However, modern equipment like high-velocity excess air
burners, ceramic fiber insulation, solid-state temperature controllers and temperature-sensing equipment make it possible to substantially reduce treatment cycles for carbon and alloy steels in a range of section sizes.
In a huge win for environmental groups, a federal judge has ordered ExxonMobil to pay nearly $20 million for spewing millions of pounds of excess air
pollution from its Houston-area industrial facilities.
As the effect of lean burn on the decrease in cooling heat loss is larger than that of EGR, it is expected that higher engine thermal efficiency can be achieved with lean burn compared to excess air
ratio of 1 condition with cooled EGR.
To combat the chances of incomplete combustion burners are always commissioned with an element of 'excess air
. Combustion is complex and there are many variables such as air temperature, humidity, barometric pressure and fuel quality that affect the whole process.
Don't swallow too much air Your main objective when trying to avoid a distended tum is to prevent getting excess air
into the system.
Seven operating parameters under investigation included bed temperature, particle size, Ca/S ratio, excess air
, circulating ratio, bed material height and secondary air ratio.
An entity related to the borrower currently owns the hotel property that abuts the site and had 118,675 s/f of excess air
The remaining excess air
is divided into two parts; most is injected through separate openings in the liner to mix with the hot combustion gas, while the remainder cools engine components downstream of the combustor.
This buildup can cause small areas of slurry tank turbulence and introduce excess air
into the slurry.
This combustion mode is operated by inducing high excess air
into cylinder so that peak combustion temperature is lower compared to stoichiometric condition which also lowers formation of the NOx emission.
The first objective for maximising efficiency is to minimise the excess air
required to maintain a clean, stable and reliable flame.
It ran with low efficiency under lower boiler load with the flue gas oxygen level as high as 16% which indicated too much excess air
. However, each boiler had two burners operating together in parallel which can actually work separately as two individual burners.
