A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron, but also others such as lead or copper.
A gas furnace made in the early 1970s typically has an AFUE of about 65 percent. The lowest efficiency allowed by law for new gas furnaces is 78 percent, and some new models achieve 97 percent--near-total efficiency. The price of a furnace generally rises in step with its fuel efficiency.A furnace with a 90 percent AFUE might cost $1,000 more than a similar size unit with an 80 percent AFUE.eplacing the old furnace in your central heating system with a new, more efficient model can offset volatile energy prices. Money aside, today's furnaces pollute less and boost comfort by producing heat more steadily than older furnaces. Gas is the most common heating fuel and this report focuses on gas furnaces.
