Exhaust Gas Heat Recover Boilers For Glass Kilns

Exhaust Gas Heat Recover Boilers For Glass Kilns

The exhaust gas heat recovery boiler adopts forced circulation, that is, steam and water working fluid are driven by external force (feed water pump, hot water circulation pump) in the pipe. This can make the heating surface layout very compact and without any restrictions.

Heating surface of exhaust gas boiler consists of 2 parts economizer and evaporator. According to the calculation of heat balance of waste heat boiler, the single waste heat boiler should reach 6.0t/h steam output, and the waste heat boiler must set economizer section, and the feedwater absorbs the low and medium energy of exhaust gas. On the one hand, it can increase the feed water temperature and the steam output of the waste heat boiler; on the other hand, it can improve the effective utilization rate of the heating surface in the evaporator section.

In order to improve the heat transfer temperature and pressure of the economizer, the economizer section adopts a countercurrent arrangement, that is, the working medium and the exhaust gas flow direction are opposite, and the evaporator section is still arranged in a downstream flow.

In summary, a waste heat boiler is installed in the flue duct of the kiln tail to achieve the purpose of recovering waste heat of flue gas and protecting the environment. It is of great practical significance to effectively reduce energy consumption and promote the sustainable development of renewable energy.

The location of Kiln Waste Heat Boiler

Under normal conditions, the waste heat boiler of kiln furnace locates in front of the flap valve in the main underground flue, and draws the hot flue gas from underground. After heat transfer and cooling in the waste heat recovery system, the temperature of flue gas is reduced from 260℃-300℃ to about 140℃-160℃. The flue gas is discharged into the reserved hole on the original chimney through the induced draft fan of the waste heat boiler outlet, and then discharge into the atmosphere through the chimney.

Benefits of Kiln Waste Heat Boiler 

1.Highly reliable in operation and robust in construction.

2.Quick Payback Returns are achieved.

3.One time investment with lifetime returns.

4.No combustion, No emission hence Eco-friendly.

5.Energy being put to use, which was getting wasted anyway.
