Nox Osx

Dec 29, 2016 Nox App Player Mac version is officially released today. Compatibility with all versions of Mac OS. Compared with other Android emulators, Nox for Mac has a different kernal which makes it more stable and run faster. It fully release the power of your hardware and brings astounding experience. Fossil-fuel-fired power plants and vehicles together account for about 70% of total CO2 emissions in the U.S. 1 Along with CO2, these sources also release the co-pollutants sulfur dioxide (SO2) and nitrogen oxides (NOx) that harm health. Breathing either sulfur dioxide (SO2) or nitrogen oxides (NOx) for short periods (24 hrs or less) can. NOx & SOx as Pieces of an Overall Emissions Control Puzzle. Eco Power Solutions operates two of its systems – one on gas-fired boiler and the other for coal-fired – at their technology center.

1. Nox Oxides Of Nitrogen
2. Nox Oxygen
3. Nox Sox And Pm

With more and more ships traveling each day to different parts of the world, the air pollution caused by them is on the rise and is one of the major global concerns. The two main pollutants from the ship’s emission are Nitrogen oxides (NOx) and Sulphur oxides (SOx). These gases have adverse effects on the ozone layer in the troposphere area of the earth’s atmosphere which results in the green house effect and global warming.

Both NOx and SOx are combustion products that are emitted in to the environment in the form of smoke. MARPOL Annex VI is strictly followed to have the air pollution under control limits.

Nitrogen Oxides or NOx Pollution

Marine fuel in an I.C engine is burnt inside the combustion chamber by the correct mixture of fuel and air in the presence of heat or ignition source.

The ignition source in the marine engine is the compression stroke of the piston, after which, the combustion begins.

As the air mixture is 21 % Oxygen and 78% Nitrogen, nitrogen reacts with oxygen under certain engine operating conditions to form Nitrogen oxides or NOx.

What Causes NOx in Marine Engines?

• High Cylinder Temperature and Pressure during combustion proce

• Heavy Load on the engine or engine unit.

• Improper air and fuel ratio for combustion.

• High Temperature of intake or scavenge air inside the cylinder.

• Over heated cylinder jacket due to poor heat transfer by jacket cooler.

• Jacket water temperature is on the higher side.

• Bad quality of fuel used for engine.

Limits for NOx Emission For merchant vessel

-17.0 g/kwh when engine rpm (n) is less then 130 rpm.

-45.0 x n ^(-0.2) g/kwh when ‘n’ is between 130 rpm or above 130 rpm but less then 2000rpm.

-9.8 g/kwh when ‘n’ is 2000 rpm and above.

Where;

n- Rated engine speed

g/kwh- gram per kilo watt hour

rpm – revolution per minute
