Abstract: Gas-gas heaters (GGHs) are used to reheat gases through desulfurization in coal-fired power plants to reduce low-temperature corrosion and white smoke. Wrinkled heating elements are installed inside the GGH to perform effective heat exchange. An optimization study of the heating element shape was conducted to reduce the differential pressure effectively and improve performance. An integrated analysis model was applied. Based on actual operational data, a computational fluid dynamic analysis was conducted on the L-type heating element and GGH system. The experiments applied the optimal latin hypercube sampling method, and numerical analysis was performed for each sample. Based on the response surface, the result of the sample was optimized through the pointer algorithm. For the integrated analysis model, validation was performed by comparison with the actual operational data, and the thermal-fluid characteristics of the heating element and GGH system were analyzed to set three parameters: plate angle, undulated angle, and pitch 1. From the optimization result, increases in the undulated angle and pitch 1 reduce the pressure drop by widening the heating element cross section. By increasing the plate angle, the heat transfer area is secured and the reduced heat transfer coefficient is compensated, improving the GGH performance.

TL;DR: In this article, an investigation was conducted into a failure of convection section tubes in a process gas heater in a steel-making company, which was attributed to metal dusting.
Abstract: An investigation was conducted into a failure of convection section tubes in a process gas heater in a steel-making company. Thorough study using various characterisation techniques showed that the failure of the tubes, which were made of low-alloyed steel ASTM A335 P22, was attributed to metal dusting. The attack was accelerated because of the use of incompatible tube material for the intended operating conditions. Moreover, thermal fatigue cracks were discovered on the tube surfaces. Such cracks might have been caused by the high number of plant start-ups and shutdowns. Failure contributing factors and recommendations to avoid similar failure are discussed in this article.

The utility model provides a three -dimensional heating system who reduces internal stress that prints carries out temperature control to three -dimensional printing apparatus is inside, and the heat treatment of materials manufacturability of applying in a flexible way is easily realized eliminating the shaping metal material's of intracavity internal stress to improve the shaping quality that 3D printed the component that takes shape.
