Thermal Stresses in Coal Conversion Pressure Vessels Built of Layered Construction

  • Theodore R. Tauchert


Radially varying temperature and thermal stress distributions in layered pressure vessels designed for use in coal conversion processes are investigated. A least-squares residual method which incorporates Lagrange multipliers for satisfaction of initial, boundary and interface conditions is employed in the case of transient heat conduction. Assuming orthotropic elastic behavior, a general solution is formulated for the stresses induced by combined temperature, pressures and initial interferences between layers. The effects of heat-transfer resistance at layer contact surfaces are illustrated through several numerical examples. Representation of a layered vessel as a homogeneous cylinder having an effective thermal conductivity, for the purpose of predicting thermoelastic response, is also explored.
