Gas boilers work by combustion: they burn carbon-based fuel with oxygen to produce carbon dioxide and steam—exhaust gases that escape through a kind of chimney on the top or side called a flue. The trouble with this design is that lots of heat can escape with the exhaust gases.
Domestic Boiler Emission Testing Project reference: 60566063 Prepared for: Greater London Authority AECOM Executive Summary London Atmospheric Emissions Inventory (LAEI) 2013 identified emissions from domestic gas combustion as the second largest individual source of NOX pollution in London, after transport emissions.

Boilers. A gas/oil central heating boiler (heat generator) is like the engine of a car, this provides the heat that the facility needs to warm itself up. The size of the boiler is matched to the size of the facility. If the boiler is oversized, the fuel bills will be excessive. If the boiler is undersized, it may not generate enough heat in winter.
a minimum of 1 square inch net free vent area per 4,000 BTUs of gas input rating; a minimum of 1 square inch per 2,000 BTUs of gas input rating for a vent with a screen; a minimum of a 4″ duct brought from the attic or outside and terminating in the near proximity of the furnace/boiler (installation of a new furnace without outside combustion
Stable boiler operation is key to efficient, reliable, and cost-effective power generation for both utilities and industries. Back in 1999, the acquisition of Combustion Engineering (C-E) by Alstom, and then GE, added important C-E legacy boiler technology to our portfolio, effectively complementing our boiler, steam turbine and generator rotating technologies.
Condensing boiler - Wikipedia. 2019-8-18·Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
Post-combustion control Post-combustion process control generally consists of the use of baghouses and filters in the case of solid fuel firing, and selective catalytic reduction (SCR) process to reduce NOx in gas and oil fired boilers. SCR works well, which is why all vehicles have catalytic converters.
Another option is to use an economizer on the boiler, to capture the heat before it exits the stack. The most effective method is by having a boiler with multiple gas passes, in the combustion area. Also important is having the tube surface exposed as much as possible to the fire that is passing across the boiler furnace.
Stoichiometric combustion is a theoretical point where optimum levels of oxygen and fuel mix, to achieve maximum combustion efficiency for industrial boilers.

Burner Combustion Control for Boilers Boilers are often the principal steam or hot water generator system used in industrial plant or commercial heating. Consequently, they must be designed to operate efficiently and safely whilst responding rapidly to any change in demand.
Too little oxygen results in incomplete combustion creating harmful emissions. Setting the boiler to burn with excess oxygen is the normal solution to reducing emissions. SST's Zirconium Dioxide oxygen sensors can help customers optimise their boiler combustion efficiency within the oil, coal, gas and biomass boiler market.

The electrical power supply will often be a switch on a red switch plate that is located at the top of the basement stairs or near the boiler. The fuel shutoff valve is either located near the oil tank (for oil boilers) or incoming gas pipe (for gas boilers). You can also disconnect the power and fuel lines from the boiler.

A cogeneration plant adds a heat recovery boiler -- a simple "water wall" boiler which takes the thermal energy from the hot gases in the gas turbine and applies additional heat to produce superheated steam, which can then be run through a steam turbine. In some plants, a small portion of the steam is then reinjected into the combustion
Boilers combusting unprocessed natural gas may have higher SO2 emissions due to higher levels of sulfur in the natural gas. For these units, a sulfur mass balance should be used to determine SO2 emissions. Particulate Matter - Because natural gas is a gaseous fuel, filterable PM emissions are typically low. Particulate
The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas.
In part three of this five-part series on combustion control, we consider analyzing flue gas oxygen and combustibles, along with varying air, and fuel pre-combustion flows to improve combustion efficiency of industrial boilers, steam generators, furnaces, ovens, smelters and process heaters.

A boiler is a bit more complex than a forced air furnace in that it has more parts, valves, and controls. However, gas-fired boilers are fairly reliable and, when problems do occur, they are usually related to the expansion tank or water circulation pump(s).
Oil boilers perform the same way as gas boilers: oil burns inside the combustion chamber and heats up the heat exchanger, which in turn heats water. However, the main difference between oil and gas boilers is that an oil boiler requires an oil storage tank. The oil must be delivered to the home and stored in the tank until it's needed.
