I am trying to figure out a problem we are having with a steam boiler. First, it is a natural gas fueled boiler rated at 2,000,000 BTU. In the summer time, the boiler supplies heat to the indoor pool through a heat exchanger. There is approximately 10 ft of 1 inch black iron pipe feeding into the top of of the copper heat exchanger. The problem is that over a 2-year period the steam coming into the heat exchanger @ 40 psi has cut a hole into the heat exchanger. My question is does velocity have any part in this? Someone had told me that do to the size of the boiler (2,000,000 BTU) and the size of the pipe feeding the heat exchanger, the velocity of the of the steam is higher and therefore creating a hole in the heat exchanger. Is there a formula to figure this or can anyone just explain it to me. Thank you--Rick
