Abstract

Abstract Separate intake air and exhaust gas manifolds along each long checker-brick regenerator, each of which manifolds have separate adjustable sideports, valves, or gates in each branch duct that do not have to be readjusted each regeneration cycle, and which gates may be preadjusted and/or at-will adjusted from a common and even remote location.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 114 words
A regenerator system for a furnace having a pair of elongated regenerators through which intake air and exhaust gases alternately pass, and each said generator having a longitudinal duct along its top connected to a plurality of side ports said system comprising: (A) an input manifold for said intake air to each regenerator, said manifold having branch ducts spaced along and connected to its said regenerators, (B) an output manifold for exhaust gases from each regenerator, said manifold having branch ducts spaced along and connected to its said regenerator, (C) separately operative gates in each of said branch ducts, and (D) separate reversing valve means between said input manifolds and between said output manifolds.
Claim 2
Dependent Claim 114 words
A regenerator system for a furnace having a pair of elongated regenerators through which intake air and exhaust gases alternately pass, and each said generator having a longitudinal duct along its top connected to a plurality of side ports said system comprising: (A) an input manifold for said intake air to each regenerator, said manifold having branch ducts spaced along and connected to its said regenerators, (B) an output manifold for exhaust gases from each regenerator, said manifold having branch ducts spaced along and connected to its said regenerator, (C) separately operative gates in each of said branch ducts, and (D) separate reversing valve means between said input manifolds and between said output manifolds.
Claim 3
Dependent Claim 26 words
A regenerator system according to claim 1 wherein said manifold ducts are tapered from one end to the other along the connections to their branch ducts.
Claim 4
Dependent Claim 34 words
