Adjustment and Improvement on Burner Area Furnace Near-wall Reducing Flue Gas for Coal Firing Boiler

Furnace near-wall reducing flue gas is the most important cause leading to boiler furnace high temperature corrosion. It first introduces the furnace near-wall flue gas measurement and high temperature corrosion tendency evaluation for 1025t/h boiler made by Shanghai Boiler Plant, and then expatiates on the adjustment work for improving furnace near-wall reducing flue gas, the adjustment work has improved the boiler furnace near-wall reducing flue gas, at last analyzes the furnace flue gas status basing on measurement and adjustment work, and gives correlative suggestions for the boiler.
