Hot blast – Wikipedia

2019-6-8 · Hot blast also allowed higher furnace temperatures, which increased the capacity of furnaces. As first developed, it worked by alternately storing heat from the furnace flue gas in a firebrick-lined vessel with multiple chambers, then blowing combustion air through the hot chamber. This is known as regenerative heating.

Top Combustion Hot Blast Stove – ECCJ

2018-12-5 · A hot-blast stove is a facility to supply hot air to a blast furnace continuously. In the combustion (heat accumula – tion) phase, heat energy in hot exhaust gas from a burner is accumulated in checker bricks and, in the ventila-tion phase, a large quantity of air is blown through the checker bricks to raise the temperature of the air.

Blast furnace – Simple English Wikipedia, the free

2019-5-28 · The blast furnace is the biggest chemical reactor. Blast furnaces are also called high ovens. A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside the case. The hot furnace cannot melt these bricks. The furnace is cooled with water running inside part of the case and bricks.
