Typical Causes of Slagging and Fouling Problems in Boilers

Jun 1, 2015 . Here are six of the most common causes of boiler slagging and fouling in our experience: □ Low furnace excess oxygen. □ Extreme stratifications of the FEGT flue gas lanes. □ High primary airflows. □ Burner damage and deficient mechanical condition/tolerances. □ Poor coal pulverizer performance.

Preliminary investigation on the effects of primary airflow to coal .

fineness in coal-fired boilers. In coal fired power plant, coal is pulverized in a pulverizer, and it is then transferred to boiler for combustion. Coal need to be ground to its desired size to obtain maximum combustion efficiency. Coarse coal particle size may lead to many performance problems such as formation of clinker.

Clinker Formation in Boilers.docx | Boiler | Coal - Scribd

Clinker Formation in Boilers of Thermal Power Plant. We must not blame poor quality coal for clinker formation and deposition in boilers. Instead we take proper precautions such as poking, flushing by providing more water in the hopper, soot blowing by injecting steam to remove soot deposits on water wall, and making our.

What are reasons for clinkers being formed in coal based boiler .

reference: Avoiding Clinker Formation in Thermal Power Plant Boilers Clinker or slag is a fused mass of non-combustible residue (ash) from coal. All coal has some amount of ash content; bad coal has more ash, that's all. Oxidation of the minerals .

Slag Control Treatment Program at EKPC Spurlock Station

Illinois Basin coal is high sulfur, low fusion tempera- ture coal. Burning some Illinois Basin coals would create a buildup of hard slag formation inside the boil- er. Typical issues included the formation of large clinkers on SH assemblies. Spurlock Station has expe- rienced large slag falls causing boiler damage and.

Report of the Group for Studying Range of Blending of Imported .

Apr 19, 2011 . As per observations, even with imported coal firing in 4 mills (A,. B, C, D) and indigenous coal in one mill (E), no slagging / deposits or clinker formation was observed in the furnace. However, both the indigenous coal and the imported coal had very high moisture content of about 30% due to rainy season.

Impact of Blended Coal Firing on the Power Plant Performance

Ash Fusion Temperature. (Clinker formation in the boiler). □ Studies on the blending of UK power grade coals indicates that the blend has shown more slagging propensity than componet coals. 1:10 (Slagging:Non-slagging). □ Reason is the excess presence of iron content from the slagging coal.

Coal Bottom Ash/Boiler Slag - Material Description - User Guidelines .

When pulverized coal is burned in a dry, bottom boiler, about 80 percent of the unburned material or ash is entrained in the flue gas and is captured and recovered as fly ash. . It is possible that EPA's study on mixed power plant wastes could have a regulatory impact on beneficial use or reuse of any mixed materials.

clinker formation coal mill,What Causes Clinkers in Coal Fired Boilers? | Hunker

Oct 19, 2011 . Coal clinkers form when noncombustible elements contained in coal such as iron, calcium, silicon, aluminum and sodium interact with sulfur and carbon at high temperatures. These elements melt together with clays and alkalis to form a glassy slag that eventually hardens into clinkers. Clinker formation is a.

3.4 - Burning in a kiln – clinker formation

A variety of fuels can be used, including pulverized coal or coke, natural gas, lignite, and fuel oil. . The nodules formed in the clinkering zone are now hard, and the resulting product is called cement clinker. . Once the nodules of cement clinker have cooled, they are ground back into a fine powder in a large grinding mill.
