Water-tube or fire-tube condensing boiler, which is the better option?
When it comes to selecting the type of boiler for your specific hot water application, you are faced with the options of a condensing boiler or a conventional boiler. If you think the decisions end after making this choice, think again! If you do in fact proceed with the more efficient condensing boiler, there is another important decision to be made – what boiler design is best suited for ...

Exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant
This paper presents exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant using specific exergy costing (SPECO) methodology. Cost–balance and auxiliary equations are developed and solved. The results indicate that in the topping cycle, the boiler and the turbine contribute maximum to the formation of product cost. High value of exergoeconomic factor for the boiler ...

The “Tipping” Point of High Turndown Ratios: How much of a good thing is too much?
Boilers used for domestic water and space heating are one of the highest energy consumers in residential and commercial facilities. After the global energy crisis in the 1970s, higher fuel prices prompted the search for solutions to reduce energy consumption. Back then, conventional steam boilers were the only option available. However, these boilers were very inefficient (due in part to the ...

Steam Boiler Chemicals
Steam boilers are vessels to which heat is applied so that water is continuously converted in to steam. ‘Feed water’ is the water added to a boiler to replace that lost due to evaporation and blow down. Often steam is condensed and returned to the boiler as part of the feed water. The primary objectives in boiler design, operation and effective treatment include: efficiency in heat ...

Case study - Keeping ethanol production green
OVERVIEW Originally published in Pollution Engineering Magazine. In an effort to reduce the world’s dependence on fossil fuels, there has been a major push towards alternatives. Ethanol has been at the forefront of this movement because it reduces greenhouse gas emissions from automobiles and its production has a positive net energy balance. The homegrown fuel also reduces the need for ...

Problems of catalytic boiler safety and their role in designing and operation of gas-fired boiler
In the following paper, some problems of safety for catalytic boilers with fixed and fluidised beds are discussed. The reason is to protect the boiler from gas and fuel-air mixture explosion. For it the conditions excluding the transition from catalytic combustion to flame must be observed, and they are presented in the article for different combustible gases. A special attention has been paid to ...
