Boiler Automation

  1. What are boiler and its function?

Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam. Steam produced in a boiler can be used for a variety of purposes including space heating, sterilization, drying, humidification and power generation.

  • What are the types of boilers?

There are two general types of boilers: ”fire-tube” and ”water-tube”. Boilers are classified as

  • “High-pressure” or
  • “Low-pressure” and
  • “Steam boiler” or
  • “Hot water boiler.”
  • What are boilers used for in industry?

Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines. Boilers are used to for a many purposes. They can provide hot water to heat buildings or very high pressure boilers can provide steam to drive electric generators or turbines to propel ships at sea.

  • What are the main parts of a boiler?

Although designs vary, a boiler has four main parts: the burner, the combustion chamber, the heat exchanger and the pluming apparatus.

  • Burner. The burner initiates the combustion reaction within the boiler
  • Combustion Chamber
  • Heat Exchanger
  • Fuel Sources

Other Uses of the Design

  • Maintenance
  • Warning.
  • How do industrial steam boilers work?

Industrial steam boiler is mainly applied to supply heat and steam to meet the industrial production meet. An industrial steam boiler is a vessel that contains water and a heat source powered by oil, gas, coal or biomass. There are two main types of boilers according to the structure: fire tubes and water tubes.

  • What is a PCB board in a boiler?

PCB is short for Printed Circuit Board. Modern boilers are controlled electronically and the PCB is the ‘brain’ of the boiler.

  • How do boilers work?

The boiler is the most important part of a central heating system. A valve opens, gas enters a sealed combustion chamber in the boiler through lots of small jets, and an electric ignition system sets them alight. The gas jets play onto a heat exchanger connected to pipe carrying cold water.

  • Are boilers safe?

Faulty boilers are usually safe. A dangerous boiler can kill. However, In many cases, a faulty boiler may just need reset. Most modern, room-sealed boilers have safety precautions such as thermostats; overheat stats, pressure relief valves and oxygen depletion sensors already fitted.

  • What causes a boiler to crack?

Stress corrosion cracking at the lap joints was a common cause of early boiler explosions, probably caused by caustic embrittlement. The other common cause of explosions was internal corrosion which weakened the boiler barrel so that it could not withstand normal operating pressure.

  1. Is a leaking boiler an emergency?

If a gas boiler is leaking, you should not attempt to repair it yourself; gas boiler repairs should only ever be conducted by Gas Safe Registered engineers. A leaking boiler is actually quite a serious problem, and indicates that an internal component such as a seal or valve is broken.

  1. How do you know if your boiler is leaking carbon monoxide?

Look for stains, soot or discoloration on (or around) your boiler, fire or water heater.

  • Make sure there are no blockages in your chimney or flue.
  • Check the pilot light on your boiler 
  • And any other gas flames that normally burn blue. If the flame is yellow or orange, you might have a carbon monoxide leak.
  1. Can a boiler explode?

A constant flow of gas into the boiler will also cause the temperature and pressure to increase rapidly, which can lead to a runaway boiler. Even if the boiler does not explode, its internal components may still melt, creating toxic smoke and vapor that can prove fatal.

  1. What causes a boiler to leak?

A leaking boiler is actually quite a serious problem, and indicates that an internal component such as a seal or valve is broken. The leak can lead to corrosion and rust, or can cause electric components within the boiler to short circuit. It could even cause problems throughout your house, including structural damage.

  1. Can a boiler cause a fire?

A faulty boiler, or one that has a blocked or leaky flue, can release a poisonous gas called carbon monoxide (CO). As well as the dangers of carbon monoxide (CO), a gas leak from your central heating can cause a fire or explosion. This can result in catastrophic consequences.

  1. Why would a boiler explode?

There are many causes for boiler explosions such as poor water treatment causing scaling and overheating of the plates, low water level, a stuck safety valve, or even a furnace explosion that in turn, if severe enough, can cause a boiler explosion.

  1. 4 signs your boiler could be dangerous

The signs below are dangerous and mean your boiler should be switched off IMMEDIATELY.

  1. The smell of spent gas or fumes
  2. Any visible signs of scorching, scooting or black spillage marks (also applies to room-sealed appliances)
  3. The pilot light continually going out or a yellow flame
  4. The frequent feeling of headaches or nausea when the boiler is running
