What is hotwell tank?
Hotwell. A Clayton Hotwell Tank is engineered as an atmospheric feedwater make-up and condensate receiver equipped with a water level control valve and a temperature regu- lating valve. Hotwells are available in several sizes for single and multiple Steam Generator installations.
Does a steam boiler need an expansion tank?
In most cases, a steam boiler will not require extra accessories. In contrast, a hot water boiler will typically require an expansion tank, a circulator, and a flow check valve. Most importantly, a hot water boiler will require a motorized pump.
What is the purpose of hotwell?
The condenser hotwell serves as a water reservoir for the turbine cycle. When hotwell level reaches the low point, a valve opens to supply make-up water to the cycle. When hotwell level reaches the high end of the level range, a dump valve opens to move the condensate from the hotwell to a condensate storage tank.
Where is hotwell located?
Hotwells is a district of the English port city of Bristol. It is located to the south of and below the high ground of Clifton, and directly to the north of the Floating Harbour….

Why is a hotwell heated?
The reason you want the hotwell to be “hot” is that what ever temperaure is lost to sub-cooling must be made up by burning fuel, coal in your case.
How much does a boiler expansion tank cost?
Materials. The cost of an expansion tank ranges from $40 to $200. Most newer expansion tanks are bladder or diaphragm type tanks, with a rubber bladder that expands and keeps water separate from the main tank.
What’s the purpose of an expansion tank on a boiler?
The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater, preventing excessive water pressure. If water pressure gets to high it can damage valves in plumbing fixtures, joints in supply pipes and the water heater itself.
How do you keep the condenser level on a hotwell?
Set Points Of Levels In Condenser Hot Well
- Generally we try to maintain hot well level at 0 MM or normal level.
- If hot well level falls below 0 mm, normal make up valve will open and allow DM water to condenser in order to maintain normal level.At Low level this normal make up valve will be fully opened.
What is hotwell in ship?
Cascade tank, also known as hot well, is a part of boiler feed water system. Water is pumped into the cascade tank from the feed water tank. The boiler water is treated in the cascade tank and the return from the steam heating system is also connected to the hot well.
What is the purpose of slop tank?
Slop tanks are the focal point of the Load-On-Top system used on crude oil tankers to prevent pollution of the sea. Design of these tanks and their operating procedures strongly affect the degree of oil-water separation achieved.
What is a hotwell on boilers?
noun. a tank or reservoir in which hot water is collected before being recirculated, especially condensed steam about to be returned to a boiler.
How is condensate moved from the Hotwell to the storage tank?
When hotwell level reaches the high end of the level range, a dump valve opens to move the condensate from the hotwell to a condensate storage tank. Water loss in the turbine cycle due to leakage, steam venting or other usage depletes make-up water.
What is the function of the condenser hotwell?
The condenser hotwell serves as a water reservoir for the turbine cycle. When hotwell level reaches the low point, a valve opens to supply make-up water to the cycle. When hotwell level reaches the high end of the level range, a dump valve opens to move the condensate from the hotwell to a condensate storage tank.

What happens if water is too cold on a Hotwell boiler?
Hotwell Water Tanks. The temperature of the water being fed to the boiler is of paramount importance. Water which is too cold may cause thermal shock and structural damage to the boiler, and will certainly have an adverse effect on the overall energy efficiency of the boiler.
