摘要:
A heat transfer element assembly for a rotary regenerative air preheater for spacing the heat transfer plates to optimize performance and reduce costs. Rectangular or trapezoidal spacer tabs are punched and bend outwardly from the plates and arranged in parallel rows. The tabs have specific height and length ranges and ratios and the area of the tabs to the area of the remaining portion of the plate has a specific ratio range.
摘要:
A supercritical carbon dioxide power generation Brayton cycle system and method that employs an alternate heat recuperation method and apparatus that utilizes switched banks of bead filled tanks to accumulate and recover the thermal energy of the two streams of working fluid in such a way that the variable thermal properties of the supercritical carbon dioxide can be accommodated without significant loss of thermal efficiency.
摘要:
A radiator device includes a plurality of filler plates made from a low heat conductivity and high specific heat such as for example gadolinium/rhodium and a plurality of spacer members disposed on each one side of the filler plates to form a fluid flow passage and a housing member accomodating the spacer and the filler plates.
摘要:
The disclosed ceramic heat exchanger has a stress relief layer disposed in the proximity of joint between a hollow hub and a honeycomb structural body integrally joined to the outer circumference of the hub, the stress relief layer having the difference in thermal expansion of not greater than 0.1% at 800.degree. C. relative to the hub.
摘要:
The thermal shock resistance of a honeycombed structure or a structure having a honeycombed surface formed by bonding together a plurality of cellular segments each having a honeycombed face forming a portion of the structure or surface of the structure, respectively, is improved by recessing the bond joints between the joined cellular segments from the surface. The thermal shock resistance of a heat recovery wheel operated in a counterflow heat exchanger system and formed from joined cellular segments is improved by recessing the bond joints joining the cellular segments, preferably approximately one-half inch (12.7 mm), from the face of the wheel exposed to the gases at their highest temperatures.
