• Crown Jakarta Capital Eco Management News: Energy Conservation in Boilers

    Community, Communication Design



    Energy is an indispensable resource that is required to run the economy and sustain the well being of people. Every day new discoveries are made to improve efficiency of the methods of power generation and transmission. After all, energy conservation must be our social responsibility.

    Social responsibilities for exploring, harnessing, adopting the given energy sources to obtain effective means to consume those are no less important. The rapidly developing economies of Third World countries like India, China need to generate increasing amounts of energy as they grow. Energy shortages with rising cost confront every nation, especially those aspiring for industrial development. A time has come when no resource of this planet, including energy, should be used wastefully. To achieve this ideal, the society as a whole would require collective efforts of all groups, especially between the organizations harnessing energy and the consumers of energy. And both must understand the underlying principles of energy generation and energy consumption.

    Every day new discoveries are made to improve efficiency of the methods of power generation and transmission. Some of the discoveries would fail to attract the users while some may be rejected or replaced by new claims. Such a circumstance would demand repeated explorations of energy opportunities and the way social responses can facilitate the use of new discoveries.

    Energy Conservation Opportunities

    The various energy efficiency opportunities in boiler system can be related to combustion, heat transfer, avoidable losses, high auxiliary power consumption, water quality and blowdown. Flue gases are the single most important cause of energy loss. As much as 18 to 22 percent of available energy goes up the chimney. Heat radiation and convection from boiler walls raise heat loss another 1 to 4 percent. Examining the following factors can indicate if a boiler is being run to maximize its efficiency:

    1. Stack Temperature

    The stack temperature should be as low as possible. However, it should not be so low that water vapor in the exhaust condenses on the stack walls. This is important in fuels containing signficant sulphur as low temperature can lead to sulphur dew point corrosion. Stack o temperatures greater than 200 C indicates potential for recovery of waste heat. It also indicate the scaling of heat transfer/recovery equipment and hence the urgency of taking an early shut down for water / flue side cleaning.
