Nine sets of firied heater flue gas waste heat recovery of energy-saving renovation and analyses the energy saving effect

In May 2014, our company undertook 9 sets of fired heater flue gas waste heat recovery of energy-saving renovation project in anyang baoshun technology incorporated company. after the completion of reconstruction, though a year of actual operation test contrast, coal gas consumption has significantly reduced; Exhaust gas temperature the average recovery of 150-265 ℃;The air temperature rise an average of 200-330 ℃.Directly to save coal gas cost 3.88 million yuan each year, environmental protection and energy saving effect is remarkable, and get the each layer leadership's consistent high praise in baoshun.

1,The first set of reforming device:5 sets fired heater in wash oil workshop
Before transform conclusion: 5 tube furnace transform share amount of coke oven gas is: 1350 nm3 / h. After transform sharing amount of coke oven gas is: 988 nm3 / h. Energy saving efficiency is 26.6%. Exhaust temperature from 350-350 ℃ to 230-250 ℃; Combustion-supporting air temperature from room temperature to 330-360 ℃. Every year for the enterprise energy saving gas costs 1.44 million yuan.

2, The second set of reforming device: two sets fired heater in asphalt plant
Transform conclusion: the original single tube furnace with coke oven gas quantity before modification is: 726 nm3 / h. after Modified with coke oven gas amount is: 580 nm3 / h. Energy saving efficiency is 20%.Reduction exhaust temperature from 430 ℃ to 430 ℃;Preheat combustion-supporting air temperature from room temperature to 355 ℃.Every year for the enterprise energy saving gas costs 490000 yuan.

3, The third transformation device: 2 sets fired heater in tar workshop

Transform conclusion :two sets tube furnace with coke oven gas quantity before modification is: 2272 nm3 / h. after Modified with coke oven gas amount is: 1755 nm3 / h. Energy saving efficiency is 23%.Reduction exhaust temperature from 360 ℃ to 360 ℃;Preheat combustion-supporting air temperature from room temperature to 250 ℃.Every year for the enterprise energy saving gas costs 1.95 million yuan.
