How does a back boiler work scientifically?

A boiler works by heating water in an enclosed space. The expansion of water molecules as it transforms from a liquid state into a gaseous one causes the boiler to generate a vast amount of pressure. This is generally the science behind a back boiler.


Does boiler pressure affect water temperature?

Boiler pressure does not directly affect water temperature. Water temperature is primarily controlled by the thermostat setting on the boiler. However, excessive boiler pressure can lead to other issues such as leaks and inefficiency in heating the water.


What are the consequences of low alkalinity in boiler water?

Low alkalinity in boiler water can lead to increased corrosion of metal surfaces, as alkalinity helps to maintain a stable pH level. This can result in damage to the boiler components and decreased efficiency of the system. Additionally, low alkalinity can also lead to foaming and carryover in the boiler, which can cause operational issues and reduce the overall effectiveness of the boiler.


How do you raise the pressure system on the baseboard heater?

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 low pressure steam boiler has a maximum allowable working pressure of up to?

The maximum allowable working pressure for a low pressure steam boiler is typically up to 15 psi (pounds per square inch). This indicates the highest pressure level at which the boiler can operate safely without the risk of failure or damage. It is important to adhere to the manufacturer's specified limits to maintain the boiler's safety and functionality.

What are the boiler protections in power plant?

Common boiler protections in a power plant include high steam pressure trip, low steam pressure trip, high furnace pressure trip, low water level trip, and flame failure trip. These protections help prevent dangerous situations such as overpressure, low water conditions, and flameout, which could lead to equipment damage or accidents. Regular testing and maintenance of these protections are essential for safe and reliable operation of the boiler.


What is difference between 500MW boiler 660MW boiler?

500 MW Boiler is sub-critical Boiler which generates steam at pressure lower than the critical pressure ie below 221.2 kg/sqcm. where as the 660 MW boiler is super critical boiler which operates steam pressure above critical pressure.


Why is the steam pressure coming out of the boiler low?

Depends on the situation! It may be needed at only a low pressure. Otherwise it may be the result of reduced heat input or of the input of cold feed-water.
