Perkenalan

Waste heat boilers are a great way for companies to improve their energy efficiency and reduce the cost of heating and cooling. They can be used to recover waste heat from industrial processes and convert it into steam that can be used to heat systems. Waste heat boilers can be used in several different industries including chemical, petroleum chemical, oil and gas, food, Dan beverage industries. Dalam artikel ini, you will learn all about it. So that you can make the best choice.

Why waste heat boilers are used?

Reduce energy consumption. Waste heat boilers reduce the amount of energy that you use to heat your building and water by capturing the residual heat from industrial processes and transferring it to your facility.

Reduce greenhouse gases. Waste heat boilers can help you achieve LEED certification, as well as meet EPA requirements for reducing emissions into the atmosphere by capturing carbon dioxide (CO2) and other harmful pollutants created by burning fossil fuels such as coal or natural gas to produce electricity.

Increase efficiency by using less fuel overall. When used in conjunction with an existing boiler system, a waste heat recovery system will increase efficiency and reduce operating costs because it reduces demand for fuel purchases while also improving overall performance at lower temperatures than traditional furnaces alone could provide on their own.

What is a waste heat boiler?

A waste heat boiler uses the exhaust heat from a process to generate steam, which is used in a steam turbine to generate electricity. Keuntungan dari jenis sistem ini dibandingkan jenis pembangkit listrik lainnya adalah tidak memerlukannya konsumsi bahan bakar tambahan atau emisi CO2 dari pembakaran bahan bakar fosil.

Selain itu, karena boiler limbah panas sering digunakan sebagai bagian dari proses industri yang ada (seperti produksi baja), mereka dapat dipasang tanpa biaya modal yang signifikan atau perubahan dalam proses manufaktur itu sendiri.

Apakah boiler panas limbah penukar panas?

Boiler limbah panas adalah penukar panas. Penukar panas mentransfer panas dari satu media ke media lainnya. Pada kasus ini, sumber suhu rendah biasanya air yang telah dipanaskan oleh proses industri seperti pembangkit listrik atau manufaktur kimia. Sumber suhu tinggi dapat berupa uap yang dihasilkan dalam proses lain, atau bahkan limbah gas hasil pembakaran bahan bakar seperti batu bara atau gas alam. Boiler Pemulihan Panas Limbah (WHRB) digunakan untuk memulihkan energi yang terbuang sia-sia ini dan mengubahnya menjadi uap yang dapat digunakan untuk tujuan pemanasan.

Bagaimana cara kerja boiler limbah panas?

Boiler limbah panas adalah sistem tertutup, yang berarti menggunakan air sebagai fluida kerja dan pendinginnya. Air melewati tabung di dalam ketel dan menyerap panas dari gas pembakaran atau aliran pembuangan sebelum didinginkan kembali oleh udara segar yang ditarik masuk melalui kisi-kisi atau bukaan di kedua ujung setiap bundel tabung (disebut header).

Prosesnya dimulai saat Anda menyalakan mesin industri seperti tungku listrik atau mesin pembakaran. Which amounts of excess heat that isn’t required by its main purpose (for example: generating electricity). The waste heat is then transferred via pipes to the boiler where it is used to warm up water. Until it boils into steam at high pressure before being released into the atmosphere through a pipe.

What is the capacity of waste heat boilers?

The capacity of a waste heat boiler is measured in kilowatts (KW). This is the amount of electricity it can produce at any given time. The capacity depends on three factors:

• The efficiency of your heat recovery system, which affects how much waste heat you can use before you start losing efficiency or having to add more water to cool it down.
• The temperature of your source of waste heat, as well as its flow rate (how much air is flowing through it).
• Your needs for electricity, if you only need enough energy for one room’s worth of lights and appliances, then your requirements will be different than someone who needs power for an entire house or building!

What is the efficiency of a waste heat boiler?

