APPLICOT draws upon its theoretical expertise acquired through abundant experience and an outstanding track record to design flares that reflect considerations for safety and high efficiency while meeting all kinds of requirements for plant waste gas emissions.
We confidently pursue technical development and manufacture the optimal flare burners and related equipment for the gas composition, flow rate and installation specifications of each plant.
A plant is rendered useless when burners fail to perform as required. Burner manufacturers therefore bear a heavy responsibility for burner design.
We repeatedly test furnace burners to ensure they meet requirements. By precisely balancing combustion air, fuel and equipment, we have been able to develop burners with various sizes and shapes of flame, including ultra-short flame, flat flame and radiant wall models, while at the same time achieving ultra-low NOx levels.
GLSF-Free Jet Burner of Applicot Group -the lowest NOx burner in the world – has the ability that even defies common sense of combustion theory.
As we all know, the essential elements in order that combustion take place are fuel , air volume theoretically required for burning fuel, and temperature over ignition point. In reality, if you don’t provide 1.2 to 1.3 times of the theoretically required air volume, in other words without 20% or 30% excess air, combustion becomes unstable.
In Japanese refineries and chemical plants, it is common that the fuel consumption is suppressed to the minimum necessary for plant operation by reducing air volume around to 15% excess air. If excess air is reduced further, however, it causes weaker flame and unstable combustion and continuous operation becomes at risk as a result.
That is, if residual oxygen density in exhaust gas, that is usually about 3% when excess air level is 15%, becomes less than 3%, combustion becomes unstable and flame starts to fluctuate continuously. Temperature distribution in a furnace which should be uniform also becomes uneven affecting the quality of product.
GLSF-Free Jet Burner has epoch-making performance requiring only 10% excess air and less than 2% residual oxygen density to produce stable combustion on a continuing basis. We even heard surprising feedback from our client refineries installing this burner that continuous stable combustion can be performed even with 0% excess air.
Burner performance is usually assessed by lower excess air and higher turndown ratio. GLSF-Free Jet Burner has excellent performance characteristics, not only above two elements, but also lower Nox value and more remarkable ease of use promoted by combustion stability and high turndown ratio than other manufacturer’s conventional burners.
Although GLSF-Free Jet Burner of Applicot is more expensive than other competitive products, the number of our clients is continuously increasing. Why?
One of reasons is that GLSF-Free Jet Burner can reduce the number of customer complaints on combustion that we had a lot for Nox burners. Another reason is that expendable parts for burning damage or deterioration are not required structurally. This is unthinkable about conventional burners. For GLSF Free Jet Burner, no spare-parts replacement is required and only inspection is enough for maintenance. By using this burner, not only fuel cost but also labor cost can be reduced This burner can achieve drastic reduction of running cost and maintenance cost.
In the burner industry, it is a traditional common practice that a burner itself is sold at a loss and on the other hand, spare-parts is sold thereafter to compensate for the loss. This burner, however, is changing people’s mind set from initial cost sensitive to running cost sensitive.
Backed by a wealth of neutralizing technology gained from years of experience in the thermal decomposition of waste gases and liquids generated by petrochemical plants, APPLICOT has been aggressively pursuing research, development and engineering for producing all kinds of incinerators for odoriferous gases and for liquid waste to meet the growing need to control environmental pollution.
APPLICOT incinerators can be installed with dust precipitators to trap particulates in flue gas to prevent their release into open air, neutralizers for removing highly corrosive chemical substances such as chlorinated compounds, and a system for usefully recovering heat from waste gas through an economizer to preheat combustion air or generate steam.
