furnace frame

Furnace frame, also known as coking furnace chamber, is a device used to store coking coal during the coking process. The furnace frame is one of the main components of the coking furnace, and its structural design and material selection directly affect the service life, production efficiency, and safety of the coking furnace. The following provides a detailed introduction to the furnace frame.

I. Structure of the Furnace Frame

Top: The top of the furnace frame usually has a feed inlet for loading raw coking coal into the furnace chamber.

Side walls: The side walls of the furnace frame are responsible for supporting and fixing the furnace chamber structure, typically made of refractory bricks or refractory castables.

Bottom: The bottom of the furnace frame is usually a slag collecting trough used to collect the slag produced inside the coking furnace.

Gas outlet: The gas produced during the coking process is discharged from the bottom of the furnace chamber and enters the coke gas purification device after gas cooling and purification.

II. Materials of the Furnace Frame

Refractory bricks: Refractory bricks are commonly used as the lining material for the furnace frame, with the characteristics of high temperature resistance and erosion resistance, effectively protecting the furnace chamber structure and extending its service life.

Refractory castables: Refractory castables are used to fill the side walls and the bottom of the furnace frame, mainly made of alumina and silica refractory materials, with good resistance to erosion.

Steel: The outer shell structure of the furnace frame is usually made of steel to provide the necessary strength and rigidity, ensuring the stability and safety of the furnace frame.

III. Functions of the Furnace Frame

Coal loading: The furnace frame serves as a storage device for coking coal, ensuring the continuity and stability of coking production.

Protection of the furnace chamber structure: The refractory lining of the furnace frame effectively protects the furnace chamber structure, extending the service life of the furnace chamber.

Slag collection: The slag collecting trough at the bottom of the furnace frame collects the slag produced inside the coking furnace, maintaining the cleanliness of the furnace chamber.

Gas emission: The gas outlet at the bottom of the furnace frame smoothly discharges the gas produced during the coking process, providing conditions for the subsequent gas treatment.

IV. Maintenance of the Furnace Frame

Regular cleaning: Regular cleaning of the furnace frame to remove ash, slag, and other impurities, maintaining the cleanliness of the interior of the furnace frame.

Routine inspection: Regular inspection of the furnace frame to promptly repair or replace any cracks, wear, corrosion, and other issues found.

Temperature control: Control the operating temperature of the furnace frame to prevent material damage from excessive temperatures.

In summary, the furnace frame is an important component of the coking furnace, playing a significant role in ensuring the safety, stability, and high efficiency of coking production. Proper material selection, scientific structural design, and strengthened maintenance and management can effectively extend the service life of the furnace frame, improve production efficiency, reduce energy consumption, and provide guarantee for the sustainable development of coking enterprises.
