  • What is a Steam Boiler? Working, Types of Heat Transfers

    Apr 23, 2019 · Radiation does not require particles or a medium to transfer energy. Heat moves in three ways like radiation conduction and convection. In this part of the boiler the primary way that heat is transferred to the water is through convection convection involves blowing heat across something. Both of these processes are very important in numerous fields.Learn More
