Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300 C. Inert kiln exhaust gases with oxygen content of about 3-5 are most suitable for the intended purpose due to high risk of fireexplosion in fine coal.
Pulverizer application for high volatile high moisture ,Figure 4 compares a conventional vertical table type pulverizer with a ball tube mill pulverizing system with crusher dryer. The table type pulverizer allows high temperature air to reach the coal charge. The ball mill system with crusher dryer normally reduces the inlet temperature to less than the auto ignition point of the coal charge.

Feb 27, 2018 Design air to fuel ratios AirCoal at high mill loading are in the 1.6 to 1.8 LbLb, KgKg range, with some designs in the 2.0 range for high moisture sub bituminous coals.
A method for drying coal in a coal mill and pneumatically conveying it to a kiln for burning, with a portion of the coal-dust-laden air generated thereby being diverted to a clinker cooler adjacent the kiln in order to ignite the suspended particles and supply hot air for burning the coal. The diverted air is later recirculated back to the coal mill to help dry the coal.
Jun 10, 2021 These components contain a lot of ash up to 5060 and moisture up to 2030. Coal waste and low-rank coals 3 are considered to be a high-ballast fuel as compared with clean coal due to the high content of water and mineral particles. On average, about 6070 of coal 9095 of coking coal is processed.
E.g. a high moisture content in the coal can result in a decreased maximum load gradient of the plant. In this paper a method for estimating the moisture content of the coal is proposed based on a simple dynamic energy model of a coal mill, which pulverizes and dries the coal before it is burned in the boiler.
Jun 07, 2018 Higher moisture content requires temperature extremes inside the mill. High moisture, high volatile matter and highly reactive coals are prone to self heating and can spontaneously ignite due to rewetting. Rehydration is exothermic and dried coal that is stagnate anywhere in the coal mill can begin to smolder and burn. Smoldering coal inside an ...
