Problems solved by technology

The labor used on site adds to the cost of the air preheater as it is more expensive than shop labor
Also, labor used on site assembles parts with less precision than shop labor due to lack of shop fixtures
Therefore, there is a risk of installation-related errors requiring later rework

Embodiment Construction

[0027] 1 is a perspective view, partially broken away, of a conventional air preheater 10 showing a housing 12 in which a rotor 14 is mounted on a drive shaft or column 16 for rotation in the direction indicated by arrow 18 . The wheel includes a plurality of sectors 20 each containing a plurality of blue frame modules 22 and each sector is defined by a partition 24 . The blue frame module 22 includes heat exchange surfaces. The housing 12 is divided into a flue gas side and an air side by means of a flow-tight sector plate 26 . The corresponding sector plate is also located at the bottom of the unit. The hot flue gas enters the air heater through the gas inlet duct 28 , flows through the rotor 14 where heat is transferred to the blue frame module 22 and then exits through the gas outlet duct 30 . Simultaneously flowing air enters through the air inlet duct 32 , flows through the blue frame module 22 where it gains heat and then exits through the air outlet duct 34 . The ga...

Abstract

A semi-modular rotor module (60) for an air preheater (10) having a circular rotor includes a lug assembly (62) having a lug front (80), a lug back (86) spaced radially outward from the lug front (80). A single main diaphragm (64) extends radially from an inner end portion to an outer end portion, with the inner end portion being mounted to the lug front (80) on a first side of the lug assembly (62). The outer end portion is mounted to a rotor shell (66) whish is spaced radially from the lug back (86). At least one intermediate diaphragm (78) extends radially from an inner end portion, mounted to the lug back (86) at a position intermediate the first and second sides of the lug assembly (62), to an outer end portion mounted to the rotor shell (66).

Description

technical field [0001] The present invention relates to a rotary regenerative heat exchanger commonly used as an air preheater, and more particularly to a rotary regenerative heat exchanger with a semi-modular rotor configuration. Background technique [0002] Rotary regenerative heat exchangers are used to transfer heat from one hot gas stream, such as hot flue gas stream, to another cold gas stream, such as combustion air. The runner contains a mass of heat-absorbing material which first rotates through a channel for the hot gas flow, where heat is absorbed by the heat-absorbing material. As the rotor continues to rotate, the heated endothermic material enters the channel for the cold air flow where heat is transferred from the endothermic material to the cold air flow. [0003] In a conventional rotary heat exchanger, a cylindrical runner is arranged on a vertical central runner post and is divided into sector-shaped compartments by a number of radial partitions, called ...
