3.1 This test method provides a means for assisting in the evaluation of pulverizers and pulverizer systems in terms of fineness specifications. It may also be used to confirm the influence of coal fineness on combustion performance and to evaluate carbon loss. By consent among interested parties, it may be used for evaluation of coal fineness in preparation, pneumatic transfer systems, etc.
Pulverizer - Wikipedia. With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher . 50 mesh and 80% or higher 200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of 100 mesh and 95% 200 mesh, or better..

Put the coal mill under the sound insulation cover assembled by steel structure.(2) the use of heat resistant lining control method. The coal mill cylinder body manganese steel lining is replaced with a certain elastic heat resistant lining, reduce the impact noise of the coal mill;(3) the use of closed sound insulation room method.
Pulverized firing burners are mounted on the furnace where the PF, PA, and SA come together to get properly mixed and enter combustion. Combustion of the pulverized coal particle starts with immediate flash drying of moisture and devolatilization due to the combination of intense radiation from the flame and convection from the hot gases.
Every coal pulverizer is designed with a particular fuel grinding capacity, or throughput, at a certain Hardgrove grindability index (HGI), based on moisture content, a defined raw coal size, and desired fineness level. These factors must all be considered and are significant in discussions of pulverizer .

For these reasons, FGR is not a cost effective means for NOX control on coal-fired boilers. 3.7 Pulverized Coal Fineness The fineness of coal pulverization has been noted as a variable which can affect NOX emissions, at least to a minor degree. Theoretically the coarser the coal, the longer it takes the coarser particles to burn out.
On the one hand, the use of high-quality raw coal (low water, less debris, etc.), from the contract agreed to grasp the source control while doing a good job of process cleaning, on the other hand grasp the fine operation control of the coal mill system, for the production of better quality The pulverized coal .
