Rotary kiln furnaces can be utilized for a wide range of procedures. The guideline fields of use of in a roundabout way warmed rotary tube furnaces are the warmth treatment of powdered, granular or smashed mass materials. The rotary kiln utilized has a power rating of 250kW and has been utilized for the gasification and pyrolysis of sewerage slime. This alongside different metal warmth medications can be researched with this apparatus. The kiln itself comprises of a pivoting metal tube, situated inside a stubborn lined ignition chamber. The warmed length of the heater is 1.8m long and 0.6m distance across. The kiln is furnished with three gas burners along the tube length, temperature controllers manage the gas stream to these burners, therefore controlling the burner task.. The burning air is provided and controlled by a diffusive air fan. The vent gases go around the rotary spend and of the burning load through a fireplace stack mounted on the highest point of the ignition load of the kiln. The pyrolysis chamber inside the turning tube warms the feedstock strongly, along these lines discharging the intricate hydrocarbons. The intricate hydrocarbons are then separated into littler fastened hydrocarbons. The pyrolysis procedure creates a hydrocarbon gas syngas gas, condensable hydrocarbons and a strong scorch. The rotary kiln encourages a characteristic pivot giving disturbance of the feedstock at high temperatures and taking into consideration a more entire transformation of all the feedstock to syngas. Item temperatures up to 1000°C are conceivable. As opposed to conventional gasifiers, it sits on a level plane and at a slight slant, taking into consideration a gravitational stream that moves the feedstock through the framework. The kiln can be slanted over the scope of 0-2.5degrees and at rotational accelerates to n rpm and consequently control the living arrangement time from passage to exit. The bed material inside the turning reactor tube is delicately beaten and prepared towards the release end by vanes inside the reactor's divider. The burn is released from the outlet of the kiln into the scorch/gas separator. The burn settles to the base of the strong separator and is gathered and evacuated through a fiery remains canister. The created syngas is drawn into a condenser at roughly 800°C where the condensable gases and any tar can be gathered. The rest of the non-condensable gases are then drawn out through the condenser at around 80°C into a warm oxidiser.

Rotary Kilns

Rotary kilns are used to uniformly heat lime, cement, carbon, fertilizer, stone and other aggregate materials. As the kiln turns the heated material is mixed, and new material becomes exposed to the flames and hot combustion gasses. Kilns are typically heated by a large flame introduced at the exit end of the process. The hot combustion gasses are then passed along the length of the kiln in a counter-flow direction. Many plants capture the hot gasses as they escape the entry end, and use this heat to pre-heat the product before it enters the kiln.

Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process.

Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size. The advantage for customers is lower investment and operating costs. These systems quickly gained excellent reputations among our customers.

Rotary dryers are almost always used for drawing moisture out of a material. Typically, they operate at temperatures between 800º – 1400ºF. Rotary kilns, however, are concerned with causing a chemical reaction. Therefore, they need to operate at much higher temperatures, between 1000º – 3000º.

Rotary kilns are designed to withstand much higher temperatures than a rotary dryer. Typically, if you are dealing with a direct fired rotary kiln, it is refractory lined with a brick or castable lining. This lining protects the steel shell. Rotary dryers are typically not lined, and their steel is not able to withstand such high temperatures. If you are dealing with an indirect rotary kiln, the kiln is not normally lined, so the shell of the drum has to be made out of a temperature resistant alloy instead of steel.
