BOILER BLOWDOWN EQUIPMENT
Madden Engineered Products, LLC. was originally the P.E. Madden Co. of Chicago, IL. which started in the industrial water treatment chemical business, making boiler continuous blowdown flow control and heat recovery equipment in the 1930s…. we’ve been doing this for a long time.
At Madden, we have nearly everything to service your boiler blowdown needs. Madden boiler blowdown equipment can hold boiler blowdown, separate boiler blowdown to steam and wastewater, cool boiler blowdown, control continuous blowdown flow rate, and even recover otherwise lost heat from the blowdown. All of our steam equipment pressure vessels are ASME code stamped for Section VIII, Division 1 requirements and come with a National Board serial number and U-1 form.
Heat Recovery Systems
Madden heat recovery systems are designed to recover energy in otherwise lost BTU’s due to steam ventilation and convection cooling. If you have an application where surface or top continuous blowdown is at least 300 PPH, then there is a Madden Heat Recovery System waiting to save you money. Madden HC and HV units are designed to separate the hot boiler blowdown into flash steam. This flash steam can be recovered and sent back to your deaerator (D/A) tank to be used to heat boiler make up water. The rest of the blowdown is then cooled with counter flowing cooling water, thus allowing it to be safely put into the city sewer.

Boiler Blowdown Tanks
Blowdown tanks cool your intermittent hot boiler blowdown via the flash steam principle as well as convection cooling. When the hot boiler blowoff enters the tank, the pressure change turns some of the blowdown into flash steam. This is then safely vented into the atmosphere. The rest then cools over a 6-12 hour period before being safely dumped into the city sewer on the next blowdown cycle.
Unless otherwise specified, Madden boiler blowoff tanks are designed to meet the latest NB-27 standards.
