Few answers to this, dependant on system type + fittings etc. the most common is an old system, in need of a good clean- corrosion of the metals cause by the oxygen in water reacting with iron in rads, you get ironoxide (rust) and hydrogen. so the most common answer is its not air its hydrogen, be careful but you can open a bleed on a rad slowly and hold a match, if it lights, I was right =p
Natural draft in a boiler is the airflow generated by the temperature difference between the inside and outside of the boiler. As the temperature inside the boiler increases, the air becomes less dense and rises, creating a vacuum that draws in fresh air for combustion. This natural process helps to maintain steady and efficient combustion in the boiler.
Less excess air is needed during low boiler loads because the combustion process at lower loads is less efficient. Excess air helps ensure complete combustion in the furnace by providing oxygen for the fuel to burn. However, using too much excess air can lead to energy loss and increased emissions.
Add water to the boiler. You should have an automatic pressure reducing water make up valve, somewhere near the boiler. If it feeds directly into the boiler, make sure the boiler is cool when you add. Normal pressure on a cool boiler should be around 12 psi. The pressure will rise as the water is heated. You need a minimum of 1/2 psi for every foot of rise in the loop. So 12 psi in the basement will allow most systems to have a rise of appx 24 feet to the highest strip of baseboard. Remember, the pressure relief valve on the boiler lifts at 30 psi, so you need to stay well below that when the boiler is up to temperature.
A damper in a boiler is a device that regulates air flow into the combustion chamber. It helps control the amount of oxygen available for combustion, thereby maintaining the desired temperature and efficiency of the boiler. By adjusting the damper, the operator can fine-tune the combustion process for optimal performance.
Boiler preservation is necessary to prevent corrosion and rust formation when the boiler is not in operation for an extended period. It helps protect the internal surfaces of the boiler from damage and ensures that it can be safely and efficiently restarted when needed. Proper preservation also helps extend the lifespan of the boiler.
None. Probably the home was built for forced air and converted to boiler/baseboard heating.
its easy if you do this they wont you to make a line for the pipes so they go in a line to the boiler so you can get air into the boiler
ATMOSPHERIC BOILERa boiler on which combustion air/flue gases are drawn through the boiler without a fan.(Taken directly from the Crown Boiler Co. web-site.)

A furnace heats air; a boiler heats water. --The HVAC Veteran
Because it has air in it.

The combustion air will not be able to go out the chimney. Since it has to go somewhere it will leak out the boiler into the boilerroom. If the boiler is air tight the pressure inside the boiler furnace will become high enough that the air will surge or run backwards out the forced air fan. This could lead to combustion outside the boiler, explosion or at least filling the boiler room with smoke and poisonous gasses. The flue on our gas fired hot water system once became jammed shut. It was the smell of incomplete combustion that alerted me to a problem. If it had happened when everyone was asleep or no one was home, the house would have filled with carbon dioxide.
To calculate excess air in a boiler, you first need to determine the theoretical air requirement for complete combustion based on the fuel's composition. Then, measure the actual amount of air supplied to the boiler. The excess air percentage can be calculated using the formula: [ \text{Excess Air (%)} = \left( \frac{\text{Actual Air} - \text{Theoretical Air}}{\text{Theoretical Air}} \right) \times 100 ] This calculation helps in optimizing combustion efficiency and reducing emissions.
It's used to remove air and gasses from a boiler system.
Labda is defined as the ratio of actul air ti theoritical air.
