Clinker Minimization at San Miguel Electric Co-Op

COAL POWER magazine :: Operations & Maintenance >> 
San Miguel Electric Cooperative selected and installed an automatic sootblowing system for its Unit 1 to minimize clinkers in the boiler that caused semi-annual unscheduled outages. New boiler surface-cleaning equipment and intelligent cleaning software eliminated these expensive outages....

Continuous SO3 Monitoring Can Reduce Sorbent Consumption

COAL POWER magazine :: Operations & Maintenance >> 
An unintended consequence of employing selective catalytic reduction and wet flue gas desulfurization to reduce nitrogen oxide and sulfur dioxide levels at coal-fired power plants has been unwanted sulfur trioxide (SO3) emissions. Picking the right sorbent in the right amount can eliminate that problem....

Power 101: Improving the Performance of Boiler Auxiliaries, Part II

COAL POWER magazine :: Operations & Maintenance >> 
Efficient boiler operation requires boiler auxiliary equipment to operate in harmony. The air preheater, for example, though it has few moving parts, is vital to maintaining efficient boiler performance. In this second installment of our Power 101 series, we examine performance degradation caused by corrosion and fouling of the air preheater that results from the combustion of coal plus the effects of ammonia and sodium bisulfite injection for SO3 mitigation....

Flue Gas Analysis as a Furnace Diagnostic Tool

COAL POWER magazine :: Operations & Maintenance >> 
Combustion flue gas analysis has been used to optimize the boiler air/fuel ratio for decades. Measuring the amount of excess oxygen and/or carbon monoxide in combustion flue gases gives an indication of boiler efficiency and, thereby, plant operating economics. New sensors make those measurements simple and accurate....

Power 101: Improving the Performance of Boiler Auxiliaries, Part I

COAL POWER magazine :: Operations & Maintenance >> 
Boiler auxiliary equipment often receives no respect for the role it plays in maintaining efficient boiler performance. In this second installment of our Power 101 series, we examine the design and performance of the air preheater....

Pulverized Coal Pipe Testing and Balancing

COAL POWER magazine :: Operations & Maintenance >> 
If you want the most accurate test results, it's worth the extra effort to take isokinetic coal samples from coal pipes when collecting fuel and air measurements. Together, the data collected will allow more accurate balancing of coal pipes, measure fuel fineness, and improve the combustion efficiency of your steam generator....

CUT COSTS AND GO GREEN WITH THERMAL FLUID

With the World concentrating on cutting carbon emissions for sound ecological reasons and Industry working hard to save money by reducing energy bills, it is rare to find a simple and proven technology that readily meets both criteria.

Thermal Fluid Systems from Babcock Wanson have regularly shown energy savings over conventional Steam process heating of between 30-50% with reduced maintenance needs and fully automatic operation.
To learn how this technology could help your business why not request a copy of The Practical Application of Thermal Fluid Heating.

Power 101: Flue Gas Heat Recovery in Power Plants, Part III

COAL POWER magazine :: Operations & Maintenance >> 
Every power engineer must have a firm grasp of the rudiments of how fuel is processed to produce electricity in a power generation facility. With this article, we conclude our three-part series on the essentials of recovering heat from flue gas to dry and process coal, with the goal of improving overall plant operating efficiency....

Wind Integration: Does It Reduce Pollution and Greenhouse Gas Emissions?

COAL POWER magazine :: Operations & Maintenance >> 
Many claim that wind generation is beneficial because it reduces pollution emissions and does not emit carbon dioxide. This isn’t necessarily the case. When wind is introduced into a generation system that uses carbon technologies to back up the wind, it actually reduces the energy efficiency of the carbon technologies....

Improve Furnace Reducing Atmosphere Using Fuel/Air Ratio Control

COAL POWER magazine :: Operations & Maintenance >> 
Progress Energy has incorporated online combustion optimization/tuning to eliminate furnace reducing atmospheres at its Asheville Plant. The optimization project utilized individual burner airflow measurement and continuous burner coal flow measurement to adjust burner air/fuel ratios. The result: significantly improved boiler combustion....

Power 101: Flue Gas Heat Recovery in Power Plants, Part II

COAL POWER magazine :: Operations & Maintenance >> 
Every power engineer must have a firm grasp of the rudiments of how fuel is processed to produce electricity in a power generation facility. With this article, we continue our three-part series on the essentials of recovering heat from flue gas to dry and process coal, with the goal of improving overall plant operating efficiency....
