Product Details
Boiler Economizer
Coal Fuel Steel Gas Economizer For Boiler System , Economiser In Steam Power Plant
Introduction
Economiser performs a key function in providing high overall boiler thermal efficiency by recovering the low level energy from the flue gas before it is exhausted to the atmosphere. Economiser recovers the energy by heating the boiler feedwater.Economiser are basically tubular heat transfer surfaces used to preheat boiler feed water before it enters the steam drum or furnace surfaces. Economiser reduces operating costs or economise on fuel by recovering extra energy from the flue gas.
Procedure
Economisers also reduce the potential of thermal shock and strong water temperature fluctuations as the feed water enters the drum or waterwalls. Increasingly stringent environmental regulations limiting nitrogen oxides and sulfur dioxide emission can also affect economizer design. The gas-side heat transfer coefficient is much less than water side heat transfer coefficient. To compensate this, outer surface of the tubes may be finned to increase the surface area of heat transfer. The ultimate goal of economizer design is to achieve the necessary heat transfer at minimum cost. A key design criterion for economizer is maximum allowable flue gas velocity. Higher velocity provide better heat transfer and reduce capital cost.
