What is the function of a boiler onboard the ship?

Boilers are one of the essensial equipments onboard ships. It’s purpose is to provide heating to the the main deisel propulsion engine, to the bunker F.O. tanks(to make it less viscous for transfer purposes as well as easy ignition).

What is the function of boiler?

Boilers are used to produce steam. The generation part of a steam system uses a boiler to add energy to a feedwater supply to generate steam. The energy is released from the combustion of fossil fuels or from process waste heat.

What is a boiler and state its importance on board?

A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.

What is the primarily function of steam boiler onboard the ship nowadays?

Today, the steam generated by the boiler is utilized in various systems in the engine room, including heating of fuel for the main engine.

Which boiler is used in ship?

Generally on ships, we use internally fired boilers, but in earlier times we used to make steam with the help of coal. High pressure or low pressure- Tankers ships uses the high pressure boilers. Natural or forced circulation of water- Ship normally uses the forced circulation of water.

What are the main parts of a boiler?

What are the Main Components of a Commercial Boiler

• Burner. The burner is the part of the boiler where air mixes with the fuel source and combusts.
• Combustion Chamber.
• Heat Exchanger.
• Controls.
• Supply Lines and Return Lines.
• Circulator Pump.
• Exhaust Stack.
• Conclusion.

What is the most important part of a boiler?

heat exchanger

What are two parts of a boiler?

The boiler is the part of the system that heats the water to be distributed. The key elements of a boiler include the burner, combustion chamber, heat exchanger, exhaust stack, and controls. Boiler accessories including the flue gas economizer are also commonly used as an effective method to recover heat from a boiler.

How does a boiler operate?

Your boiler powers on and uses either oil, gas or electricity to create heat. The heat from the fuel source is used to heat up water inside the boiler. The heated water or steam is sent throughout your home (via radiators or radiant floor systems) where it gives off its heat to warm the air.

What is boiler pressure?

Boiler pressure refers to the pressure of hot water running in your sealed central heating system, while water pressure is the pressure of the water coming through your taps. Primarily, if you have low boiler pressure your system could cut out, preventing your central heating from working.

What is inside the boiler?

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 a pipe carrying cold water.

What is boiler capacity?

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg – hf) m (1)

Can a boiler explode?

Boilers can certainly explode. This is usually due to a build-up of pressure or mechanical failure due to the boiler deteriorating. Technology has significantly decreased the frequency of boiler explosions, making them a safer way to heat your home.

Which boiler is more efficient?

Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. A condensing boiler has a larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.

How do I calculate boiler capacity?

Boiler Capacity – Engineering ToolBoxA boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg – hf) m (1).

Why is boiler efficiency important?

The Importance of Boiler Efficiency To put it simply, the more efficient that your boiler is, the less you will spend on fuel. By calculating boiler efficiency, you are able to forecast the fuel costs, in which you can, ultimately, determine the full life cycle cost of the boiler.

What are the factors that affect boiler operation?

5 Factors Killing Your Industrial Boiler Efficiency & What to Do…

• Excess Air Effect on Industrial Boiler Efficiency. All combustion burners require some degree of excess air.
• Flue Gas Temperature.
• Convection and Radiation Losses.
• Fuel Specification.
• Ambient Temperature.

How can I improve my boiler performance?
