What is meant by blowdown process?

What is meant by blowdown process?

Blowdown refers to removal of water from the cooling tower sump, as evaporation continuously concentrates the cooling water with dissolved minerals.

What are the risks of carrying out boiler blowdown?

High levels of these dissolved solids can result in boiler water carryover into the steam system which may cause severe damage to equipment that uses steam such as steam turbines, heat exchangers and steam traps. Surface blowdown is the method used to remove these dissolved solids.

How do you treat a boiler blowdown?

There are three ways to minimize boiler blowdown that will save water for your boiler plant. Automate Surface Blowdown • Proper Pre-treatment • Condensate Recovery Automating Surface Blowdown Automating the surface blowdown allows for the highest TDS (total dissolved solids) portion of the boiler water to be purged.

What is purpose of boiler?

Why use a Boiler? Boilers are used to produce steam. The generation part of a steam system uses a boiler to add energy to a feedwater supply to generate steam. The energy is released from the combustion of fossil fuels or from process waste heat.

Can I leave my boiler on continuously?

This is a common question that we get here at Duffy Heating, and the short answer is no. It is not more efficient to have your boiler on constantly at a low temperature. The idea that it saves you money seems to be an urban myth that grew in popularity.

How often should you have to Repressurise a boiler?

Read our guide on how to repressurise your system. If pressure rises by more than 1 bar when the heating is up to temperature then the expansion vessel may require repressurising. This will require a service engineer. The pressure in the system will usually require topping up once or twice a year.

Is it dangerous if boiler pressure is too low?

If the boiler pressure is too high, there’s an increased chance of leaks developing in the system. But if boiler pressure is too low, the system won’t work as well. So keeping the correct boiler pressure is important to make sure that your system heats your home efficiently.

Does bleeding radiators affect boiler pressure?

Bleeding radiators If you bled your radiators recently, you may have lost some pressure. That’s because, when you bleed a radiator, air is released, which lowers the pressure in your boiler system.

Do I bleed radiators with boiler on or off?

Turn off your heating. You can’t bleed a radiator when the heating is on, as it may be too hot to touch. You could also get hot water spraying out of the radiator. Use your radiator key to turn the valve at the top of the radiator.

How do I bleed the pressure on my boiler?

How to bleed your radiators

1. Attach the radiator key into the square section in the centre of the radiator valve.
2. Use a cloth or strong tissue paper to hold the radiator key.
3. Have another cloth under the radiator valve to catch any drips.
4. Turn the radiator key slowly in an anti-clockwise direction.
