Type of burner pipe in cement kiln

The aim is to develop a kiln burner with the capability to reach the maximum burner momentum at any flame shape, not only in one single point as with two primary air channel (or nozzle) burners. The burner momentum is the power available to the kiln operator to control the combustion process in the rotary kiln

    Apr 15, 2020 We are having a lot of coke build-up in the transport pipes to the burner both in the clinker kilns and in the lime kilns. In lime, the situation is more serious. We consider that it is due to the residue in toluene and we associate this with the amount of asphaltenes that the coke brings. What happens is that this is not measured regularly

    The kiln burner system is an important and integral component of a rotary kiln system to optimize the combustion of fuels to release heat in the kiln. Safety considerations, ease and flexibility of operation, product quality, energy efficiency, maintenance costs, and the environmental impact of the products of combustion are some of the most

    However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the

When inclining the axis of burner nozzle to that of the kiln it must be noted that a steep angle towards the material bed will permit radiation from the material to break out the fuel and increase the rate of combustion . it will also hinder the flow of uncommitted secondary air at combustion acroos the bed of material to extract heat & slow down the

    Burner pipes introduce fuel into the cement kiln where it ignites, creating heat for the process. Refractory castables line the outside of the burner pipe leading into the rotary kiln. These castables require proper refractoriness, good thermal shock resistance, alkali resistance, and strong abrasion resistance. Selecting the right high-temperature refractory helps create an improved burner design reducing failures

    Cement Kilns: Firing systems

    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 Bunsen burner, producing a flame that extends some way up the kiln
