Boiler is an essential part of a power plant, as it is used to generate steam for the generation of electricity. The process flow of boiler is a complex one and involves several steps such as preheating, combustion, heat transfer, water treatment and cooling. This article aims to provide an overview of the process flow of boiler in a power plant.

The preheating process is the first step of the boiler process flow. In this step, air is heated to a certain temperature before it is injected into the boiler. This helps to increase the efficiency of the boiler and reduce the amount of fuel required for combustion. After the preheating process, the air is injected into the boiler where it is mixed with fuel and burned to generate heat.

The heat generated in the combustion process is then transferred to the water in the boiler. This is done by passing the hot gases through the tubes in the boiler. As the water is heated, it turns into steam and is then collected in the steam drum. The steam drum is then used to control the pressure and temperature of the steam.

The next step in the process flow of boiler is water treatment. This step involves removing any impurities from the water to ensure that it is clean and safe for use. This is done through the use of various filters and chemicals. After the water is treated, it is then pumped into the boiler where it is heated to generate steam.

The final step in the process flow of boiler is cooling. This is done by passing the steam through a cooling tower or a condenser. This helps to reduce the temperature of the steam and make it safe for use. Once the steam is cooled, it is then used to generate electricity in the power plant.

Process flow of boiler is a complex process and requires a great deal of knowledge and expertise to ensure that it is done properly. It is important to ensure that all the steps are followed correctly to ensure that the boiler is operating efficiently and safely. It is also important to ensure that the water used in the boiler is clean and free from impurities, as this can affect the efficiency of the boiler.
