There is evidence that high levels of it can inflame the airways in our lungs and, over along period of time, affect how well our lungs work. People with asthma are particularly affected. NO 2 can also affect vegetation. NO 2 and the UK

Particulates - Wikipedia

Particulates also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM), or suspended particulate matter (SPM) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or

Ventilation (architecture) - Wikipedia

Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives.

1.4 Natural Gas Combustion - US EPA

1.4 Natural Gas Combustion 1.4.1 General1-2 Natural gas is one of the major combustion fuels used throughout the country. It is mainly used to generate industrial and utility electric power, produce industrial process steam and heat, and heat residential and commercial space. Natural gas consists of a high percentage of methane (generally above

Liquefied natural gas - Wikipedia

Liquefied natural gas (LNG) is natural gas (predominantly methane, CH 4, with some mixture of ethane, C 2 H 6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure).. LNG is odorless, colorless, non-toxic and non-corrosive.

1.4 Natural Gas Combustion

Natural gas is considered to be one of the cleanest of the commonly used fossil fuels. The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), and trace amounts of sulfur dioxide (SO2), particulate matter (PM), organic compounds, and other greenhouse gases.

How to Convert a Gas Appliance from LP to Natural Gas

Natural gas is a much lower pressure gas than propane and converting the appliance to one or the other gases requires that the differing pressure is compensated for. In other words, connecting a natural gas appliance to a propane piping system will result in appliance malfunction and possibly danger.

Boiler Efficiency - an overview | ScienceDirect Topics

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.
