Greenhouse Gas Protocol

Oxygen steel furnace gas is obtained as a by-product of the production of steel in an oxygen furnace and is recovered on leaving the furnace. The gas is also known as converter gas, LD gas or BOS gas. The amount of patent fuel produced may, therefore, be slightly higher than the actual amount of coal consumed in the transformation process

Boiler Efficiency and Combustion | Spirax Sarco

However, all common fuels contain hydrogen, which burns with oxygen to form water, which passes up the stack as steam. The gross calorific value of the fuel includes the energy used in evaporating this water. Flue gases on steam boiler plant are not condensed, therefore the actual amount of heat available to the boiler plant is reduced.

Calorific Value of Fuels: Definition, How to Calculate

The assumption is made that any oxygen present in the fuel is already wholly in combination with hydrogen. Since it is known that in water 8 parts by mass of oxygen are combined with 1 part of hydrogen, it is customary to deduct from the total hydrogen an amount equal to 1/8 of the oxygen present, calling the remainder available hydrogen.

Military Explosives Chapter 12

Oxygen balance is an expression that is used to indicate the degree to which an explosive can be oxidized. If an explo-sive molecule contains just enough oxygen to convert all of its carbon to carbon dioxide, all of its hydrogen to water, and all of its metal to metal oxide with no excess, the mol-ecule is said to have a zero oxygen balance.

Combustion - Wikipedia

Combustion in oxygen is a chain reaction in which many distinct radical intermediates participate. The high energy required for initiation is explained by the unusual structure of the dioxygen molecule. The lowest-energy configuration of the dioxygen molecule is a stable, relatively unreactive diradical in a triplet spin state.Bonding can be described with three bonding electron pairs and two

Boiler Combustion | CleanBoiler.org

Limiting the amount of excess air entering a flame is accomplished through burner design and can be optimized through the use of oxygen trim controls. Low excess air firing can be used on most boilers and generally results in overall NOx reductions of 5-10% when firing natural gas.

Boiler Efficiency - an overview | ScienceDirect Topics

Fig. 3.11 shows a simple boiler process. Fuel and the required amount of combustion air are fed into the boiler. The fuel reacts with the oxygen in the boiler and flue gas is drawn out. Released heat is captured by the water pumped into the boiler, transforming it into the steam that flows from the boiler.

hot water raised in boilers that burn a carbon-based fuel – usually natural gas, oil or coal. In general, carbon monoxide and NOx emissions are determined by the combustion characteristics of the burner and by the fuel used. Carbon dioxide and sulphur dioxide emissions are entirely dependent on fuel's carbon and sulphur content respectively.

Combustion of Fuels - Carbon Dioxide Emission

To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7. Carbon Dioxide emission from burning a fuel can be calculated as. q CO2 = c f / h f M CO2 /M m [1]. where. q CO2 = specific CO 2 emission [kg CO2 /kWh]
