Problems solved by technology

[0002] At present, most of the calcination methods in existing industrial shaft kilns are heated by burning coal or by installing burners around the shaft kiln and heating by gas combustion. Both of these two types of industrial shaft kilns have certain limitations in practical applications. Defects and disadvantages, among them, during the calcination process of coal-fired industrial shaft kilns, coal and massive industrial raw materials are mixed together, and the burning coal is very likely to pollute the calcined products and reduce the quality of the calcined products; In the process of calcining massive industrial raw materials in the industrial shaft kiln with gas burners around the burners, due to the limitation of the length of the flame of the burner, when the internal size of the kiln body is large, the flame generated by the burning gas cannot reach the center of the shaft kiln, thus The calcined products in the center of the kiln body cannot be burned through, or the calcined products around the kiln are over-burned, resulting in the occurrence of situations that reduce the quality of the calcined products, and even severely over-burned unqualified products

Abstract

An industrial vertical kiln with central burning device in fuel-gas heating mode consists of kiln body, material supplying unit, fuel conveying unit, material output unit, smoke exhausting unit, burning unit and control unit. It is featured as preheating fuel gas and combustion-supporting air by heat exchanger, making casthouse pressure of mixed fuel gas and combustion supporting air be about 10Kpa with temperature being greater than 150deg.c under action of combustion-supporting air fan and then burning preheated- mixed fuel gas and combustion-supporting air in integrated burners.
