Figure: Typical application of Gas/Oil Hot Air Stove in fertilizer production line
In modern fertilizer production processes, the gas/oil hot air stove serves as the core heat source equipment for drying and granulation operations. By burning natural gas or LPG, it generates clean hot air to provide stable and controllable thermal energy for fertilizer production.
The Gas/Oil Hot Air Stove primarily performs the following roles in fertilizer production lines:
· Drying heat source: Provides 100-300°C hot air for fertilizer particle drying
· Granulation support: Creates necessary temperature conditions for fluidized bed granulation
· Exhaust treatment: Enables hot air recycling with environmental protection equipment
Technical Highlight: Modern gas/oil hot air stoves achieve 85-92% thermal efficiency, saving 15-20% energy compared to coal-fired furnaces[1].
The Gas/Oil Hot Air Stove acts as the "thermal heart" of the fertilizer production line:
· Connects preceding batching processes with subsequent drying/cooling processes
· Determines drying efficiency and product quality stability
· Impacts the energy consumption metrics of the entire production line
· Enables precise temperature control with automated systems
Compared to traditional heat source equipment, gas/oil hot air stoves offer:
· Environmental benefits: Emissions meet EU CE standards
· Control precision: Temperature fluctuation within ±2°C
· Fast response: Only 15-20 minutes from startup to full load operation
With advancements in combustion control technology, new-generation gas/oil hot air stoves are evolving towards low-nitrogen combustion, intelligent regulation, and deep waste heat utilization, providing more efficient thermal solutions for green fertilizer production.
