Gasification is a process wherein carbonaceous materials are dissociated at high temperatures in an oxygenstarved thermal reactor to form a fuel gas that is mainly composed of carbon dioxide, carbon monoxide, hydrogen, methane, and water vapor.

Nelson Machinery supplies Direct Fired Rotary Kilns worldwide manufactured by FL, Feeco, Fuller, Traylor, KVS, and more. A Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. The basic components of a rotary kiln are the shell, the refractory lining,...

High energy syngas production by waste tyres steam gasification in a rotary kiln pilot plant. Experimental and numerical investigations

Direct Fired Rotary Calciners A directly heated rotary dryer from Thermal Processing Solutions can be gas or oil fired, or hot air utilizing a heat exchanger or heating elements fired in a parallel flow or counter flow arrangement Utilization of a heat exchanger allows the use of .

The rotary kiln reactor is a pilot scale having a nominal feeding mass rate of 20 kg/h; the size of this plant is particularly meaningful for the further development at industrial scale; autothermal digestate air gasification was targeted in the rotary kiln plant, to avoid external energy supply and to recover syngas suitable for heat and power; a theoretical simulation study was carried out to identify plant engineering .

HarbisonWalker International offers THERMAX ® and Rib Back brick. Both have hollowedout cold faces that help provide insulation, thereby giving our customers cooler shell temperatures. Tumblers are precast or cast in place and are installed in lime rotary kilns to "agitate" the load. This provides improved heat transfer and lime quality.

Indirect Fired Kilns. Horizontal indirect fired kilns have proven to be the 'workhorse' of carbon regeneration for decades. The concept of the equipment is based on a rotating tube within a hot combustion chamber. This tube is fed with fouled carbon from a feed screw. Since the tube has angled lifters, its rotary motion imparts a gentle momentum to the carbon.

Indirect Fired Rotary Kilns are our core technology. We design and manufacture our kilns to meet the requirements of carbon regeneration, gasification and pyrolysis applications. Originally designed for carbon regeneration applications these kilns are perfect .

rotary kiln operations. Regardless of rotary kiln size or configuration the basic principles outlined in this manual govern the reliable operation of every rotary kiln, calciner, dryer, incinerator, digester and cooler application.

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.

The solid residues of a waste pyrolysis process often contain a lot of chemical bound energy. This energy could be used by a so called "Carbon Recovery Unit" (CRU). The gasification takes place in a rotary kiln. The ratio of the feeded air and steam has to be balanced to heat up the char to approximately 900°C.
