Effect of Opposing Tangential Primary Air Jets on the Flue ...

An experimental and numerical study on the effect of opposing tangential primary air jets with different biased angles on aerodynamic fields in the furnace and the flue gas velocity deviation in the horizontal flue gas pass was carried out in a tangentially fired boiler model of a 600 MW unit. The results show that the flow fields in the left and right sides of the upper furnace are obviously ...

CFD Analysis of Temperature Imbalance in Full Scale ...

Tangentially fired boilers are widely used in generating electricity power due to its advantage of distributing heat evenly to all furnace walls. However this type of boiler poses common temperature deviation at the upper furnace which may lead to temperature imbalance. This consequently may reduce the performance of the boiler which cannot be simply ignored.

Simulation of an Industrial Tangentially Fired Boiler ...

At an integrated steel mill industrial boilers combust a variable mixture of metallurgical gases combined with additional fuels to generate high-pressure superheated steam. Most tangentially fired boilers have experienced water wall tube failures in the combustion zone which are thought to be caused by some deficiency in the combustion process. The challenge faced in this present process is that there are very limited means to observe the boiler

Why the quality of boiler feedwater is an important ...

Scaling inside a boiler occurs as the salts in the boiler water get deposited when the water that contained these salts is evaporated to produce steam. Depending on the amount of solids in the water or hardness the rate of scaling varies. If left unchecked scaling can also destroy a boiler. Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube
