Blowdown Heat Recovery

headerpenn

Now more than ever, rising fuel costs and marked downturns in the housing market have impacted our industry. Weaker demands for manufactured products and elevated production costs have left us all scrambling to operate more efficiently. Adopting energy saving practices in your production can have a huge positive impact.

For this reason, Penn & CCS have an engineered package that can have an extremely short pay-back, long life cycle, and immense residuals to offer to our clients.

pennStop pouring production money down the drain and let us show you how to recover those valuable production dollars with this remarkable package, tailored for your specific operating conditions.

Continuous blowdown enters tangentially, spinning around in the Flash Chamber. Flash steam is released in the center area and recycled into the Deaerator. Every pound of flash steam returns 1156 BTU’s into your system which, when taken back to the Deaerator is condensed. So you not only save BTU’s but also make-up water. The remainder of the blowdown water flows directly down to the second area of recovery, the spiral coil heat exchanger. The hot water flows around the coils and heats the make-up water which flows through the coils.

The Penn Flash Economizer is designed for efficient trouble-free operation. Note that the only area in which sludge can accumulate is below the heat transfer area, and there is no valve between the flash area and heat exchanger area to stick or clog. Maintenance is simple with the Flash Economizer. The unit is flanged to simply drop out the lower spiral coil section, clean the copper or stainless coils, and place the unit back in operation without ever having to shut the boiler down.

 

Contact CCS today to recieve a Blowdown Heat Recovery Energy Survey and start cutting the bottom line.

 

Sample Energy Survey:

A 40,000 #/Hr. boiler with a typical blowdown rate of 7% will generate 2,800 #/Hr. Blowdown to Heat Recovery System. Entering at 115 PSIG. This gives 12.8% Flash Steam, Flashing to 5 PSIG in Heat Recovery System gives 358 Flashed Steam #/Hr.

HEAT RECOVERY FROM FLASH STEAM                                                           

358 #/Hr. Steam x 1,156 Btu’s/# gives 414,310  Btu’s/Hr. recovered. Btu’s/Hr.  414,310 / Million Btu’s / 80%  Boiler Efficiency x $10.00 Cost Fuel/million Btu’s

ANTICIPATED HOURLY SAVINGS FROM FLASH STEAM …………$5.18

HEAT RECOVERY FROM WASTE WATER (   228  F   -  90  F ) 2,442 #/Hr remaining. 138 DT  F change in temperature = 336,941 Btu’s/Hr. btu’s/hr. 336,941 / Million Btu’s / 80%  Boiler Efficiency x $10.00 Cost Fuel/million Btu’s    

ANTICIPATED HOURLY SAVINGS FROM WASTE WATER …………$4.21     

TOTAL HOURLY SAVINGS FROM Heat Recovery System……………………$9.39 / hr savings

Heat Recovery Survey - Approx. $1,578 / week - $6,832 / month - year / $82,000
