing, salting and other technical processes, they all need a large amount of steam. Usually, such food companies purchase high-efficiency high-pressure steam boilers. As a long-established brand enterprise that pioneers the “new era of peanut leisure”, its main business is: sapid peanuts, sesame oil, chili power and snack food. After a period of investigation and comparison, the principal of the company chose to purchase two sets of horizontal gas-fired thermal oil heater(7 million kcal) at ZOZEN, which according to calculate the amount of steam used in production and processing of the products. The boiler of ZOZEN utilizes the high-temperature characteristics of the thermal oil heater to support low-pressure and high-temperature heat, can use a closed or opened circulate system according to the needs of users.
In the process of tire manufacturing, rubber mixing and vulcanization are two indispensable processes. Many tire factories generally build or use heating boilers of other companies in order to provide high-temperature steam for tire vulcanization. In order to meet the needs of production, Sentury Tire (Thailand) Co., Ltd. believes that the SZL series biomass-fired boilers of Zozen Boiler are superior to those of other companies in terms of fuel efficiency and energy saving. At the same time, the ZOZEN technical team also designed a speed control box with a reasonable speed according to the burning rate, and established different numbers of independent wind bins according to different tonnages to ensure that the fuel is fully burned. In the end, Sentury Tire (Thailand) Co., Ltd. purchased 2 sets of 20 t/h biomass-fired steam boilers at Zozen.
Ainengju Photovoltaic Technology Co., Ltd. is a science and technology development enterprise that integrates production, sales, and technology development. It has a total investment of 650 million yuan. It plans to invest in and construct an "annual production of 200MW polysilicon solar cell" project. This project has passed the environmental impact assessment test. ZOZEN's DZL series biomass-fired boilers are horizontal three-pass firepower pipe chain grate boilers. The boilers are quickly assembled and shipped from the factory. They have high combustion efficiency, sufficient steam output and less infrastructure investment. In order to improve the final product quality, photoelectric conversion efficiency, and efficiency of overall production line. To reduce the production cost, Aineng Photovoltaic Co., Ltd. order a 4-ton DZL biomass-fired steam boiler, which is used to produce configure crystalline silicon solar cells and battery modules.
Biomass-fired boilers are jointly developed and manufactures by ZOZEN boiler and Shanghai Jiaotong University. According to the fuel characteristics and combustion rate of various biomass-fired boilers, furnace arches, furnace walls and furnace heating surfaces can be rationally arranged to ensure high combustion and evaporation. Junhun Property mainly manages property management, house leasing, landscape afforesting design and construction, etc. In order to improve the heating quality of the community, Junhun purchased a 10t DZL series biomass-fired steam boiler (DZL-1.25-T) at ZOZEN. The fuel of biomass-fired boiler has wide adaptability and long service life. It is also recognized as a high-efficiency, energy-saving and environmental boiler product. At the same time, the input cost of biomass energy is relatively low, so biomass-fired boilers are widely used in urban industrial parks to meet the heating needs of the park.
