In a direct-fired rotary kiln, the burner is situated inside the kiln body, that is, inside the reaction chamber. The material is heated directly by the burner flame and the stream of hot gas produced by the burner. These kilns are usually lined with refractory (heat-resistant) material so that they can be operated at higher temperatures than ...

A large number of kilns now use alternative fuels. Many of them substitute these alternative fuels through the main kiln burner as well as in the pre-heater / pre-calciner; the chemical and heat-release changes caused by inevitable short-term fluctuations in the fuel(s) mix has a major influence on the thermal, coating and atmosphere conditions existing through the rotary kiln into the pre ...

Apr 16, 2021The function of the cement kiln burner is to send the pulverized coal and the air required for combustion into the furnace, combined with a reasonable air flow structure, so that the fuel can quickly ignite and burn stably. Coal air is rapidly and fully mixed with primary and secondary air, which can quickly heat up, catch fire and burn out.
