• Pre-air Preheating Condensing Steam Boiler

  In modern industrial production, the boiler plays a critical role in the thermal process. Due to the special features, boilers can be applied in various industries, including food processing, chemical, pharmaceutical, and other industries. With the increasing awareness of environmental protection and energy conservation, more and more enterprises are focusing on the efficiency and emission of the boiler. Kenuo is specialized in the design and development of industrial boilers. Pre-air preheating condensing steam boiler (LNZ-Q) is the version that combines cutting-edge technology and advanced technical ideas. The industrial steam boiler of Kenuo can not only improve production efficiency but also reduce operational costs.

• What is the Pre-air PreHeating Steam Boiler?

  The industrial steam boiler is used to transfer heat to water and the process can produce steam for a variety of applications. To meet market demands, our company keeps trying to innovate and improving the performance of the steam boiler. As a result, the Kenuo boiler is capable of producing many kinds of industrial boilers at a world-leading level. Pre-air preheating steam boiler represents a new achievement for innovation and development.

  Pre-air preheating steam boiler is the 6th generation of industrial steam boiler. The series of WNS-Q steam boilers enjoy advanced auxiliaries and precise design. As a combination of high technology and high quality, Kenuo’s pre-air preheating steam boiler is the perfect choice for industrial manufacturing.

• The Composition of the Steam Boiler

  In order to save energy and improve efficiency, Kenuo invents a unique system to improve thermal efficiency and narrow the occupied space. With all the suitable accessories, the pre-air heating steam boiler can get the best performance.

• Pre-air Preheater

   

  The WNS-Q(LNK) adopts a pre-air preheater to efficiently improve the performance of heat exchange and lower the consumption of energy. The air preheater can be easily started at a rather low temperature, heating up the air in a short time. With high thermal exchange and anti-corrosion ability, the combustion efficiency of the equipment can reach 99.99%. As for the steam boiler’s thermal efficiency, the value can be increased by 3%.

• Economizer and Condenser All-in-one Machine

   

  The main body of the economizer is made of ND steel and silicon magnesium-aluminum alloy finned tubes. These materials are perfect for the economizer and condenser because of their high heat transfer performance and anti-corrosion ability. The energy-saving and condensing system can recycle the sensible heat of the gas and the latent heat of the steam condensation. Therefore, the heat exchange can raise feeding water temperature and reduce exhaust temperature. The maximum efficiency can increase up to 103%.

• Large Corrugated Furnace

   

  The large corrugated furnace can create a larger combustion chamber to lower the flame temperature so that the equipment can guarantee NOx≤30mg/m³ emission. The special feature of the furnace assists the water in the boiler heating up evenly and makes sure the water level and pressure are maintained at a stable position.

  

   

  • The Working Principle of the Preheating Steam Boiler

    A steam boiler is a device that heats water and produces steam using fuel or other energy sources. During the whole process, every part of the boiler plays an important role in its position.
    In the first place, the Cavallo ultra-low NOx dual-bloc burner provides the flame that can make the fuel burn sufficiently. The large corrugated furnace is one of the most important parts of the boiler. The unique shape can increase the heating surface and reduce the drag. After the high-temperature flue gas enters the reversal chamber, a threaded smoke pipe collects the flue gas to carry out heat transfer. By exchanging the heat with the water, the cooler gas gets into the air preheater to raise the temperature of the air. Then, the flue gas flows into the economizer and condenser. During the process, the flow needs to get through the silicon-magnesium-aluminum alloy finned tube to recover the sensible heat and latent heat to increase boiler feed water temperature. When the heat recovery is finished, the flue gas exits from the chimney to the air.

    What makes Kenuo the leading boiler brand in China is that we introduce many advanced technologies and energy-saving concepts into the working processes to improve efficiency and reduce costs.

• Advantages of the Pre-air Heating Condensing Steam Boiler

  As China’s leading industrial boiler manufacturer, the products of Kenuo enjoy more advanced technologies than other brands. When it comes to the pre-air preheating steam boilers, the advantages are competitive enough to make Kenuo your best choice for industrial boilers.

• High Thermal Efficiency

   

  With the full utilization of sensible heat and latent heat, the performance of boilers embraces a new upgrade. The pre-air heating condensing steam machine designed and developed by Kenuo can improve the thermal efficiency by more than 6% higher than the traditional three-pass boilers. Each ton of steam can save 5Nm³natural gas. Clients can enjoy higher productivity and lower operational costs. The energy-saving concept is the reason why many clients choose to have faith in our products.

• High Steam Quality

   

  For a steam boiler, the steam quality is one of the most important parameters to assess the performance of an industrial steam boiler. Kenuo’s LNZ-Q series steam boiler can ensure the steam dryness fraction of up to 98%. With higher steam quality, the steam moisture content can be lower. The steam boiler can contain a higher water circulation ratio.

• Variable Frequency Combustion Technique

   

  The LNZ-Q series steam boiler adopts a Cavallo split burner to realize efficient combustion. Italy Cavallo ultra-low NOx burner has many combustion technologies, such as a three-stage fuel classification technology, four-stage air mixing technology, premixing technology, and FGR technology. Combining oxygen-excess combustion and oxygen-poor combustion can neutralize the flame temperature to decrease emissions of nitrogen oxide. With variable frequency combustion, the industrial steam boiler can achieve ultra-low nitrogen oxide emissions of less than 30mg/m³.
