What is meant by marcet boiler?
the apparatus ( Marcet Boiler ) consist a cylinder surrounded with isolated substance in it electrically heated boiler which is used to heat up water and to measure the both of the temperature and pressure, & it contains thermometer & barometer & safety valve .
What is turn down ratio of a boiler?
the effective range in which it can be used; ie the temperature ranges of operation
What are the types of boiler tube failure?
due film boiling ,metal temperature riser tubes increase cases for rapture.
How do you understand whether circulating pump is circulating water through economizer?
By measuring outlet temperature of water at downstream of pump and upstream of boiler.
What is Ik pass in a boiler?
An IK on a boiler is a Soot Blow. It is mounted on the sidewall of a boiler furnace and cleans the internal boiler parts with high pressure.
How do you measure temperature of boiler in sugar factory?
measurement of temperature of boiler in suger factory
What is the use of economiser in boiler?
The economizer is used to raise feedwater temperature up to nearly the temperature of the boiler to avoid thermal shock and improve the boiler's efficiency. Every 11 degrees Fahrenheit increase in feedwater temperature yields a 1% increase in boiler efficiency.
Why boiler is operated close to critical temperature?
Greatest efficiency at that temperature.
What can happen if you had a sudden drop on boiler steam pressure without a corresponding drop in boiler water temperature?
BOILER EXPLOSION- Caused by a sudden drop in pressure (failure on the steam side) without acorresponding drop in temperature.
What is the temperature of boiler in sugar factory?
400 DEGREE
In order for a high temperature boiler or steam engine to produce superheated steam?
In order for a high temperature boiler or steam engine to produce superheated water, or steam?
Why economiser is used in boiler?
An economizer is used to heat boiler feedwater up closer to the temperature of the boiler water, using heat from the boiler exhaust gases, heat that would otherwise be wasted. The main reason is to improve the efficiency of the boiler. For every 44 degree F drop in exhaust gas temp. there is an 11 F rise in feedwater temperature and a 1% gain in boiler efficiency.
Can termosat on boiler fail?
Of course it can fail. Look at the temperature of the water in the boiler, turn the stat up and down. You should hear a slight click when the temperature setting and the boiler water temp are appx the same if you do, the stat is probably good. You can verify this with a voltmeter.
What will be the effect of lower water level in boiler?
Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.
What part of the body serves as a boiler?
The hypothalamus controls the body's temperature.
How a hot water boiler works?
It heats water to a desired temperature
How do you control steam temperature in a boiler other then spray in supreheater and reheater?
Pressure /temperature relationship The greater the pressure normally the higher the temperature
