What is a convection type super heater?

A convection type super heater is specifically designed to enhance heat transfer through the movement of fluids, primarily steam and hot gases, in a boiler system. The correct understanding of this super heater is that it is placed in the gas passage of the furnace. This positioning allows it to utilize the hot gases that flow through the system, thus efficiently converting steam into superheated steam by absorbing heat from these gases.

In this setup, the super heater relies on convection to transfer heat to the steam, making the process highly effective as the flow dynamics of the gases optimize the heat transfer rates. This system allows for better thermal efficiency within the boiler and aids in reaching the superheat temperatures necessary for efficient power generation.

The choices that suggest other locations or characteristics are misleading as they do not accurately represent the fundamental operation and design aimed at maximizing efficiency in the generation of superheated steam. For instance, while a convection super heater could potentially be placed between passes in certain configurations, its primary function hinges on being integrated within the gas passage for optimal performance.
