A Coal-fired water tube boiler is a type of boiler that uses coal as its fuel source. It is a water tube boiler, which means that the water is heated inside the tubes and the hot gases pass around them. The heat from the hot gases is transferred to the water, which then circulates through the boiler to produce steam. The steam is used to power turbines, which generate electricity.

A condensing Coal-fired water tube boiler works by using a heat exchanger to extract heat from the flue gases. The heat exchanger is made up of a series of tubes that are surrounded by water. As the flue gases pass through the tubes, the heat is transferred to the water, which then circulates through the boiler to produce steam.The condensing Coal-fired water tube boiler is designed to be highly efficient, with an efficiency rating of up to 98%. This is achieved by using a secondary heat exchanger to extract additional heat from the flue gases. The secondary heat exchanger is made up of a series of fins that are attached to the tubes. As the flue gases pass over the fins, the heat is transferred to the water, which then circulates through the boiler to produce steam.
Advantages:Coal-fired water tube boilers are highly efficient, with an efficiency rating of up to 98%.They are capable of producing large amounts of steam, making them suitable for industrial applications.They are relatively easy to operate and maintain.They are cost-effective, as coal is a relatively cheap fuel source.Disadvantages:Coal-fired water tube boilers produce emissions, including carbon dioxide, sulfur dioxide, and nitrogen oxides, which can contribute to air pollution.They require a large amount of space, as they are typically larger than other types of boilers.They can be noisy, as the combustion process can be loud.They require regular maintenance to ensure they are operating efficiently.
Coal-fired water tube boilers are used in a variety of applications, including:Power generation: Coal-fired water tube boilers are used to generate electricity by producing steam to power turbines.Industrial processes: They are used in a variety of industrial processes, including food processing, chemical manufacturing, and paper production.Heating: They can be used to provide heat for buildings, such as hospitals and schools.
There are several types of Coal-fired water tube boilers, including:D-type boiler: This type of boiler has a single drum and a vertical tube configuration. It is commonly used in industrial applications.A-type boiler: This type of boiler has two drums and a horizontal tube configuration. It is commonly used in power generation applications.O-type boiler: This type of boiler has a single drum and a vertical tube configuration. It is commonly used in marine applications.
One example of a Coal-fired water tube boiler application is the Taishan Power Plant in China. The plant has four 1,000 MW ultra-supercritical Coal-fired water tube boilers, which are capable of producing a total of 4,000 MW of electricity. The boilers are highly efficient, with an efficiency rating of up to 98%. The plant is one of the largest Coal-fired power plants in the world and plays a significant role in meeting China’s energy needs.
