Float Glass Kiln Waste Heat Boiler

Waste gases leaving float glass furnace at temperature ranging from 450 to 540℃ have a high potential for heat recovery. ZBG developed float glass kiln waste heat boiler to fully recycle high temperature flue gas from glass kiln and further its waste heat utilization more than 70%.

Low resistance, low energy consumption

Equal velocity and low velocity design can ensure the boiler body resistance less than 900Pa, which is in favor of reducing system power consumption.

Good sealing, good thermal transferring efficiency

Gas tight side wall of water wall construction to reduce boiler air leakage.

Long operation time, running cost reduction

The furnace with an inverted “U” shaped layout overcomes the shortcomings in structure and operation. Firm structure and high quality can serve for more than 10 years in glass factory.
