Fire and Explosion Prevention in Coal Pulverizing Systems

In general, for a given system with coal dust dispersed in air throughout its volume (refer to Figure 1, Time = 0), the ignition source ignites adjacent suspended coal dust. Energy transfer from the burning coal to the next increment of unburned dust is by ordinary heat transfer, and if sufficient, will ignite the unburned dust.

However, larger wavelengths in the infra-red range (thermal radiation) are greatly distorted by the atmosphere except for two 'windows' around 4.3 microns and 8 to 14 microns. Through these windows it is possible to perceive variations in thermal radiation, both day and night and through haze and smoke.

Coil Pulverizers for Boilers

13/08/2009Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh (0.075 mm) and 99 % will pass through 50 mesh (0.300 mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty.

The Role of Coal Characteristics in Boiler Operation

For pulverized coal firing, the Riley Stoker Cor- poration makes the very simple and conservative assumption that all the ash in the coal is delivered to the electrostatic precipitator. In actual practice, probably 20% of the ash is caught in the boiler fur- nace hopper, so we have built in to the precipitator a 25% margin.

The elemental sulfur [ 28] in the coal enters the sulfide flame in the form of sulfur vapor when heated: S S = S 7 + S (11) S + O 2 = SO + O (12) S S + O = SO + S 6 + S (13) The following reactions occur when SO encounters oxygen: SO + O 2 = SO 2 + O (14) SO + O = SO 2 (15) 2.2.2. Model Simplification and Simulation of Coal

Pulverized coal storage in Bunker and coal handing system

The powdered coal is picked up by the air and the coal air mixture enters the classifiers, where sharp changes in the direction of the mixture throw out the oversized coal particles. The over-sized particles are returned to the drum. The coal air mixture from the classifier moves to the exhauster fan and then it is supplied to the burners.

Pulverized Coal

In general, CO emissions from pulverized coal-fired power boilers are low (50–200 ppmv) as the combustion system tends to be operated with sufficient excess air to maximize combustion efficiency [ 30 ]. Local standards, rather than national standards, are generally established to limit CO emissions and can vary widely.

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal

The coal from live storage is first crushed in small particles and then taken into pulverizer to make it in powdered form. Fine powdered coal undergoes complete combustion, and thus pulverized coal improves efficiency of the boiler. The ash produced after the combustion of coal is taken out of the boiler furnace and then properly disposed.
