Technical solution—Cooling furnace exhaust gas waste heat recovery and utilization

Update Time: 2019-04-10 Hits: 1193

User unit: Shandong Yantai Resort Auto Parts Co., Ltd. Commissioning time: July 2004 Waste heat source:
A cupola of the company produces a large amount of high-temperature flue gas (300-400 ℃), which is artificially mixed with a large amount of cold air to cool down and remove dust, and then discharged into the atmosphere, and a large amount of thermal energy is wasted.
Use of waste heat:
Using part of the cupola furnace flue gas waste heat to heat hot water for the entire factory staff to take a bath, the number of employees is 200, the bathhouse is open for two hours a day.
Basic data:
1. Flue gas temperature: 300 ° C 2. Number of employees: 200 people 3. Hot water temperature: 65 ° C
Waste heat recovery and utilization technology scheme:
Design a heat pipe gas-liquid heat exchanger. Due to the high temperature of the flue gas, in order to prevent the condensation section of the heat pipe from scaling, a set of water-immersed coil heat exchangers are installed in the water-side shell for secondary replacement The heating and hot water supply capacity is calculated based on the water consumption of 100 people per day.
