Burner Pipe Rotary Kilns

On some rotary kilns, the primary air pipe is fixed slightly below the center of the kiln, in an effort to offset the flame buoyancy. Most kilns, however, have facilities for adjusting the position of the primary air pipe and the burners, thus the operator can change flame direction and, to a limited degree, change the shape of the flame.

Burner integrated into a combustion chamber. Product Cooling Requirements. Though not part of the rotary kiln system itself, rotary kilns are often accompanied by a rotary cooler for product cooling requirements.. Rotary coolers can be …

In some applications, this can be by a continuous pilot burner, but in rotary kilns this is best achieved by ensuring recirculation of hot gases as the ignition source for new fuel. Once a kiln is up to operat-ing temperature, radiation from refractory provides the ignition energy. ... Calciner burner designs can vary from a simple pipe through ...

A burner for a rotary kiln consists of a central pipe (5) for introducing an oil or gas lance, a first concentric pipe (8) for introducing primary air and a second concentric pipe (1) for introducing a mixture of solid fuel and carrier air into the burning zone of the kiln. The pipes (5, 8 and 1) form mutually annular channels, the primary air channel being located inside the solid fuel/air ...

In rotary kilns, irrespective of the fuel used, the most obvious common feature of the firing system is the firing pipe (burner pipe) which passes through the kiln hood at the kiln's hot end, arranged more or less along the kiln's centre line, and through which the fuel is projected into the kiln at high velocity. The effect is rather like a ...

Lime recovery kilns can be as long as 380 feet and as wide as 15 feet in diameter. These vessels are refractory lined and typically zoned into five major sections including the chain section, tumbler section, intermediate zone, burning zone, and refractory dam. The operating environment in each section varies and dictates refractory selection.

The direct-fired rotary kiln's character is that the combusted materials are directly in contact with the raw material being processed. In traditional rotary kilns, pulverized coal is generally fed into the kiln and ignited by a burner, so that the mixed coal materials are burned and heated to the required temperature.

Straight burner pipes are designed for normal "full-speed" produc­tion operation and usually do not deliver satisfactory flame shapes and characteristics during start-up and kiln slow-down periods.

Rotary Kilns. Modern rotary kilns can be safely lined with just two types of bricks: 1) high alumina in the calcin-ing and discharge zones, and 2) magnesia-spinel in the lower transition, upper transition, and burning zones. Many new kilns have been successfully commissioned with this simplified lining configuration, with good results.
