Lyons Boiler Plant Water Treatment.pdf

Lyons Boiler Plant

Lyons boiler plant consists of 5 Cleaver Brook CB200‐700 boilers. Each boiler is fed from a batch tank for chemical treatment of the boiler. We have a new injection quill on our D.A. tank and our water softeners are producing quality soft water with no hardness detected. There is a steam absorber on campus for the chilled water loop, but it is rarely used. Most of our steam is used for heat and hot water on campus.

1. Sample Stations with coolers are located throughout the plant for proper sampling of the water.

2. Boiler water is tested every day before 10am

3. Conductivity is tested at a minimum once per shift, if not more to maintain proper conductivity on all online boilers.

4. We run 1 boiler in the summer months, and 2 boilers in the wintertime.

5. There is a steam absorber on campus for the chilled water loop, but it is rarely used. Most of our steam is used for heat and hot water on campus.

6. Our last DO test performed on the D.A. tank was performed in January with the sulfite turned off for 24hrs and the result was 35ppb, indicating our D.A. tank nozzles are operating as intended.

7. Our boilers are cleaned professionally every summer by the local Cleaver Brooks dealer. We hydro the boiler to indicate any leaking tubes and have them repaired promptly prior to closing the boiler.

8. We are controlling boiler conductivity by hand as our TDS controllers do not function properly, they will be repaired and re piped to accommodate automatic operation again soon.

9. Batch tank chemical pumps are Neptune pump 500‐A‐N3 SS, 1GPH@1000psi

10.

We run chem aqua chemicals now and they are as follows…

CA 12800 for deposit control

CA 11540 For alkalinity booster

CA 10270 as an oxygen scavenger

CA 18104 for return line treatment

a) CA18104 and CA12800 are mixed in the batch tank after taking water samples and fed accordingly.

b) CA11540 and CA10270 are fed directly into the DA tank via pump and quill, and pump adjustments are made according to the daily water test results.

c) A company driver will deliver our chemicals in drums and pump them into the appropriate tanks as required and leave the bill of lading with the operator on shift. Two tanks are located on the lower level with access to run hoses and the other two tanks are on the street level with the ability to roll a drum near the storage tanks and pump.