A waste heat boiler is not 100% efficient. In fact, it’s usually around 70% ke 80%. It’s calculated as the ratio of energy output to input, and it’s usually expressed as a percentage. Misalnya, if your waste heat boiler converts 80 percent of its fuel into useful heat, then its efficiency rating would be 0.8 (atau 80%).

So if you have 1 kWh listrik yang keluar dari generator Anda yang digunakan untuk menghasilkan uap untuk proses Anda, Kemudian 0.7 – 0.8 kWh akan hilang sebagai limbah panas melalui berbagai proses dalam sistem.

Kehilangan ini terjadi karena gesekan pada pipa dan katup serta kehilangan panas pada koil dan komponen lain yang membentuk sistem itu sendiri. (seperti pompa).

Apa saja komponen boiler limbah panas?

Komponen utama boiler limbah panas adalah:

Penukar panas primer. This is the part of the boiler that transfers heat from one fluid to another. It’s usually made of copper or stainless steel, with a finned tube design to maximize efficiency.

Water treatment system. A water treatment system helps remove impurities from your water before it goes into your boiler so that it doesn’t clog up pumps or damage other components. There are many different types of treatment systems available depending on what kind of impurities are present in your supply source.

Control system. Waste heat boilers require constant monitoring. They need sensors and software so that you can control temperature levels throughout the operation. As well as detect if there are any problems occurring within the system itself (like leaks).

Boiler feed pump. The boiler feed pump is responsible for pumping water from the hot well, into your heating system. It’s an important component. Because it transfers heat energy to your home or building, which allows you to use less energy on heating costs!

Boiler feed tank. This component holds water at high temperatures so that it can be used by your heating system when needed.

What are the advantages and disadvantages of waste heat boilers?

Advantages of waste heat boilers

Save Energy

Save money on your heating bill by using the wasted energy from other processes in your plant or office building.

Environmental Protection

Reduce emissions because they don’t require burning fossil fuels or producing electricity for heat production.

Running Low Cost

These are less expensive to operate than traditional boilers. Because there is no need for fuel delivery or maintenance costs. Such as filters and pumps associated with traditional boilers that use fossil fuels like natural gas atau propane gas (LPG).

Disadvantages of waste heat boilers

Installation Cost Expensive

This is because of the complex nature of waste heat boilers and the expertise required for installation. The installation costs may also vary depending on where you’re located as well as whether you choose an electric or gas-fired boiler system.

More Maintenance

They require a lot of maintenance because they work at high temperatures and generate a lot of heat. This can lead to corrosion if not properly maintained. If your boiler is not properly maintained it could result in poor performance. Even failure causes downtime for your plant/business. This can be very costly especially if no alternative source exists nearby that would allow operations to continue without interruption.

How do I choose a waste heat boiler?

Choosing a waste heat boiler is an important decision. Here are some things to consider:

• The size of the boiler. A large, high-capacity boiler will be more efficient and cost-effective than a small one. But it may not fit your space requirements or budget constraints.
• The heat source used to generate steam (MISALNYA., electricity vs natural gas). If you’re looking for an environmentally friendly option that requires no additional fuel costs. Consider solar thermal panels as an alternative energy source for heating water before using them in your waste heat recovery system!
• Installation costs and maintenance requirements (think about whether you’ll need professional help with installation). If installing yourself isn’t something that sounds fun right now but would rather save money on someone else doing this part for you!

How much does a waste heat boiler cost?

The cost of an waste heat boiler depends on a number of factors including the size, efisiensi, and type of HRSG you choose. Smaller units can be purchased for as little as $5,000, while larger ones can cost over $100,000.

A waste heat recovery system is an investment worth making because it allows users to reduce their utility bills by up to 90%. In addition, sistem ini ramah lingkungan karena kemampuannya tidak hanya untuk memulihkan panas. Tetapi juga untuk mendaur ulang bahan yang tidak dapat digunakan menjadi sumber energi yang dapat digunakan seperti air panas atau uap.
