In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.
often lead to build-ups in the kiln and calciner. For this reason, the ability to easily change flame shape and quickly return to the original burner settings when needed is key. A reliable and 'smart' burner The kiln burner is subject to extreme conditions. At the tip end, the flame temperature can reach around 2000˚C in a dusty and
that satisfactory burning conditions can be achieved. › • Increasing the Itb induces a shorter burning zone and, therefore, increases: - The temperature of the products of combustion in the vicinity of the burner; - Production of NOx in the kiln. • A reduction of the Itb produces a slower combustion rate, with a less energetic flame,
From our point of view, there are five key parameters when designing a burner. Secondary air entrainment, mixing secondary air and fuel, high turbulence, low NOx emissions and operational flexibility.Within such parameters, the D-FLAME means a …
The basic cement kiln system comprises a preheater in which feed material is prepared by heat exchange with hot exhaust gas, a fired rotary kiln in which the clinkering reactions occur, and a cooler in which the hot clinker exchanges heat with ambient combustion air. ...
