Fire suppression tank

tk_3

I am thinking about replacing a boiler for a fire suppression tank. The tank is a 200,000 gallon tank. Looking at the piping I assume the boiler heats a coil in the tank. My big concern is there is no coil. The piping has valve which do not close. I don't mind losing the water in a coil and replace the valve. I do not want 200k gallons of water on the floor.

Could it be that...

The water in the tank and the boiler are one in the same?

May we assume the tank is heated by this boiler to prevent freezing?

If so, does the boiler do any other "work"?

If there is no coil in the tank

you would do well to add one. You certainly do not want a lot of fresh water going thru the boiler- it will eat the boiler for breakfast, lunch and dinner.

If the valve won't close, you'll probably have to drain the tank. Seems wasteful, but the alternative is worse.

Is this a steam or hot-water boiler?

Direct heating for freeze protection

Hi Jason,

The short answer is yes, it's very possible that this is a direct heating application, for freeze protection only.

What model of heater, or boiler are you replacing?

boiler for holding tank

email your phone number and I will advise on what to look at. We have done 10 plus both steam and water to water always via a heat exchanger

Freeze seal?

If the piping can withstand it, how about using a freeze seal. Freeze a plug of water, cut the pipe, insert a valve let the water thaw.

Hi Ken,

I'm hoping Jason will reply back with the heater make and model. If, for example, this was one of our larger direct heating models, he could be dealing with a 3", or 4" shut off valve. If the application has a stand pipe as well, there could be quite a bit of standing head pressure involved in holding back the tide.

Think of the Ents releasing the river....
