How Power Plant Boiler Works? How Combustion System in

Working Of A Power Plant Boiler. Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures. This series explains the working of the boiler in modern power plant.: JohnzactrubaCoal Combustion Systems: Coal-fired Plants Reduce NO x https://Secondary air is injected into the boiler through coal burners on levels 2, 4 and 6, oil burners at levels 3 and 5 and through the auxiliary air ports on levels 1 and 7.

How to Run a Coal Fired Boiler at the Best Efficiency

Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.
