New Alarm Reduces Boiler Failures, Diesel Failures And Repair Costs
—Free Brochure Available Since nearly the beginning of shipboard and power station boiler use, little thought or consideration has been given to boiler protection from oily condensate return caused by seal failure from the turbines.
The U.S. Navy, to protect their boilers, used double-walled boiler tubes. The weight increase, however, caused weight problems in the submarine fleet. In addition, initial cost of manufacturing was much higher than for standard systems.
Where the steam pressure is higher than the lubrication pressure, no problem exists until routine boiler shutdown, then leakage may occur and is not discovered until boiler tube failure from lack of heat transfer.
Biospherics Incorporated, Rockville, Md., has now developed a selfcleaning, on-line, oil-in-water alarm which can withstand temperatures up to 250° F. This unit, placed directly into the condensate return lines, will alarm and trigger switch closure on as little as 2ppm oil-inwater, thus saving the boiler accidental damage.
In addition, damage to diesel engine cylinder walls is often due to "hot spots" created by oily deposits caused by seal or gasket failure, allowing lubrication oil to enter the cooling jackets and act as an insulator.
The BA-200 HT, introduced by Biospherics, is said to be ideal for diesel protection, and is already installed on the diesel engines of the Canadian Coast Guard's Ice Breakers.
The unit is unaffected by common coolant additives. Although this model is a commercial one, it was found to be able to withstand the continuous shock and vibration of the Bombardier engines used in this class of vessel.
