Coal Fired Boilers having Direct Tangential Firing System ...

In direct tangential firing systems, the pulverized coal from the coal mills is directly taken to the furnace. Coal properties such as FC/VM (Fixed Carbon / Volatile Matter), particle size, oxygen, calorific value of the coal, reactivity, and ash content seem to be the most important variables for pulverised coal combustion in tangentially fired boilers, and they are highly inter-related.

Technical Data - Atritor

An indirect firing system dissociates fuel prepara-tion from combustion and is often essential for a multi-burner or multi-combustor system. It introduces a bag filter in place of the cyclone of the semi-direct system, and silo storage of the ground product. This requires a full study of fire and explosion risks and the inclusion of appropriate safeguards. • Rotary kilns (cement and lime ...

Pulverised Coal Combustion with higher efficiency ...

Many conventional pulverised coal-fired power plants have been improved by upgrading the system so that emissions of several pollutants could be reduced, but the efficiency gains are minimal as the heat rates can only be improved at existing plants by 3 to 5%-points at best. This is because the heat rate is primarily dependent on unit design, specific fuel type, and capacity factor, and ...

Why Pulverized Coal is Used in a Power Plant

The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant. A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons ...

In pulverised fuel firing systems, the coal particles are carried along with the air and combustion gas flow. Because particles are entrained in the gas flow, this firing type is also known as entrained-flow combustion. Pulverised fuel and combustion air are injected into the firing via the burner and mixed in the furnace. With a fine raw coal milling degree and high combustion gas ...
