For the steam system with high condensate recovery rate and high condensate return temperature, and users who have higher system energy saving requirements, Kenuo engineers design the Rear Air Preheating condensing steam boiler. the high efficiency air pre-heater plus the integrated economizer and condenser, further reduce the smoke exhaust temperature lowest to 60 degree C., it can greatly save energy and improve boiler thermal efficiency. This boiler adopts the Surpass traditional two pass (high efficiency and low stress) fully wet back boiler body structure, arc-shaped double-open furnace door for easy maintenance. Equipped with high-efficiency air preheater, low-resistance airfoil economizer and condenser, the sensible heat and latent heat of vaporization in flue gas are recovered to the maximum extent. Boiler thermal efficiency can be up to 103%.
With the development of modern industry, the clients have higher standards for the equipment and products. To satisfy the demands of the customers, the product designer engineers of Kenuo designed and launched the latest type of post-air preheating condensing steam boiler. Post-air preheating steam boiler is aimed at the steam system with a high condensate recovery rate and condensate return temperature, and it is the perfect equipment for users with higher system energy-saving requirements. Moreover, the post-air preheating boiler contains the latest technology and the most advanced auxiliaries, which is the ideal steam boiler machine for industries seeking reliable, energy-saving steam production.
Kenuo’s Ultra-Low NOx Condensing Steam Boiler (Post air Preheating) adopts horizontal wet back internal combustion flue gas two-pass structure with high efficiency and low stress as its main body. The most striking point of this industrial steam boiler machine is the recovery of the condensate water, which is the key to the improvement of thermal efficiency. The air preheater is an integrated component located at the exhaust end of the boiler system.
The main structure can help the steam boiler to capture latent heat in the flue gas to preheat the combustion air. This excellent configuration enhances overall boiler thermal efficiency and lowers fuel consumption. By fully utilizing the heat of the steam boiler, the equipment not only improves the working efficiency but also helps reduce the emissions of nitrogen oxide. With the assistance of industrial steam boilers, industries can enjoy higher productivity and lower operational costs.
Industrial boilers are significant equipment in modern manufacturing. To learn more about the industrial steam boiler, understanding how a boiler works is essential for selecting the right boiler and optimizing performance. The working principle of the industrial steam boiler can be divided into two circulations.
The combustion of the fuel in the furnace produces a great deal of heat energy. Through the heat exchanger, the heat can raise the temperature of the water in the boiler. By keeping heating the water in the boiler, steam with high temperature and high stress can be produced. Then, the steam gets distributed by the steam drum for industrial use or daily use.
With the combustion in the furnace, the boiler produces the high-temperature flue gas. The produced flue gas enters the thread smoke pipes after flowing out of the reversal chamber. After the highly efficient heat exchange, the flue gas gets into the air preheater through the front smoke box. The temperature of the cold air rises by the counter-current heat exchange. Cooling flue gas flows into the economizer and condensing machine to recover the sensible heat and latent heat. The recovery heat can be reused to preheat the feed water temperature of the boiler. When the heat of the flue gas fully recovers, the waste flue gas exits from the chimney to the air.
When it comes to efficient and reliable boiler operation, it’s not just the main body of the boiler machine that matters. The quality and configuration of its accessories play a crucial role as well.
Rear positioned air preheater is the latest product innovated by Kenuo. The post-air preheater uses a two-way counterflow heat exchange mode to realize a bigger temperature difference to raise heat exchange efficiency. Even at a rather low temperature, the post-air preheater still can be activated easily. Therefore, the air temperature can increase instantly. What’s more, the boiler auxiliary can accelerate combustion and the combustion efficiency can be up to 99.99%. The material of the air preheater is ND steel, which enjoys high heat exchange strength and strong corrosion resistance.
High efficient energy-saving and condensing machine is independently developed by Kenuo. In the manufacturing process of this part, the engineer adopts high-quality ND steel and magnesia aluminum silica alloy winding composite finned tubes. Great heat transfer performance and strong corrosion resistance are the outstanding features of the condensing machine. With a double energy-saving effect, the device can recover the sensible heat and latent heat to the maximum extent.
The variable frequency feed water system can automatically track the steam usage load and adjust the water supply. According to this system, the industrial steam boiler can realize a stable water supply. Variable frequency can not only keep the boiler water at a certain temperature, but also reduce the water fluctuation. This variable frequency feed water system can assist the steam boiler achieve stable steam stress and high steam dryness.
With all the advanced technologies and excellent design, the industrial boilers of Kenuo contain a lot of advantages compared to other brands. Due to the philosophy of putting the customer’s interest first place, Kenuo strives to innovate and develop the most advanced boilers to meet the customer’s demands.
High thermal efficiency is one of the key advantages of the Kenuo industrial steam boiler. A steam boiler with high thermal efficiency converts more fuel into usable heat, reducing energy waste and significantly lowering fuel costs. Choosing a high-efficiency industrial steam boiler machine means improved performance, faster steam generation, and improved overall productivity for your operation.
The combination of a large corrugated furnace and split burner of Cavallo can create a perfect circumstance to lower the emission of combustion. The LNZ-H series industrial steam boiler of kenuo can decrease the nitrogen oxide emission to less than 30mg/m³. Various combustion technologies can burn the fuel completely to save the operational costs.
The condensate is generated in the process of using steam, so the condensate water can be recovered after iron removal, oil removal, and other treatment. Then, the condensate is returned to the boiler as make-up water, and the heat and water resources of the condensate can be collected for further usage. This arrangement can save fuel by 5%-10% and reduce the operational costs.
When it comes to reliable, energy-efficient, and high-quality, Kenuo stands out as the trusted partner in the industry.
