Boiler Blowdown Separators

The HBC Blowdown Separator is designed to take water from the boiler during blowdown and reduce it to atmospheric pressure for disposal. The HBC Separator accomplishes this by separating the subsequent flashed steam from the hot water. As the blowdown enters the vessel, it is forced into a centrifugal pattern by means of a striking plate. The steam is vented to the atmosphere through a top connection. The HBC Blowdown Separator provides an economical means of safe boiler blowdown.

"CP" Type

The "CP" boiler consists of two parallel drums, configured such that the upper drum is considerably longer than the lower drum. In addition the boiler has two (2) lower sidewall headers that run the complete length of the boiler setting and help to configure the sidewalls of the boiler's furnace. The "CP" type boiler has been consistently used for over 70 years in typical solid fuel fired configurations for both saturated and superheated steam boilers. The original boilers of this design consisted of tube and tile construction. However, due to engineering advancements in waterwall membrane construction, the furnace sidewalls are now of the membrane design.
