That said, there are challenges. It burns quickly and with a very different thermal profile to conventional fuels. But with challenges come KHD solutions. We have adapted the Pyrojet® nozzle design to allow a fuel mix of up to hydrogen, while maintaining a similar heat transfer in the rotary kiln as fossil fuels.

The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (80-90%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.
a sufficient amount of kiln dust acting as a catalyst. The abatement-inhibiting influence of water can only be reduced slightly as the water content in the rotary kiln exhaust gases is primarily dependent on the type and composition of the kiln fuel. To achieve best possible reduction premises, Pyroredox makes use of the Boudoard reaction.

Because of its obvious advantages, it quickly became the industry standard, and remains the go-to pairing for cement production in a rotary kiln today. Not long after, KHD were responsible for introducing precalciner technology using highly-efficient flash tube-type calciners, after Japanese inventors developed the so-called RSP pot-type calciners.
One of the things you want to avoid is fall-through of coarse material to the kiln. The Pyroclon ® R features a specially-designed restricted connection (or orifice) between the kiln inlet chamber and the riser duct that prevents large particles, such as coarse alternative fuels, from entering the kiln inlet chamber.. This restricted orifice also helps maintain the gas balance, not only in ...

The second essential step is to extend fuel residency time – by about four seconds – in the CO-rich atmosphere of the Pyroredox ®.This allows the CO to react with the NO X in the kiln exhaust gases and reduce them to CO 2 and harmless N 2 nitrogen.. After the kiln exhaust gases have been reduced, the remaining lean gas is fed into the calciner, where oxygen-rich tertiary air …

The thermal efficiency of rotary kiln clinker coolers of all types of design is within the range of 40 to more than 80%. b)Another criterion for judging the cooler efficiency is the temperature difference between the hot clinker entering the cooler and the hot secondary air leaving the Furthermore, the best cooler is the particular cooler which, because of its general efficiency, supplies the ...
The cement pyroprocess is exceptionally hot – upwards of 1,500 °C, in fact. To generate this heat, several burners are used at various points in the process. But multiple burners add complexity to the system that is not easily managed manually. Our smart Burner Management System (BMS) is the solution: able to control all firing systems, whoever the supplier and whatever the fuel, the …
