In modern fertilizer production systems, the hot blast stove, as the core heating equipment, together with the rotary drum dryer and the burner, forms an efficient and energy-saving drying production line.
This combined system effectively solves the problems of moisture control and energy consumption during the drying process of organic fertilizers, bio-fertilizers and other products by stably providing high-temperature pure hot air.
The LANE hot blast stove adopts the industry-leading multi-head spiral groove plate heat exchange technology. It features a compact and reasonable structure, high thermal intensity, rapid temperature rise, and a significantly higher thermal efficiency than traditional equipment.
Customizable hot blast stoves can adapt to the layout of fertilizer production lines of different scales. From small and medium-sized organic fertilizer factories to large compound fertilizer production bases, matching solutions can be found.
In practical applications, the compound fertilizer factory in Africa with an annual output of 100,000 tons has successfully transformed from coal to biomass energy by adopting the LANE 1.2 million kcal hot blast stove in combination with a drum drying system. While ensuring stable production, the operating cost per hour has been reduced by 10 to 40 USD.

The LANE hot blast stove adopts a multi-layer sleeve structure made of all-steel plates, integrating the combustion chamber and the heat exchanger into one, achieving a compact and efficient layout design. The entire machine is mainly composed of seven core components:
This modular design enables the hot blast stove to be seamlessly integrated with the rotary drum dryer, allowing for rapid system integration whether it is a new production line or the renovation of existing equipment.
1. Environmental protection and safety performance
2. Intelligent control and stable operation
The LANE hot blast stove is equipped with an intelligent temperature control system, achieving full-process automated management:
These intelligent features enable the hot blast stove to operate continuously and stably for more than 8,000 hours, with a failure rate of less than 0.5%, reducing the losses caused by unexpected shutdowns. It is convenient for operation and maintenance, reducing labor costs.
With its long service life and modular design, the lane hot blast stove has become the preferred solution for upgrading the drying system of fertilizer enterprises.
Whether it is a new project or the renovation of an existing fertilizer manufacturing plant, Lane can provide the most optimized solutions to help customers achieve green production while reducing operating costs, and gain a competitive edge for enterprises in the context of dual carbon goals.
