If the superheater safety valve lifts first the excess pressure will be relieved and no damage will be done due to overheating. This is a good thing and the way it should work. If the boiler safety valve were to open first there would not be enough of a steam flow through the superheater to "cool" the tubes of the superheater which could result in severe damage. +++ ??? That does not read right at all. For a start, steam only flows through the superheater when the engine cylinder or turbine is operating. Locomotive boilers' superheaters don't have safety-valves on them, and the regulator is upstream of the superheater, but they don't overheat when the regulator is closed. The boiler safety-valve would not lessen the flow of steam through the superheater anyway - its role is to vent excess steam hence prevent over-pressure in the boiler. A safety-valve on a superheater would similarly only protect the pipes from over-pressure, not from overheating.In fact it's difficult to think of a situation in which a superheater can be overheated to the point of damage.
OK Let us look at your rebuttal to my answer and I will explain why you are wrong. First you say that steam only flows through the superheater when the engine cylinder or turbine is operating. This is true but it is the first indication that you don't really understand thermodynamics. The steam is not flowing but the temperature continues to rise. Just because the safety valve lifts you don't automatically shut off the fire and this heat continues to act on the superheater raising the temperature to a level where it could damage the metal of the superheater tubes. In other words, the superheater tubes get hot from the fire and the steam gets superheated by carrying this heat away. If this heat is not removed the tube overheats and becomes damaged.
But hey don't take my word for it lets see what the experts have to say. In the 40th edition of Steam, Its Generation and Use by Babcock & Wilcox Chapter 23 Page 6 under Safety and relief Valves paragraph 6 and I quote "For drum boilers with superheaters, Babcock & Wilcox (B&W) prefers to follow the Code allowed procedure of setting the safety valves so that the superheater valve(s) lift first at all loads, thereby maintaining a flow of steam through the superheater(s) to provide a measure of over-heat protection."

What is the first thing to observe when you are to operate a boiler?
The first thing to observe when operating a boiler is to ensure that all safety precautions are in place, including checking safety valves, pressure gauges, and water levels. Additionally, inspect for any leaks or unusual sounds that could indicate potential issues. Confirm that all control systems are functioning properly and that the area around the boiler is clear of obstructions. Finally, review the operating manual for specific guidelines related to the boiler type being used.
How do you refurbish a boiler?
Refurbishing a boiler involves several key steps: first, ensure safety by disconnecting power and water supplies. Next, disassemble the boiler to clean and inspect components such as the heat exchanger, burners, and controls for wear or damage. Replace any faulty parts, clean internal surfaces, and reassemble the unit. Finally, test the boiler for proper function and efficiency before returning it to service.
When was the first boiler invented?
1800
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.
Who invented a steam boiler furnace?
Inventor Granville Woods received his first patent on January 3, 1884 for a steam boiler furnace.
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.
How do you hot wire a peerless boiler to a generator?
Hot wiring a Peerless boiler to a generator involves connecting the generator's output to the boiler's power input. First, ensure the generator is off and the boiler's electrical supply is disconnected. Then, use appropriate gauge wires to connect the generator's output terminals to the boiler's power lines, ensuring proper polarity. Finally, start the generator and monitor the boiler for normal operation, while ensuring all safety protocols are followed. It's crucial to consult the boiler's manual and adhere to local codes for safety.

What is the first thing a boiler operator must do when taking over a shift?
The first thing a boiler operator must do when taking over a shift is to conduct a thorough walkthrough of the boiler room and associated equipment. This includes checking the status of gauges, valves, and safety systems, as well as reviewing any shift logs or notes from the previous operator. Ensuring that all systems are functioning properly and that there are no safety concerns is crucial before taking full control of operations. Additionally, the operator should familiarize themselves with any ongoing issues or special instructions relevant to the shift.
