Boiler Smoke system
The fuel burning at the furnace through, the exhaust gas flow from the boiler barrel bottom to the smoke window outlet on the Eight character wall, then enter convection bank at the both wings, next enter the thread smoke tube through the front smoke box, pass by economizer, dust remover, and induced draft fan, finally discharged to the atmosphere by chimney.
Functions of boiler various valve & guage
There are number of parts which are attached to boilers for their safe and proper working. They are as follows,
1. Water Level indicators.
Water level indicator is a safety component use to indicate the level of water inside the boiler to an observer. It is an essential component needed for the proper and safe functions of boiler and it is mounted on the front side of boiler.
2. Pressure Gauge.
Pressure gauges are uses to show the pressure, which builds up inside the boiler due to steam. They re usually installed in front side of boilers and spring type pressure gauges are the most common type of gauge used to measure the pressure.
3. Safety valve.
Safety valves are essential to protect boiler from explosion due to very high pressure of steam inside the boiler. They are installed at steam chest. Its function is to blow off the pressure when it exceed the safety level.
4. Steam stop valve.
Steam stop valve in used to control the flow of steam from boiler to the main steam pipe and shut down the steam supply when required. It is installed the highest point of boiler with the help of a flange.
5. Blow down valve.
Function of blow off cock is to empty the boiler when required and it also help in removing mud and scales from the bottom of the boiler.
