Forced draft is a method used to enhance the airflow in various systems, such as boilers and furnaces. It involves using a fan or blower to push air into the combustion chamber, ensuring a consistent supply of oxygen. This process improves combustion efficiency and helps maintain optimal operating temperatures. In industrial applications, forced draft systems are crucial for maintaining performance and safety. By increasing the air pressure within the system, they help prevent the buildup of harmful gases and ensure complete fuel combustion. This technique is commonly used in power plants and large heating systems, contributing to energy efficiency and reduced emissions.
