The safety valve is primarily used to release excess pressure in a boiler to ensure safe operation. In the context of a boiler system, maintaining the correct pressure is critical for efficiency and safety. A safety valve is designed to automatically open when the pressure inside the boiler exceeds a predetermined level, allowing steam or water to escape and thereby reducing pressure to safer levels. This mechanism prevents the potential for dangerous situations, such as explosions or structural damage due to overpressure.

Other components like pumps, blowers, and heat exchangers serve different purposes in the boiler system. Pumps are mainly responsible for circulating water within the system, blowers are used to supply air for combustion, and heat exchangers facilitate the transfer of heat between fluids. While all these components play important roles in the overall functionality and efficiency of a boiler, it is the safety valve that directly addresses the critical need to manage and relieve excess pressure.
