What is a reverberation furnace?

Reverbered furnace is a type of melting furnace or metal-refining furnace that has been used since the middle of the age of 17 and is commonly known as an open-out furnace. It melts the ore containing the metal by generating hot gases near the roof of the furnace without ever coming into direct contact with the source of fuel used to warm it up. Because the reverberation furnace is a centuries -old construction and has a limited temperature range, it is usually used to melt non -ferrous, softer metals than iron, such as copper, aluminum and tin. The furnace design was also used to introduce nickel and more metals environmentally risk, such as lead, which gave it a negative reputation for the amount of air pollution it can generate.

industrial furnaces may have complex or simple patterns based on the exact amount of temperature control it must have, and the types of types that they are processing. The reverberation furnace is a relatively simple model that usually has rectangularíkovou uzavřenou komoru s depresí ve spodním středu známém jako krbu. Heated flames or hot gases are directed through the fireplace from above and flowed from the furnace directed by one or more smoke sides along the other side. When hot gases and flames are inserted into the furnace chamber, the opposite wall acts as a partition from which it bounces to continue circulation in the chamber. One of the primary needs of the structure for the reverberation furnace is that the path for burning fuel is as soon as possible and as useful as possible, because it allows more intensive heating of the interior and rapid melting of ore.

While the metallurgical furnace can rely on any of the three types of heat transfer to make ore, from lines to convection and radiation, usually lead or heat transfer from one solid surface to another is the most effective. Naproti tomu dozvuková pec se téměř výhradně spoléhá na konvekci a záření, kde se teplo přenáší do rudy okolním vzduchem. To znamená, že dozvuková pec bere mnohem více paliva k zahříRudy and the ore than refractory, which relies on the surrounding heat, which retains in Fireclay brick to feel metal. Softer metals, such as bronze or compounds as glass, are usually processed in a reverberation oven because they have lower melting points, although some reverberation designs were also used to process steel in special cases.

Although the improvement of the reverberation furnace, such as the production of a roof from the refractory brick to increase the heat level, has made them the more versatile class furnace class, retained a large part of their centuries -old design. The name of the reverberation comes from the shape of archiving into the center of the roof, which allows hot gases to flow up and then bounce back into the furniture of the centers. The location of smoke or flue gas ducts from exhaust gases is generally at the lowest point of the roof and the highest point of the roof arch is immediately above the place where fire and hot gases are tied.

reverberatory furnace is a general form of a puddling furnace that uses the same princePicoming with hot gases to cut iron ore. However, the primary use for reverberation furnaces since 2011 is to feel soft lead metal to clean lead. These furnaces have several potential weaknesses where the surrounding environment can be contaminated by lead. These include a furnace under positive pressure, emissions caused by dust and leaks, because the furnace is not a completely sealed chamber, and the release of leadership into the environment when the ore is transferred to the furnace and the pour of pure metal is removed.
