Embodiment Construction

[0024] attached figure 1 A perspective view is schematically shown of a regenerator structure 10 consisting of large prefabricated refractory blocks (several of which are indicated by reference numeral 12) stacked on a base 14 to form side and end walls respectively 16, 18. It should be understood that the regenerator structure 10 is used in conjunction with the operation of a glass melting furnace (not shown). in the attached figure 1 The regenerator structure 10 shown generally in is of the type used in side-fired glass melting furnaces. However, the attributes of embodiments of the invention to be described herein are equally applicable to other glass melting furnace designs, such as end-fired glass melting furnaces.

[0025] The regenerator structure 10 includes a series of ports 10-1 for introducing preheated combustion air into a glass melting furnace (not shown) or exhausting combustion gases from the furnace, depending on the operating cycle. The top of the regen...

Abstract

Glass furnace regenerators having opposed pairs of side and end walls (16,18) formed of refractory blocks, a crown arch assembly (40) forming an arched roof of the regenerator, and a rider arch assembly (50) forming an interior floor of the regenerator are provided, wherein at least one of the crown arch assembly and rider arch assembly is formed of adjacently positioned one-piece monolithic precast structures of refractory materials.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims priority to U.S. Provisional Application No. 1500703.2, filed 16 January 2015, and U.S. Provisional Application No. 62 / 079,735, filed 14 November 2014, each incorporated by reference The entire content of said prior application is expressly incorporated herein. technical field [0003] Embodiments disclosed herein relate generally to monolithic refractory components for constructing regenerator structures associated with glass melting furnaces. In a particularly preferred embodiment, the unitary refractory crown and grate (cradle) rails form an integral part of the glass furnace regenerator structure. Background technique [0004] In the manufacturing process of making glass, raw materials including sand, lime, soda ash and other ingredients are fed into furnaces (sometimes called glass jars). The feedstock is subjected to temperatures above about 2800°F (about 1538°C) in th...
