Tar formation is the main bottleneck for biomass gasification technology. A novel rotary kiln type biomass gasification process was proposed. The concept design was based on air staging and process separation. This concept was demonstrated on a pilot scale rotary kiln reactor under ambient pressure and autothermic conditions. The pilot scale gasifier was divided into three different reaction re...

Rotary kiln incineration technology has the advantages of strong material adaptability and a simple treatment process been widely used in hazardous waste treatment. However, actual caused problems such as ring formation system due to lack research on slagging mechanisms. In this paper, phenomena occurring second half rotary kiln, exit flue secondary combustion chamber, wall quench tower are ana...

This paper presents two novel methods for segmenting the solid bed in infrared image sequences of metalrecycling rotary kilns. Exploiting the different dynamics and temperatures of gas phase, solid bed and kiln wall, we developed filter chains for an image segmentation of the solid bed. For the image acquisition we employed infrared cameras with a spectral filter. Two image processing algorithm...

Maintenance experts involved in managing major maintenance activities such as; Major overhauls, outages, shutdowns and turnarounds (MoOSTs) are constantly faced with uncertainties during the planning and/or execution phases, which often stretches beyond organisation’s standard operating procedures require intervention of staff expertise. This underpins a need to complement sustain existing effo...

In this work, the performance of a cement plant with integrated calcium-looping (CaL) system being developed in H2020 CLEANKER project are simulated and benchmarked against alternative CO2 capture options, namely: (i) Tail-end CaL configuration (an end-of-pipe option, circulating fluidized bed reactors) (ii) Full Oxyfuel (where both pre-calciner rotary kiln operated oxy-combustion mode), (iii) ...

The purpose from testing studies to discovery out the efficiency of CKD Al-Muthana city Iraq government removal Methylene Blue Dye (MB) in simulated textile wastewater generated Al-Diwaniyah factory government. discharge industries that contain methylene blue dye is removed by adsorption through cement kiln dust, therefore, was studied this case. best electrostatic action basic between and dust...
