Jul 01, 2007 The coal mill uses the preheater exhaust gases, which have elevated amounts of SOsub 2. ... the operating temperatures were below the sulfuric and hydrochloric acid dew points. Because of this corrosive acid stream in the gas flow, the bag filter started corroding. ... This condensation occurs on surfaces that are at or below the dew point of ...
Coal mill is major equipment of cement plant and used for drying and grinding coal. Compared with rock grinder stone flour mill, the coal mill we make is with reasonable structure, high grinding efficiency and is the ideal equipment for coal processing. ... the temperature of the air from the coal mill is higher the dew point. Make an ...
The coal mill multi-scan analysis system includes SDFP and SDSP, sample lines and a gas conditioning system. ... The gas is then delivered to the analysers with a fixed reference of dew point, flow, pressure and temperature in order to establish correct analytical correlation with any data taken at any other time.

Coal Moisture The degree of drying, and therefore the required mill outlet temperature from 65-80 0 C will depend upon the type of coal ground. Some residual moisture in fine coal is recommended Graph below to minimize the potential of spontaneous ignition of fine coal, which will again vary for different coal types as below
Coal mill Common Issue Mill bag filter jamming. It happens due to high moisture content of coal, low air flow, higher dew point, lower mill outlet temperature, false air in circuit, weak insulation of bag filter and mill ducts, jamming of rotary extractor at hopper bottom or difficulty to

The plant has raw materials, which are high in pyritic sulfur. The coal mill uses the preheater exhaust gases, which have elevated amounts of SO sub 2 sub . The coal being used is highly volatile. Therefore the coal mill bag filter had few occurrences of smoldered bags causing potentially unsafe conditions. This problem was solved by implementing some operational changes like reducing the ...
Application of ESP is studied, keeping in view Indian conditions. The characterisation of dust emissions has been done for different units, such as rotary kiln and raw mill, alkali by-pass, clinker cooler, cement and coal mill, in terms of exit gas quantity, temperature, dew point, dust content and particle size.
Dew point in drying gas lowered by means of water vapor condensation in a spray cooler. Drying energy supply based on inert stove waste gas, complemen-tary on blast furnace gas combustion.

To summarize the coal mill controls, they may be divided basically into two major categories. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
