Fireside corrosion in pc-fired boilers - ScienceDire

The furnace wall tubes experience the largest heat flux (200-500kW/m2) of all the boiler tubes due to the large temperature gradient between the hot gases in the combustion zone and the relatively cool waterwall tubes (350-400). The temperature gradient has an important influence on the corrosion behavior of the system.

Boiler (power generation) - Infogalactic: the planetar

2018-4-7 · A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water. The higher the furnace temperature, the faster the steam production.
