Description

The critical components of the glass furnace subject to corrosion/erosion are: the valve gate and the valve seat bottom and sides which can also be subject to warpage causing subsequent leakage and the furnace flues (or ducting). The Brayton System will be added to the glass furnace just downstream of the reversal valve. Hence, the inlet air to the flues will no longer be at ambient temperature but at a higher level between 800 to 1000/sup 0/F. Also, the exhaust gas for the Brayton System is required to be 1500 to 1600/sup 0/F at these locations. Thus, the flues and … continued below

Description

The critical components of the glass furnace subject to corrosion/erosion are: the valve gate and the valve seat bottom and sides which can also be subject to warpage causing subsequent leakage and the furnace flues (or ducting). The Brayton System will be added to the glass furnace just downstream of the reversal valve. Hence, the inlet air to the flues will no longer be at ambient temperature but at a higher level between 800 to 1000/sup 0/F. Also, the exhaust gas for the Brayton System is required to be 1500 to 1600/sup 0/F at these locations. Thus, the flues and valve components will be exposed to a much higher average temperature operating with the Brayton System. The possibility of cracking of the refractory linings and warpage and scaling of the switching valve, with consequent leakage to the exhaust stream should be avoided or decreased as much as feasible because of its effect of lowering the turbine inlet temperature and thus the total system value. On the inlet side, leakage dilutes the heat added to the air (which is preheated) and reduces the expected fuel savings. Assessment of such effects and determination of potential solutions and/or improvements in these areas is the purpose of this component system analysis and testing. The materials, mechanics and operations of the two areas of concern and the program for testing alternative approaches including test hardware, objectives, conditions and locations are described.
