What is main purpose of refractories of boiler furnace?
one of the main purpose of refractories in the boiler furnace is to
When are superheater safety valves set to open?
after the main safety valves are open
What is main steam stop valve?
Used in power generation. When steam turbine is on-line the Main Steam Stop Valve is fully open. When offline it is closed. Steam to turbine is controlled thru control valves after Main Steam Stop Valve
What is the function of economizer in bent tube boiler?
The flue gases, after leaving the main boiler and the superheater, will still be hot. The energy in these flue gases are used to preheat the already preheated feed water once more by means of the economizer. The economizer is a heat exchanger mounted in the first part of the chimney to improve the thermal efficiency of the boiler. In broad terms a 10°C increase in feed water temperature entering the boiler will give an efficiency improvement of 2% of last mentioned.
Boiler drum which chemicals are using?
chemical is used in sub critical boiler that is tri sodium phosphate added in durm. The main purpose is raise in pH value , salt is converted in to sludge form
What is Auxiliary Boiler?
An auxiliary boiler is a secondary boiler used to support the main boiler in a steam power plant or marine vessel. It is often used when the main boiler is unable to meet the steam demands, providing additional steam capacity. Auxiliary boilers can also be used for heating purposes during maintenance or downtime of the main boiler.
What is the purpose of collision valve in fire line on ship?
A valve will be fitted so that if part of the fire main is damaged it can be isolated from the supply. That way the rest of the main is still usable and can be used for firefighting.
What are the types of once through boilers?
Benson Boiler , Sulzer boiler are the main subtypes of once-through boiler
What is the main purpose of a valve spring?
The main purpose of a valve spring is to maintain pressure and ensure that the valves close properly after they have been opened by the camshaft. It helps keep the valves in contact with the camshaft lobes and prevents them from floating or bouncing at high engine speeds. Ultimately, this allows for efficient and precise control of the engine's valve timing and operation.
Auxiliary steam stop valve?
It is a stop valve placed on an auxiliary piece of equipment. Or it could be placed at the steam main to feed an auxiliary steam system (heating, auxiliary pumping. etc.). It is not the Main steam stop for the boiler or the prime mover (engine, turbine, process), it is for a secondary service.
What is the main purpose of an inlet valve?
it opens and lets the fuel and air mixture into the cylinder head INLET VALVES
What is the blow cock?
A "blowcock", also known as a "blow-off valve" is a cock (valve) in the blow-off pipe of a boiler. Since blow-off valves are installed at low points of the boiler water system, it is obvious that one of their principal uses is to help remove suspended solids or impurities, particularly those that tend toward sedimentation. Secondarily then, it is also obvious that is blowing down, a portion of the boiler water is discharged thereby reducing the water level in the boiler. This function therefore aids as a safety measure, in avoiding carryover of water from the main steam drum in the event of high boiler water-level for whatever reason. A third use of these valves, but far less frequent, is the introduction of boiler cleaning acid to the boiler, and again draining of this acid after the boiler is acid-washed. Many boiler operators choose to pump this fluid through the blow-off valves, since they usually are a handy means of ready access to the boiler.In the case of a car, the "blow cock", aka blowoff valve(BOV) or dump valve is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blowoff valves relieve the damaging effects of compressor "surge loading" by allowing the compressed air to vent to atmosphere, making a distinct hissing sound, or recirculated into the intake upstream of the compressor inlet.
