Coalfired power plants are characterized by high combustion temperature and wellequipped air pollution control devices. The trace organic pollutants in the municipal solid waste incineration (MSWI) flue gas would be completely destroyed if the MSWI flue gas was injected into the high temperature area of a coalfired boiler.

general process is called Oxidation ... Oxygen combines rapidly with certain types of fuels, such as coal, oil, gas or wood, and substantial amounts of heat are liberated. • The Degree of Flammability depends on how easy it is to turn into a gas, because nothinggy g p truly burns until it is a gas. This in turn depends on the nature and quantity of the substance, compared with .

Boiler: The mixture of pulverized coal and air (usually preheated air) is taken into boiler and then burnt in the combustion zone. On ignition of fuel a large fireball is formed at the center of the boiler and large amount of heat energy is radiated from it. The heat energy is utilized to convert the water into steam at high temperature and pressure. Steel tubes run along the boiler walls in ...

Certain coals tend to form slag and sintered deposits in the combustion chamber of the boiler. The slagging effects leads to a reduction in efficiency of the plant and eventually the plant needs to be shut down for cleaning in short intervals. In extreme cases, deposits on super heaters can grow to a size of several hundred kg and severely damage boiler tubes when falling down. .
