: We have a low pressure boiler operated at 165 psig. Is continuous blowdown needed as long as the boiler water TDS is under the recommended values set by ASME/ABMA.
No. You can use an intermittent controller to maintain TDS below recommended levels or you can use a very tight chemistry monitoring program and calculate the necessary values for timed blowdowns to maintain TDS.
