silica checkers for blast furnace stoves
Use of blast furnaces CustomWritings
· In 1870 Whitwell Stoves designed and produced larger stoves with heating surfaces of about 8546 m2 which could deliver °C hot blast to the furnace. These were also the first stoves to use hexagonal refractory checkers cast iron checker supports and semi-elliptical combustion chambers to enhance the distribution of gas throughout the checkers.
Application of oxygen enrichment in hot stoves and its
· Oxygen enrichment Hot stoves Blast furnace Energy system . 1. Introduction . In the process of iron-making hot stoves (HS) are used to preheat air used in the blast furnace (BF). The preheated air is called hot blast. A higher blast temperature will lead to lower coke consumption in BF operation hence the energy consumption and CO. 2
