Experience on coal reburn in a utility boiler
Reburning is an in-furnace combustion modification technology for the reduction of NOx. By staging the introduction of the fuel, an environment is created where NOx generated by the combustion of the main fuel supply is subsequently consumed by the hydrocarbon radicals arising from the reburn fuel under reducing conditions. ENEL has retrofitted unit No. 4 of Vado Ligure power station with ...

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 ...

Evaluation of the optimum efficiency of fire tubes boilers
Three-stage pirotubular boilers using gasoil C have been studied. Two boilers were connected in parallel. The data has been obtained by means of an analyser; its probe was connected at the exit of the boilers. The operation parameters considered were the injection pressure and the number of burners. As the emission of pollutants must be within the values prescribed by legislation, these are ...

Aerovit Installation - Orlén Refinery, Lithuania - Case Study
Situation BEFORE Aerovit Installation Orlen Lietuva Refinery has two boilers which are losing a considerable amount of heat due to catalyst dust build-up in the tubes. After two month of operation the boilers tubes are fully covered by catalysts dust, but Orlen ´s technicians cannot stop them for manual cleaning because it would imply the whole refinery to shut down. The diagram shows ...

The microwaves steam the beech logs – they are ready for peeling in just 8 minutes. Fully autonomous, no human intervention - Case study
The unique microwave equipment has made steaming a simple, fast and continuous process. What we’ve been dealing with The customer, a major wood processor, like many others, had been using the batch steaming method. However, he was not satisfied with the complex logistics, the long processing time and the inefficient use of staff. He therefore thought about how the whole process could be ...

Why carbon reduction and energy efficiency must be combined
With all the eyes focused on carbon emissions prior to Cancun, it’s vital not to lose sight of the need to combine carbon reduction with energy efficiency. Reducing carbon emissions is generally associated with an increase in energy efficiency. But, it is possible to reduce such carbon emissions while still operating inefficient systems. A biomass boiler, for example, reduces carbon ...

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 ...

Chemically Inclined: The Case for Clean Boilers
Boiler cleaning is something most companies don’t want to think about — if boilers are working within operational limits it’s often easier to keep up with smaller preventative maintenance (PM) tasks but put off a total chemical clean until performance starts to suffer. The problem? Once scale forms on boiler surfaces both fuel and efficiency losses quickly ramp up. Here’s ...

Attention to the use of steam boilers in the industry
In the industry, if people need to use high-temperature steam , then the steam boiler will be used; water can be heated to a quite high temperature, and generates high-temperature steam . Steam boilers and other hot water boiler are not the same , if people want to use the steam boiler, the boiler must be certified , or else once operated wrongly , then the consequences are very terrible. Steam ...

Case study - Mission Linen Supply, Santa Barbara, California, USA
“A number of years ago Sid Abma of Sidel Systems USA Inc. approached us with his Sidel SRU flue gas heat recovery unit. I think that we, like most companies, considered it; but we took no action for some time. Finally a situation developed that made it beneficial for us to try this unit. We purchased a unit and had it installed in July of 2006. A second unit is in the process of being ...
