FAQ

Really need to sort this :-)

Why can't you bleed the radiator? Do you have a radiator key? Is the valve stuck or missing? If so, it really needs fixed. The valve is also a safety thing. Bleeding the boiler will remove trapped air from the system overall and should help. But then, when it's fired back up, all the radiators should also be bled. As to the automatic refill, it depends on the system. Look at the inlet water pipe (usually directly above the boiler) and see whether the valve is opened or closed. If it's already opened, the system should refill automatically after bleeding. If the valve is closed, you'll have to manually open it to refill the boiler, then close it again when the boiler is filled.

which kind of water tubes ( beside those with smooth surface) are used for boilers?

Boilers also use finned tubes and studded tubes. These are typically used in the convection section of the boiler and the super heater. They can't be used in the fire box area due to the radiant heat flux. It will cause damage to the thin fins or studs.

why is the line for the hot water coming from the boiler not hot, but the return line is hot, already changed the circulator pump,and drained the system, but still not getting hot water to circulate ?

Recheck the rotation of the pump. some systems usually pump the return into the boiler and the supply is leaving on the other side. When changing a pump, or opening the system ...the pumps prime can be lost. Find a way to vent air out of the volute of the pump after you check for proper rotation. Start and stop the pump and listen for air bubbles. Also check the ampere draw on the pump. if its rated for example 6.6 amperes, then a pump that is doing its job pumping will be pulling close to or somewhere near the 6.6 it is rated at or (Full Load Amperes.)

What is boiler efficiency? What is thermal efficiency of an steam engine?

Boiler efficiency is the ratio, often expressed as a percentage: (heat energy out)/(heat energy in) of the boiler. The difference between the two arises mainly from the heat escaping up the chimney stack, although there's also loss due to radiation and convection from the boiler surfaces. In the case of a steam engine the thermal efficiency is the ratio (mechanical energy out)/(heat energy in). A large portion of the difference between the two arises from thermodynamic considerations which do not affect a boiler since it performs no energy conversion.

If it has any other usage other than supplying air to the combustion chamber? Will it play any role in allowing a quantity of air to the stack for clearing the exhaust?

yes it help to keep the exhaust exhausting by creating positive pressure in the stack. I am assuming you had problems with negative pressure and it backing up and shutting down your boiler? Forced draft: Draft is obtained by forcing air into the furnace by means of a fan (FD fan) and ductwork. Air is often passed through an air heater; which, as the name suggests, heats the air going into the furnace in order to increase the overall efficiency of the boiler. Dampers are used to control the quantity of air admitted to the furnace. Forced draft furnaces usually have a positive pressure. Thats the definition, But yes it provides the combustion air if you have limited breathing room for you boiler , and keep the positive pressure in your stack.

Can I adjust this water feeder?

Chances are the float is dirty which will cause overfilling. My old boiler had the same water feeder and I had to take it apart a couple times a year to clean the float. Rust and scale from the boiler water can stick to the float and housing. Refer to the web page below which has a link to a drawing that shows how to disassemble the unit. It is not a difficult task and be careful taking it apart because there is an O-ring that can be damaged. Clean all the parts with soap and water then reassemble. If it still overfills then it might be time to replace the unit.

what is the meaning of second hand boiler or what are the all types of boilers?

Well,second hand means not new or used. a Boiler is a container used to boil water or any liquid. You can use an element that is heated by means of electricity or you can make a fire under the boiler to heat it. so the geyser you get your hotwater from in your house come from a electrical power boiler that is inside a insolated sealed housing to prevent heat loss. On coal fire power stations they make use of coal to super heat the boiler in order to produce steam to drive the turbines.
