Guidelines for shaping and designing of steel liners in industrial chimneys

<ns3:p>The article presents issues related to the shaping and design of steel liners in industrial chimneys, steel, ceramic and reinforced concrete. The design of steel liners is governed by the principles and requirements specified in Eurocodes PN-EN 1993-3-2 and prEN 1993-3, as well as related standards: PN-EN 1993-1-6; PN-EN 13084-1; PN-EN 13084-6 and PN-EN 13084-7. The principles of design and adopted material solutions for steel liners are described. The principles of designing these liners taking into account the effect of temperature difference and the effect of deformation or displacement of the chimney shaft are also presented. In conclusion, the article recommends the realization of steel double skin chimneys with a stainless steel liner as a solution that meets the standard requirement for the durability of steel chimneys</ns3:p>
