Natural Gas Fired Boilers

The principal mechanism of NOx formation while firing natural gas is thermal NOx, which is very different than firing coal with a modern boiler where NOx is mostly fuel NOx. Thermal NOx occurs through the thermal disassociation and subsequent reaction of nitrogen (N2) and Oxygen (O2) molecules in the combustion air which is approximately 78% N2 and 20.9% O2.

Hydrogen boiler - Hylife Innovations

The hydrogen boiler converts hydrogen gas into heat. A catalyst in the boiler creates a reaction between low-concentrated hydrogen and oxygen in the reaction channel. The catalyst activates an oxidation process without electricity or a flame. This reaction releases enough warmth to heat an entire home. A system of heat exchangers provides hot

Measuring Natural Gas in Boiler and Furnace Applications

Two postcombustion technologies that may be applied to natural gas-fired boilers to reduce NOx emissions are selective noncatalytic reduction (SNCR) and selective catalytic reduction (SCR). The SNCR system injects ammonia (NH3) or urea into combustion flue gases (in a specific temperature zone) to reduce NOx emission. The Alternative Control Techniques (ACT) document for NOx emissions from utility boilers, maximum SNCR performance was estimated to range from 25 to 40 percent for natural gas-fired boilers.12 Performance data available from several natural gas fired utility boilers with SNCR show a 24 percent reduction in NOx for applications on wall-fired boilers and a 13 percent reduction in NOx for applications on tangential-fired boilers.11 In many situations, a boiler …

One technology that offsets the efficiency loss due to lower flame temperatures in a firetube boiler is flue gas recirculation. Although the loss of radiant heat transfer could result in an efficiency loss, the recirculated flue gases increase the mass flow through the boiler – thus the convective heat transfer in the tube passes increases.
