Hey there! I’m a supplier of sintered refractory products, and today I wanna chat about the applications of sintered refractory in the power generation industry. Sintered Refractory

First off, let’s understand what sintered refractory is. Sintered refractory materials are made by heating a mixture of raw materials at high temperatures until they fuse together. This process gives them excellent heat – resistance, mechanical strength, and chemical stability. These properties make them super useful in the power generation sector.
1. Coal – fired power plants
Coal – fired power plants are a major part of the power generation industry, especially in many developing countries. Sintered refractory plays a crucial role here.
Boiler linings
The boiler is the heart of a coal – fired power plant. It operates at extremely high temperatures, often reaching over 1000°C. Sintered refractory bricks are used to line the boiler walls. These bricks can withstand the intense heat and the corrosive environment created by the combustion of coal. For example, alumina – based sintered refractories are commonly used because they have high melting points and good thermal shock resistance. They prevent the heat from escaping the boiler, which improves the efficiency of the power generation process. If the refractory lining fails, it can lead to heat loss, reduced efficiency, and even safety hazards.
Furnace chambers
In the furnace chambers where coal is burned, sintered refractory materials are used to build the structure. The high – temperature environment in the furnace can cause wear and tear on the materials. Sintered refractories can resist the abrasion caused by the movement of coal particles and the high – velocity hot gases. They also protect the steel structure of the furnace from the high temperatures, preventing it from deforming or melting.
Ash handling systems
Coal combustion produces a large amount of ash. The ash handling systems, such as ash hoppers and chutes, are also lined with sintered refractory. The ash can be very abrasive and corrosive, and the sintered refractory lining helps to protect these components from damage. It ensures the smooth flow of ash and reduces the maintenance requirements of the ash handling system.
2. Gas – fired power plants
Gas – fired power plants are becoming more popular due to their relatively lower emissions compared to coal – fired plants. Sintered refractory also has important applications in these plants.
Combustion chambers
In gas – fired power plants, the combustion chambers operate at high temperatures. Sintered refractory materials are used to line these chambers. They can withstand the high – temperature flames and the chemical reactions that occur during the combustion of natural gas. For instance, magnesia – based sintered refractories are often used because they have good resistance to basic slags and high – temperature corrosion.
Heat exchangers
Heat exchangers are used to transfer heat from the hot combustion gases to water or steam. Sintered refractory can be used to protect the heat exchanger tubes from the high – temperature gases. It helps to improve the heat transfer efficiency and extends the lifespan of the heat exchanger.
3. Nuclear power plants
Nuclear power plants are another important part of the power generation industry. Sintered refractory has some unique applications here.
Reactor cores
Although the main components of the reactor core are made of specialized nuclear – grade materials, sintered refractory is used in some auxiliary parts. For example, in the shielding structures around the reactor core, sintered refractory can help to absorb and dissipate heat. It also provides some protection against radiation. The high – temperature stability of sintered refractory makes it suitable for use in the high – energy environment of a nuclear power plant.
Containment buildings
The containment buildings in nuclear power plants are designed to prevent the release of radioactive materials in case of an accident. Sintered refractory can be used in the lining of these buildings. It can withstand the high temperatures and pressures that may occur during an accident, providing an additional layer of protection.
4. Geothermal power plants
Geothermal power plants use the heat from the Earth’s interior to generate electricity. Sintered refractory has applications in these plants as well.
Geothermal wells
The geothermal wells are used to extract hot water or steam from the underground. Sintered refractory can be used to line the wellbore. The high – temperature and high – pressure environment in the geothermal wells can cause corrosion and wear on the wellbore materials. Sintered refractory can resist these effects and ensure the long – term stability of the well.
Heat recovery systems
In geothermal power plants, heat recovery systems are used to transfer the heat from the geothermal fluid to a working fluid. Sintered refractory can be used in the heat exchangers and other components of these systems. It helps to improve the heat transfer efficiency and reduces the energy losses.
