Jun 02, 2006 · Try to keep your boilers at the highest loads possible. If you have old big boilers sitting there, get rid of one or two of them and keep just one running flat out all the time. Install other boilers that can go off very quickly and come back on very quickly for swing loads. That's the best way to keep your whole system optimally fired.
Jul 05, 2009 · Keep an optimal excess air level, generally about 20% in a coal fired boiler. Tune combustion of coal to the optimal condition. Proper distribution of combustion air at primary, secondary, and tertiary levels. Keep the required fineness of coal about 75% …
Mar 24, 2021 · 3. How to reduce the coal consumption of coal-fired boilers Improving the thermal efficiency of the boiler is to increase the effective use of heat and reduce the heat loss of the boiler. The key point is to reduce the heat loss of boiler exhaust and mechanical incomplete combustion loss, and reduce the cost of coal-fired boilers. 1.
Lower TDS feed water reduces boiler blowdown and can save energy venting though boiler blowdown. Also flash heat recovery from boiler can be planned for reducing heat loss to atmosphere. Variable frequency drives: Most of the boiler are designed for peak load requirement but average loading of boiler is normally low, Variable frequency drives helps in reducing power consumption in low load condition.
INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER
The use of boiler air volume not only affects the efficiency of the boiler, but also the excessive air volume will increase the unit consumption of the blower and induced draft fan, increase the power consumption rate of the plant, and affect the increase of coal consumption in power supply.
Ensuring maximum boiler efficiency can significantly reduce energy requirements and production costs. Key principles of efficient boiler operation: • Feed boilers with billeted wood to aid combustion • Do not unnecessarily open boiler door - this disrupts combustion • Open only 1 door when feeding boiler …
How to Run a Coal Fired Boiler at the Best Efficiency
Mar 01, 2007 · Another way to reduce energy consumption in the furnace is to pour at the coolest temperature that is practical and avoid temperature overshooting. For example, if metal that could have been poured at 2,750°F is allowed to rise less than 10% to 3,000°F, heat losses are boosted by 33%, using significantly more energy.
