Blowdown Equipment
When a boiler is generating steam, the feedwater continuously carries dissolved mineral matter into the unit. To prevent an excessive accumulation of dissolved and undissolved solids which interfere with proper boiler operation, a blowdown program should be established. Blowdown separators take water from the boiler during blowdown and reduce it to atmospheric pressure for disposal. Blowdown heat recovery systems recover up to 90% of the heat energy that would otherwise be lost down the drain. The recovered heat is used to pre-heat boiler make-up water before it enters the deaerator, and for low pressure steam to heat water inside the deaerator, which reduces the cost to run the deaerator and improves overall boiler efficiency.
