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
ZOZEN ZZ series mid-temperature and mid-pressure boiler has advantages of wide fuel adaptability and high combustion efficiency. Meanwhile, ZOZEN technicians scientifically designed the boiler system according to the actual needs of the production lines of Rashid Paper Mills Ltd. This ZZ series coal-fired boiler adopts a wide-coal-type furnace arch design to increase the furnace temperature. At the same time, isobaric storehouse draught and micro-zone air distribution are designed to reduce the carbon content of the slag, which improves the overall combustion efficiency. In addition, this series of boiler is a field-assembled boiler which has high requirements for the technicians and installation staff. In order to ensure the smooth completion of the project, ZOZEN technicians provided effective on-site guidance for Rashid Paper Mills Ltd. After the boiler is entered the commissioning stage, ZOZEN will also provide users with professional training from boiler working principles and ope
As a well-known industrial boiler manufacturer, ZOZEN focuses on the research and development of energy-saving technology. In order to help Hongda Textile to reduce energy consumption, ZOZEN customized the WNS series gas-fired boiler system according to the actual requirements of its production lines. Through the application of several patent technologies, this series of boiler has truly realized energy saving and high efficiency in terms of combustion efficiency, exhaust gas temperature, etc. Equipped with an advanced burner, the WNS series boiler realizes reasonable air distribution. Meanwhile, the large-diameter corrugated furnace of ZOZEN WNS series gas-fired steam boiler not only increases the heating-transfer surface but also ensures the full combustion of fuel, which increases the efficiency and reduces the consumption of fuel. In addition, ZOZEN adopts the patented condensing technology, which can fully absorb the waste heat of the exhaust gas, improve the water inlet temperatu
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.
With a large flow of tourists, Zhengzhou Railway Station is one of the eight transportation hubs in China. It is known as the heart of Chinese railways. The comfortable waiting environment comes from stable heating system. It is Zhengzhou Heating Company Second Road Heat Source Factory that provides stable heat source for Zhengzhou Railway station. Founded in 1989, the heat source factory was put into operation in 1992. In recent years, with the aging of old boilers, the thermal efficiency of the existing 4 sets of 20 tph chain grate steam boilers has been gradually reduced. Besides, considering environmental protection and other factors, Second Road Heat Source Factory decided to implement the Coal-to-Gas Project, dismantle the existing low-efficiency and high-consumption coal-fired boilers, and introduce some sets of SZS series gas-fired steam boilers.
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
