Read More14/6/2018 · Considerable reduction in boiler size is possible due to high heat transfer rate over a small heat transfer area immersed in the bed. Low combustion temperature of the order of 750°C – 900°C facilities burning of coal with low ash fusion temperature, prevents NOx formation, reduces high temperature corrosion and erosion, and minimizes accumulation of harmful deposits due to low

Read More11 Losses due to heat transfer (radiation) to the environment The main form of heat transfer from boiler to boiler room is radiation. It is proportional to the outer surface area of the boiler and is usually 200-300 W/(m2K) for a well-insulated boiler having its outer surface temperature below 55 °C.
