Boiler stands for Boiler and AFBC stands for Atmospheric Fluidized Bed Combustion.

• Boiler is a closed vessel in which water or other fluid is heated.

• AFBC is a type of boiler where combustion air is forced through a bed of solid particles at a high velocity.

• Boilers are commonly used in industries for steam generation.

• AFBC boilers are known for their efficiency and environmental friendliness.

Water parameters for feed water and boiler water are crucial for efficient operation and maintenance of boilers.

• Feed water parameters include pH level, dissolved oxygen content, alkalinity, and conductivity.

• Boiler water parameters include pH level, total dissolved solids (TDS), alkalinity, and hardness.

• Regular monitoring and adjustment of these parameters are essential to prevent corrosion, scale buildup, and efficienc...read more

The bed material size, coal size, and type/grade of coal are important factors in determining the efficiency of a coal-fired power plant.

• Bed material size affects the fluidization of the bed and the combustion efficiency.

• Coal size impacts the combustion rate and heat transfer within the boiler.

• The type or grade of coal determines the calorific value and ash content, affecting the overall efficiency of the plant.

• Example...read more

SFR stands for Steam Fuel Ratio, used to calculate boiler efficiency.

• SFR is calculated by dividing steam flow rate by fuel flow rate.

• Boiler efficiency can be calculated by dividing heat output by heat input.

• For example, if a boiler produces 10,000 kg/hr of steam and consumes 1,000 kg/hr of fuel, the SFR would be 10.

• Similarly, if a boiler generates 9,000 kW of heat and consumes 10,000 kW of fuel, the efficiency would be...read more

Troubleshooting in boiler and fan motor, including temperature of bearing.

• For troubleshooting in boiler, check for leaks, pressure issues, and faulty components.

• For fan motor troubleshooting, inspect for debris, loose connections, and motor overheating.

• To monitor temperature of bearing, use infrared thermometer or temperature sensors.

• Regular maintenance and cleaning can prevent issues in both boiler and fan motor.

To save the boiler in case of a power failure, alternative power sources like generators or battery backups can be used.

• Use a generator as an alternative power source to keep the boiler running during a power failure

• Install a battery backup system to provide temporary power to the boiler

• Implement an uninterruptible power supply (UPS) to ensure continuous power supply to the boiler
