ZOZEN has been a leading industrial manufacturer after more than 30 years of development. In recent years, with the increasingly strict environmental protection policies, ZOZEN has intensified great efforts in the research and development of gas-fired boiler products and improving the environmental performance and overall thermal efficiency of boilers. As a star product of ZOZEN environment-friendly boiler, the WNS series gas-fired boiler adopts an advanced low NOx burner. In addition, ZOZEN optimizes the design of furnace size, volumetric heat load, and the flue gas flow rate of the convection area to ensure that the NOx emission is less than 30mg / Nm3. In terms of improving the thermal efficiency of the boiler, ZOZEN adopts threaded smoke tubes to enhance the heat transfer effect. Meanwhile, through the application of condensation technology, the sensible and latent heat in the high-temperature flue gas can be fully absorbed, which can increase the inlet temperature and improve the
With features of low pressure and high temperature, ZOZEN various series of thermal oil heaters have become heat source of many chemical enterprises. ZOZEN YLW series coal-fired(biomass-fired) thermal oil heater is a square coil horizontal chain grate shop-assembled heater of which the chain grate and heater proper are transported separately. Once connected the oil and electricity, the heater can be put in use. This series of heater adopts an advanced structure, including four parts: the radiation furnace heating area, convection tube bundle heating area, waste heat boiler and air heater, which has sufficient heating area and ensures high thermal efficiency of the boiler. Meanwhile, ZOZEN reasonably designed the combustion chamber according to different characteristics of different types of coal and biomass fuel, which not only ensures the complete combustion of the fuel but also improves the combustion efficiency and reduces the formation and emission of flue gas. This series of heate
In recent years, with the continuous advancement of the Coal-to-Gas policy, Tulufanbei Railway Station decided to introduce two sets of 2.8MW gas-fired hot water boilers, dismantle the existing coal-fired boilers, supporting facilities, draft fans and dust collectors and keep the existing water treatment equipment, circulation pump and feedwater pump in use. After having an in-depth understanding of the requirements of the customer, ZOZEN customized a high-efficient gas-fired boiler solution for Tulufanbei Railway Station. The WNS series hot water boiler recommended in the solution has outstanding advantages. With an automatic control system, the boiler can automatically realize operations such as start-stop, load adjustment, and water supply as the system required. Meanwhile, the large-diameter corrugated furnace of this series of boiler not only increases the heating area but also ensures the full combustion of fuel. In addition, equipped with an advanced low NOx burner, the boiler c
Known as "mirror of the sky", the Uyuni Salt Flat of Bolivia is a salt flat with the largest lithium reserves in the world. It is estimated that the lithium reserves of the Uyuni Salt Flat account for 70% of the lithium reserves of the world. The lithium industry chain market has huge potential and the abundant lithium resources also provide favorable conditions for Bolivia's economic development. To effectively promote the exploitation and utilization of the lithium resources of the salt flat, Yacimientos de Litio Bolivianos-YLB, a state-owned listed company of Bolivia, decided to build a new lithium carbonate plant. As an important piece of supporting equipment, the industrial boiler will provide a reliable heat source for the development and commercialization of the resources of the salt flat.
With outstanding product quality and environmental protection performance, ZOZEN has occupied a certain market share in the dyeing and finishing industry and has obtained a good reputation. ZOZEN SZL series biomass-fired boiler is an environment-friendly boiler that is jointly developed by ZOZEN and Shanghai Jiaotong University. According to different characteristics of biomass fuels and different burning rates, ZOZEN rationally arranges the heating area of the furnace arch, furnace wall and furnace to ensure the combustion efficiency and design evaporation. Meanwhile, after numerous experiments, ZOZEN rationally arranges the primary and secondary air, which can effectively reduce NOx emissions and ensure the fuel is fully burned.
During the production of Alpha GPC, the process of evaporation and concentration requires high temperature steam provided by steam boilers. In order to respond to the call of clean production, Foman Biopharma selected a set of ZOZEN boiler which used natural gas as fuel. Meanwhile, ZOZEN customized the WNS series gas-fired boiler solution according the actual steam needs of Foman Biopharma. This series of boilers are wetback fire-tube boilers. With a three-pass design, the boiler adopts a large-diameter corrugated furnace. A combination of threaded flue tubes and smooth flue tubes is designed to increase the flue gas flow and optimize the heat transfer effect.
Besides, energy saving devices are equipped at the tail of the flue to fully absorb the heat energy and improve the thermal efficiency of the boiler to more than 98%, which can reduce operating costs for Foman Biopharma.
This series of thermal oil heater can realize low-pressure and high-temperature heating by utilizing the characteristics of the thermal oil heater. The high thermal inertia can effectively maintain the temperature uniformity during the food heating process. This thermal oil heater has outstanding energy-saving effects and low operation costs. It adopts closed-loop circulating liquid phase to transfer heat energy, the heat loss of steam boilers such as heat running, dripping and leaking can be avoided. Meanwhile, a complete operation control system and safety monitoring devices are equipped to precisely control the working temperature. It was the mix of these advantages that effectively reduced the production costs and improved the production safety of Changling Food.
In the building material industry, the aerated concrete block is a new type of lightweight building material. With good thermal insulation properties and strong sound absorption effects, this kind of material has a broad market prospect. However, the formation of this porous lightweight aerated concrete block requires saturated steam. So, the steam boiler is very important for the production line. With advantages of energy saving and high efficiency, ZOZEN SZS series gas-fired boiler is preferred by the building material industry. The capacity ranges from 2-160t/h, and the working pressure is 1.25-5.3Mpa. This series of boiler adopts a large-volume combustion chamber. An automatic energy-saving burner is equipped to ensure the complete combustion of fuel and improve combustion efficiency. Meanwhile, the combustion chamber uses a narrow-pitch membrane wall, which has good air tightness, to reduce heat loss and improve combustion efficiency. In addition, the boiler adopts an explosion-pr
