The volatilization of silica (SiO2) from refractory concrete has been studied extensively and reaction thermodynamics are also well published. Understanding the degradation of the refractory containing silica in hydrogen /steam gases at temperature is important when designing and selecting refractory linings for gasifiers...

The heat transfer analysis of multi-layer refractory concretes in both transient and steady state conditions is particularly important for many pyro-processing industries. Knowing the temperature profile through the different layers is important for design and operational trouble-shooting. It is clear that the design...

The design of static refractory structures has traditionally been based on empirical or trial and error methods and has evolved over the years. Design methodology has been based on heat transfer analysis for material selection and the most common selection criteria are the published scaling temperatures of the anchor steel...

Part 1 of this paper has highlighted the errors in refractory design methodology and a general methodology for the design of monolithic refractory structures is presented. In particular it has been shown that traditional concepts or guidelines are erroneous which are not based on engineering science can leave open the...

Understanding the behaviour of monolithic refractory concrete is critically important for engineers when designing refractory linings for high temperature environments. As cement plants, power plants and other industries push for longer runtimes to reduce maintenance costs, the performance of refractory linings...

The reliability of stainless steel refractory anchors in refractory lined process vessels is becoming more critical as companies chase greater efficiencies and safety. Therefore understanding the failure mechanism of stainless steel refractory anchors is the key to improved production efficiencies and better safety...

Summary: The P-Response® system is a fast screening method for identifying suspect areas of civil and refractory concrete, non-destructively, as opposed to visual inspection or core drilling. The impact-echo technique (P-Impact) can be used to verify suspect areas. The P-Response® technique has been adapted to...

Concrete materials like refractories are strong in compression and very weak in tension. This generally means that their fracture toughness is low. Stainless steel fibres are commonly used in an endeavour to improve refractory fracture toughness...

Rotary kilns are one of the most widely used pieces of processing equipment. They are used for drying or calcining a variety of products including sand, aggregates, limestone and food products. With an ever increasing focus on reducing greenhouse gas emissions, the continued or increased use of rotating kilns can only be achieved by...

The drying of products like sand, aggregates, fertilizers and food products is an important step in industrial processes. With an increasing focus on reducing greenhouse gas emissions and energy demand the design of drying units has become critical. In the past rotary dryers have been in some cases thermally very inefficient...

Refractories are integral parts of any pyroprocessing plant. Consequently, any failure will cause many hours of lost production. To make matters worse the duration of the production loss is exacerbated by long, cool down periods, before repairs can be carried out, and by slow heat-up rates which are necessary to...
