  • Rotary kiln,Lime rotary kiln,Clinker rotary kiln,Indirect

    A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object. It is made up of a strong reinforced steel outer shell that is coated with a heat-resistant inner lining, support rollers and a drive gear to keep the contents in a continuous rotating motion and internal heat exchangers capable of producing temperatures well over 2732

    Other typical indirect fired rotary kiln applications include chemical laden soils, absorbents, tank wastes, and other inert substrates. As these examples indicate, there are countless applications wherein an indirect fired rotary kiln may result in a more cost effective system overall.

  • Cement Plants Kidde Fire Systems

    The Cement/Lime industry has had to search for a way to reduce costs and this has resulted in the near standardization of coal-fired (or coke) systems for firing up the kiln. These systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network.

  • ALTERNATIVE CONTROL TECHNIQUES DOCUMENT— NOx

    In cement manufacturing, conditions favorable for formation of nitrogen oxides (NO x ) are reached routinely because of high process temperatures. Essentially all NO x emissions associated with cement manufacturing are generated in cement kilns. In cement kilns, NO x emissions are formed during fuel combustion by two primary mechanisms:

  • Nox Control Technologies for the Cement Industry Final Report

    For effective staging of combustion air to reduce NOX emissions, cement plants must have indirect-fired kilns. In a direct-fired cement kiln, air used for conveying pulverized coal from a coal mill, i.e., primary air, is typically 17 to 20 percent of the total combustion air.

    "Firing" in cement industry parlance is the supply of heat to a kiln by use of a burning fuel. Throughout the early history of the industry, fuel was added to static kilns in lump form, pretty much in its "as-received" state. With the advent of the rotary kiln, it was necessary to develop sophisticated means of preparing the fuel and injecting it into the kiln system.
