When fired with solid fuels like coal, the HGG is strictly executed in vertical design to enable ash removal. When fired with gaseous or liquid fuels only, a horizontal design is commonly used. The flame is generated by a standard monoblock burner when standard fuels are in use, or by a tailor made Unitherm burner for coal or special gases.

The shaft refers to a vertical vessel where the calcining takes place. Because of the weight of the bed of material in the shaft, there are limits on the size and strength of the type of limestone that can be calcined. Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating.

Vertical Shaft Brick Kilns - leslodges-marseille.fr. How to build a small vertical shaft lime kiln Practical Action 2 people work. The fuel used at Chegutu is coal, but it is also possible to use charcoal and other solid fuels. In general, shaft kilns use less fuel than batch kilns because less heat is wasted.
The burners are divided into single duct burners and multiple duct burners. Single-channel burner is the rotary kiln early coal-fired burner, single duct that only one coal duct, a high air volume, not suitable for burning low-quality coal and anthracite. A multi-burner burner is a combustor with a gas delivery duct greater than or equal to three.
The kiln owner abandoned the concept and used conventional burners. The first kiln, my studio kiln, built in 1975, uses 50 tubes (two inches in diameter) in the chimney and is still in regular use. The heat exchanger tubes were originally extruded as mullite muffle kiln flame tubes for kilns built by Denver Fire Clay Company.
