Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

The furnace will go to second stage (high fire) based on one of two conditions. 1) The time the furnace has been operating or 2) if the thermostat senses it needs to raise the temperature more than two degrees. For example, when a furnace rated at 80,000 BTU's first turns on it will operate at 60,000 BTU's (75% of 80,000).

High-Efficiency Furnaces: How Much Will They .

Furnaces that are a couple of decades old have an AFUE rating of around 60 percent – meaning that 60 percent of the fuel becomes heat, and 40 is lost. Many older models lose heat because of their pilot lights and the way exhaust gas is released up a chimney. Since the pilot light is always on, the furnace is burning energy without heating the ...

But new higher efficiency furnaces can have a lower Btu rating and still put out the same amount of heat. For example, a new 94 percent efficient furnace that is rated at 80,000 Btu puts out as much heat as an old 75 percent efficient 100,000 Btu furnace."
