Abstract
Description
(1) Technical field
[0001] The invention relates to a furnace waste heat recovery device, in particular to a waste heat recovery device for industrial furnace high-temperature flue gas. (2) Background technology
[0002] Industrial furnace is the key equipment for industrial heating, widely used in many national economic industries such as machinery and metallurgy. There are many types of industrial furnaces, and at the same time they are high-energy-consuming equipment. The problem that the business seeks to solve. At present, the recycling of flue gas from industrial furnaces can be divided into the following three methods:
[0003] 1. Direct use method, for products that do not have strict requirements on the drying medium, the flue gas can be directly drawn into the working room of the drying product by a fan, and the product can be dried directly;
[0004] 2. Indirect use method, the flue gas extracted from the flue is directly sent into the pit or metal pipe, and the...
