What are Appropriate Boiler Blowdown Design Parameters? – Designing recommendations for both continuous surface and intermittent bottom blowdown

When designing a new boiler room or making changes to an existing one, one small but pertinent aspect of this is coming up with the appropriate blowdown design percentage for both surface blowdown and bottom blowdown. What is a good rule of thumb to be used as the minimum amount of blowdown to design around? How much is too much? This Madden Manufacturing article will walk through these providing guidance to the questions and explaining why you need to be blowing down your boiler(s) in the first place.

Have your boiler blowdown waste water pay for boiler fuel costs: Boiler blowdown heat recovery systems by Madden

Boiler rooms that total to 250 BHP or higher (or think steam production around 10,000 PPH or higher) often utilize continuous surface blow down on top of the standard intermittent bottom blowdown process. Continuously blowing down surface water helps keep the boiler free from scale build up on the water or fire tubes and keeps suspended solids and other impurities from hindering efficient boiler operation.

How to recover and reuse heat from boiler blowdown water: Part 2, focusing on Madden’s lower vessel of a HV model heat recovery system, the heat excha

In our most recent blog posting we discussed how Madden Manufacturing’s vertical boiler blowdown heat recovery systems recover heat from your boiler’s continuous surface water blowdown. In that blog we focused on the operation of the upper portion, the flash tank, and how it results in saving on fuel costs.

In this blog post we are now going to discuss how the lower vessel, the heat exchanger, operates, resulting in fuel savings.

How to recover and reuse heat from boiler blowdown water: Part 1, focusing on Madden’s upper vessel of a HV model heat recovery system, the flash tank

Madden Manufacturing designs and builds simple, rugged heat recovery systems for boiler and steam generator continuous blowdown. Our units safely and legally dispose of the boiler’s dirty surface water blowdown, all while recovering the heat and saving you money.

We offer two different styles, the vertical HV system and the horizontal HC system. Our boiler blowdown heat recovery products offer great performance and efficient economical return on your investment. Most units will pay for themselves in less than a year.

What are the advantages of using a vertical heat exchanger in a boiler blowdown heat recovery system

When developing a P & ID and/or floor plan for a boiler room installation, horizontal floor space is usually given a lot of thought and attention. Vertically designed boiler equipment allows for more efficient spacing in your boiler room and is also much easier to incorporate later on if  a piece of equipment is being added to a preexisting boiler room.

Madden Manufacturing’s HV series heat recovery systems are designed to operate with a small footprint. The unit itself stands on a 24” X 24” pad and other than where you choose to install the inlet manifold, the rest of the unit is does not take up much more than 2 square feet the whole way up.

What are B.T.U’s and why are they important in boiler blowdown processes and cost savings?

B.T.U stands for British thermal unit and is commonly defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. Other than safety measures, BTU’s are arguably the most important factor to spend time and energy on when it comes to your boiler process. In the boiler room, B.T.U’s are their own form of currency. It takes a lot of energy to produce heat to boil water and to keep it boiling. The more efficient the boiler operator can be, the less energy, heat, and fuel are needed to produce steam.

Most boiler applications run 24/7/365. The energy to produce heat can come from natural gas, electric, or coal, among other sources and processes. So the smallest amount of B.T.U’s you can save will add up to big savings to your fiscal year’s bottom line.
