What is boiler corrosion?
the decay of boiler material by chemical or electrochemical attack by its environment is known as boiler corrosion
How do you prevent boiler explosion?
All boilers are made to a pressure specification and in most countries any pressure vessel over a certain size is required to be periodically inspected and pressure tested to ensure it is fit for purpose. In addition to being in sound condition, the boiler is also expected to have some form of pressure relief valve. This is of sufficient size to vent off excess pressure before it gets to an explosive situation. It is obviously important that the pressure of this device is set to a lower level than the ultimate pressure specification of the boiler. Even quite small boilers, like those in coffee makers need to be inspected. Some boilers are 'gas fired' such as home heating boilers. These have a device called a thermocouple that detects the flame and is linked to the gas valve. If the flame goes out, or the burner does not ignite when gas is released in the boiler, it will shut the gas off. Typically gas fired boilers have a number of devices that will shut off the gas in the event that something doesn't work. This means that if the gas supply pipe is in sound condition, the boiler itself cannot leak gas and cause an explosion.

What is the difference between the operation of a automatic boiler and manual boiler?
boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
How important is boiler cleaning and repair?
To comply with various laws, to ensure the boiler and its parts are operating at peak performance and therefore doing its job, to reduce dangers of emissions, explosion. To maintain low running costs and to meet the requirements of warranties

What is boiler feed water pump?

What safety measures should do by boiler tender during his watch?
The first and most important thing the operator must do at the start of his watch is to check the true water level in the boiler. This is done by first blowing down the water column, then blowing down the gage glass, remembering to close the gage cocks individually and reopening them to the proper position. Next he should check with the previous operator and check the log books for any known problems. Checking the safety valves, bottom blowing the boiler, testing chemistry of the water, checking safety cutoffs, and blowing soot off the tubes are all regular shift operations that must be done to maintain a safe operating condition of the boiler. Also, cleaning the boiler room is very important and shouldn't be overlooked, more operators are injured by slips and trips than any other hazard.
Why salinometer valve fitted in boiler?
its a device use for measuring the salinity of boiler water. it is generally fitted in water drums .its is provided to prevent the flashing off of boiler water under high pressure condition.
What does boiler blowdown means?
Boiler blowdown is required to prevent corrosion by removing impurities that contribute to its formation in a steam boiler and to facilitate the generation of pure steam by preventing the carryover of impurities. Why Boiler Blowdown is Required? Proper blowdown procedures are necessary to maintain the solids content of the boiler water within specific limits and to quickly eliminate contaminants if the water becomes contaminated.
What is silica level in boilers?
silica level changes according to boiler type sub or super critical boiler but its level should be less than 200ppm at rated condition
CFBC boiler operation procedure?

Why boiler is in vaccumed condition?
Because you forgot to open the vent when the pressure dropped below 15 psig. A boiler under vacuum will suck in its handholes and manholes, and they might start leaking when pressure is put back on them. weakened boiler parts can fail as well.
When does one change their steam boiler?
Some steam boilers can make it to 40 years. Always check the condition of the doors, brickwork, burners, and controls. If there is excessive rusting or leaks, the steam boiler needs to be replaced.
