What is the purpose of auxiliary boiler in power plant?
The auxiliary boilers are the initiation point in the thermal power plant. From works of cleaning fluid pipes, heating of fuels to a point, bringing the thermal plant to a minimum temperature is all done with the help of auxiliary boilers.
What is auxiliary steam in power plant?
5. The auxiliary steam generator system as claimed in claim 1, wherein the feed-water extraction line is connected to an extraction point of the feed-water pump. 6. The auxiliary steam generator system as claimed in claim 1, wherein use in a gas and steam turbine power plant. 8.
Which of the following is the auxiliaries of the boiler?
The following boiler auxiliaries are required by the British Boiler Regulations: (1) safety valves, (2) water gauges, (3) boiler feed check valve, (4) blow-down valve, (5) low-water-level safety device, and (6) main stop valve.
How do I start my auxiliary boiler?
Starting Boiler and Pressure Rise
- Check that the gauge board valve and pressure gauge valves are opened.
- Check that the air valve is open if the boiler pressure is below 1.0 bar.
- Start the burner on manual control and on low load.
- Drain via the blow down valves if the water level is too high.
What is main boiler?
A system boiler needs to be installed within a heating system which also includes a hot water cylinder. Main system boilers are efficient and budget-friendly solutions for homes with up to 15 radiators.
What is a composite boiler?
marine. A firetube boiler which can generate steam by oil firing or the use of diesel engine exhaust gas.
What is the difference between auxiliary boiler and donkey boiler?
auxiliary boiler: An auxiliary boiler, on a steam ship, supplies steam that is not used for main propulsion, but is necessary for some part of the essential machinery. A composite auxiliary boiler does this, using waste heat from the main engines when at sea, or is separately fired when acting as a donkey boiler.
What is the difference between the auxiliary boiler and the exhaust gas boiler?
The heated exhaust gas from the engines (exhaust gas boiler) acts as a source of energy for generating this steam or thermal oil. Other auxiliary boilers are fired with oil or gas. A large number of valves are necessary to operate the boiler: Safety valves – for protection against excessive pressure.
Hope, it shall serve your purpose. As the name suggests, an auxiliary boiler is small boiler in addition to the main boiler in a power plant which is basically used to serve auxiliary purposes of the plant rather than being used for putting the steam in the Turbine for power generation.
What Boiler Auxiliaries are required by the British boiler regulations?
The following boiler auxiliaries are required by the British Boiler Regulations: (1) safety valves, (2) water gauges, (3) boiler feed check valve, (4) blow-down valve, (5) low-water-level safety device, and (6) main stop valve. In a boiler, two safety valves must be provided, each capable of discharging the peak evaporation of the boiler.
What are fuel-oil-fired boilers used for in power plants?
The plants I worked in used fuel-oil-fired boilers to provide steam during startups and shutdowns to various systems such as sealing steam, turbine-driven pumps and fans, vacuum jets, etc. During winter they were used to supply building heating steam if the unit were offline.
What is the source of auxiliary steam in a steam turbine?
Initially, when the CRH pressure is not developed, the source of auxiliary steam must be from MS. When the CRH steam pressure is established, then it is switched over to CRH as the source. Whenever CRH is selected, the PRV in the MS line must be closed following a ramp circuit.
