Problems solved by technology
[0003] The flame non-reversing regenerative combustion technology is developed on the basis of the traditional regenerative combustion technology. However, this technology only recovers the waste heat of the exhaust gas and does not better organize the combustion, resulting in insufficient fuel combustion and partial fuel resources. Waste, so the system does not achieve the best energy-saving effect

The invention discloses a high-temperature air combustion device. The device comprises a combustion chamber, a burner extending into the combustion chamber, a first composite heat exchanger, a second composite heat exchanger, a four-way reversing valve, an air blower and an induced draft fan, wherein the four-way reversing valve is connectedbetween the first composite heat exchanger and the second composite heat exchanger, the air blower is connected with the four-way reversing valve, and the first composite heat exchanger and the second composite heat exchanger are connected with the combustion chamber through a first connecting air port and a second connecting air port respectively. Through the first and second composite heat exchangers, when a system works stably, the temperature of a regenerator high temperature area is kept high, combustion-supporting air in a primary combustion-supporting air pipeline can be heated to 300-500 DEG C, and the hot air is directly supplied to the burner to be mixed with fuel, so that high-temperature combustion of the fuel is realized.
Description
technical field [0001] The invention belongs to the technical field of kiln combustion, and relates to a high-temperature air combustion device. Background technique [0002] In my country's non-ferrous metal industry, in order to reduce fuel consumption in the production process of melting furnaces, materials have been melted by fuel heating in recent years. As energy prices continue to rise, fuel consumption costs account for an increasing proportion of processing costs, accompanied by a large consumption of natural resources and a large amount of carbon emissions. Relevant research institutions and production companies are constantly exploring new technologies to reduce costs, fuel consumption and carbon emissions from combustion. Among them, the flame non-reversing regenerative combustion technology has gradually been applied in the melting furnace industry. [0003] Flame non-reversing regenerative combustion technology is developed on the basis of traditional regener...
