If live steam is supplied directly to the tank heating coils; the collected drains in the 'clean' section of the contaminated drain inspection tank are removed directly to the _______________.
AI Explanation
The correct answer is B) atmospheric drain tank.
When live steam is supplied directly to tank heating coils, the collected drains in the 'clean' section of the contaminated drain inspection tank should be removed directly to the atmospheric drain tank. This is because the atmospheric drain tank is designed to collect and store condensate and other low-pressure drainage, which would be the appropriate destination for these clean drains.
The other options are incorrect because: A) the main and/or auxiliary condenser is used for higher-pressure steam, not low-pressure drainage; C) the makeup feed water tank is for replenishing the boiler feed water, not for collecting tank drains; and D) the deaerating feed water heater is for removing dissolved gases from the feed water, not for collecting tank drains.
