If the pressure in a steam boiler exceeds a set limit, a safety valve is provided that will open to relieve the pressure. This prevents a boiler explosion. When the pressure is being relieved in this way, very hot steam will be release from the valve. The hot steam is extremely dangerous to people, therefore a discharge is provided. This is a pipe or other means of directing the hot steam to a release point outside, away from where people are likely to be.

Raise the pressure in the boiler until the valve relieves and note the pressure at which it does so.


Difference between boiler mountings and accessories?

Boiler mountings are different fittings and devices which are necessary for the operation and safety of a boiler .e.g. pressure gauge, safety valves , steam stop valve etc Normally these device are mounted over boiler shell .Boiler Accessories are auxilary plants or parts required for steam boilers for their proper operation and to increase efficiency of the boiler .e.g.feed pumps, super heater , economiser etc


Why is to safety valve mounted on boiler drum?

the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.


What is the function of back pressure valve in Boiler feed pump?

The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.


Why the pressure release valve must be installed directly on the boiler with a few fittings as possible and with no valve in between the components and the boiler?

The pressure release valve must be installed directly on the boiler to ensure immediate activation in case of overpressure, providing a direct path for steam or water to escape. Minimizing fittings and avoiding valves in between reduces the risk of leaks and obstructions that could impede the valve's function. This direct installation also ensures compliance with safety regulations and optimal performance of the safety system. Any delay or resistance in the release path could lead to catastrophic failure of the boiler.

What is the purpose of a diverter valve in a boiler system and how does it function to regulate the flow of water or steam?

The purpose of a diverter valve in a boiler system is to control the direction of water or steam flow. It functions by diverting the flow of water or steam to different parts of the system, allowing for regulation of temperature and pressure. This helps maintain efficient operation and prevent damage to the boiler.

What is water inlet valve in boiler?

The water inlet valve in a boiler is a critical component that controls the flow of water into the boiler system. It regulates the supply of water needed for heating, ensuring that the boiler operates efficiently and maintains the desired pressure. When the boiler requires water, the valve opens, allowing water to enter, and it closes when the necessary level is reached. Proper functioning of the water inlet valve is essential for the overall performance and safety of the boiler.


Why is my boiler pressure relief valve dripping?

Your boiler pressure relief valve may be dripping due to high pressure in the system, a faulty valve, or a buildup of sediment or debris. It is important to have a professional inspect and repair the valve to prevent any potential safety hazards.
