摘要： In a counterflow non-contact heat exchanger, tube bundles carry fluid back and forth across a hot gas path. As the fluid in the tubes flows vertically downward the temperature of the fluid rises. As the gas rises in the heat exchanger it loses heat due to the heat exchange process. This means that the temperature profile of a tube bundle will show a greater thermal expansion in the lower tubes. The present invention seeks to provide an efficient and improved support arrangement for heat exchanger tubes to accommodate this phenomenon by supplying a pivotally mounted tube support plate which will rotate and translate slightly from a substantially vertical plane to accommodate thermal expansion. Further, if there are multiple tube bundles, additional tube support plate sections will allow a tube support plate to articulate in sections to accommodate thermal movement.

摘要： In a hot gas duct wherein it is desirable to retain heat within the duct by insulated sidewalls and wherein the duct is substantially longer than it is wide, it is necessary to support the duct against excessive deformation in the lateral direction. Exterior support structures are unacceptable because locating cross members or struts becomes problematic. Interior support structures must be carefully designed so as not to inhibit thermal expansion and contraction within the duct. It is proposed that a lateral bracing system or truss be disposed entirely inside the hot gas path and provision be made to ensure adequate facility for uniform expansion of the truss within the hot gas duct.
