What is the working pressure of a Loeffler boiler?
The Loeffler boiler has the capability to generate 100 tons/hour of steam at a temperature of 500° C and a pressure of 140 bar.
What is feature of the Loeffler boiler?
The novel feature of the Loeffler Boiler is to evaporate water solely by means of superheated steam. The furnace heat is supplied only to economiser and superheater. In other words, steam is used as a heat absorbing medium.
Which steam is generated in Loeffler boiler?
Loeffler boiler is a water tube boiler used for generating steam by the burning of fuel which is coal and further that is used for the generation of power.
Why does a boiler need high pressure?
An efficient boiler uses as much of the heat from the combustion as possible. A low stack loss temperature means effective heat transfer and less heat loss. To avoid stack loss, high pressure boilers control the amount of air to avoid excess air, which can cause stack loss.
Is Loeffler boiler is a natural circulation boiler?
Loeffler Boiler is a High-Pressure, forced-circulation, water-tube boiler.
At what temperature is the water is convection superheater is heated of Loeffler boiler?
At what temperature is the water in convection super heater is heated of Loffler boiler? Explanation: Steam coming out of the radiant super heater enters the convection where it is finally heated to the desired temperature of 500°C.
Which safety valve is used on high pressure boilers?
Relief valves are used in the high pressure boiler. High and low pressure boilers use pressure relieve valves. The pressure is maintained by releasing excess pressure.
Why starting valve is closed and valve 2 is opened while taking boiler on range in Benson boiler?
Explanation: The boiler is started from cold by circulating the feed water from the hot well by operating the starting valve. While taking the boiler on range, starting valve is closed and valve 2 is opened. This method avoids excessive heating of tubes.
What is the correct pressure for a boiler?
between 1 and 1.5 bar
A. The pressure on a boiler should sit between 1 and 1.5 bar. Most manufacturers recommend an optimal working pressure of 1.3 bar.
What PSI should a boiler run at?
In most cases, it should rise to about 20 psi while its heating element operates. That’s optimal at normal temperatures. Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at which point seals can begin to fail.
Why starting valve is closed and valve 2 is opened?
In what form are the boiler’s tube arrange in Lamont boiler?…
| Q. | Why starting valve is closed and valve 2 is opened while taking boiler on range in Benson boiler? |
|---|---|
| A. | avoid excessive heating of tube |
| B. | to maintain the constant flow of water |
| C. | to avoid pressure built up in tubes |
| D. | to avoid pipe leakages at joints |
Which safety valve is used on high pressure boiler?
What happens if boiler has too much pressure?
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.
