	1. Washing drum 5 bubble cap trays are damaged. Now they're being replaced with sieve trays. What are the things to be checked during this change over? 2. What will be the change in tube surface temp when Refractory is changed in a flat surface / cylindrical surface (like SRU Thermal Oxidizer / FCC Regenerator)? Original refractory TC - 0.4 W/m. K, proposed Refractory TC - 1.0 W/m. K Thickness - 90 mm Flue gas temp - 900 deg C, Amb Air - 40 deg C. Others can be varied as per reqd.

	A1. Make sure no-one is inside it when the lid is put back on. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	You should stop wasting Our/your time here and ask the tray supplier directly these questions. He is the only one who has a financial stake in the outcome.
