Description

technical field

[0001] The invention belongs to the field of waste heat recovery and utilization equipment, and in particular relates to a slag waste heat recovery and utilization device. Background technique

[0002] A large amount of slag is produced in the production process of various industrial furnace equipment. These slags are often accompanied by a large amount of waste heat. According to calculations from technical data, this part of waste heat resources accounts for more than 17% of its fuel consumption. It can be seen that the utilization of slag waste heat is huge. potential. The utilization of waste heat from slag can not only reduce energy consumption per unit of product, but also reduce environmental pollution. Therefore, the utilization of waste heat from slag has considerable economic and social benefits. However, the existing devices for recycling slag waste heat have very low utilization efficiency, especially low heat value slag waste heat utilization ef...
