Gas, Blast Furnace. It is a weakly combustible gas which passes out at the top of the blast furnace, such as used in recovery of iron from its ores. Compn of purified gas is given by Riegel (Ref), as follows H2 1.0, N2 59.6,... 

Related Calculations. Use the method given here when making combustion calculations for any type of gas used as a fuel—natural gas, blast-furnace gas, coke-oven gas, producer gas, water gas, sewer gas—from any source, domestic or foreign, in any type of furnace—boiler, heater, process, or waste-heat. When the air used for combustion contains moisture, as is usually true, this moisture is added to the combustion-formed moisture appearing in the products of combustion. Thus, for 80°F (300 K) air of 60 percent relative humidity, the moisture content is 0.013 lb per pound of dry air. This amount appears in the products of combustion for each pound of air used and is a commonly assumed standard in combustion calculations. 

Fig. 4.17. Blast furnace, a shaft furnace. The fusion zone has alternate layers, 1.5 to 3 ft (0.5-1 m) thick of coke, then fused slag and iron. If cleaned, the off-gas (blast furnace gas) can be used as a fuel. Courtesy of reference 11.

Pure carbon monoxide is extracted from synthesis gas, blast-furnace gas, or coke-oven gas by the following techniques (1) absorption of carbon monoxide by an ammoniacal cuprous salt solution at elevated pressure, followed by desorption by pressure release (2) low-temperature condensation and fractionation (3) liquid methane scrubbing and separation and (4) permeable membrane. 

Burners for Other Gases. Many industrial applications utilize coke-oven gas, blast-furnace gas, refinery gas, or other industrial by-product gases. With these gases, the heat release per unit volume of fuel gas may be very different from that of natural gas. Hence, gas elements must be designed to accommodate the particular characteristics of the gas to be burned. Other special problems may be introduced by the presence of impurities in industrial gases, such as sulfur in coke-oven gas and entrained dust in blast-furnace gas.
