Combustion emissions and thermal performance impacts when replacing hydrocarbon fuels with hydrogen in industrial furnaces | Many industrial processes rely on heating that is currently achieved through combustion of fossil fuels. The industrial sector generates approximately 23 percent of the greenhouse gas emissions in the US. As infrastructure associated with production and distribution of hydrogen continues to expand, ... | ||

Reduced order model of a lime kiln for fuel switching | The lime kiln is an essential part of the causticizing loop in the kraft pulp mill. It is also the last operating unit that routinely fires fossil fuels like natural gas and fuel oil. Displacing these fossil fuels with biomass like bark or sawdust is done, as is firing lignin extracted from black li... | ||

Decarbonizing: the future of hydrogen firing | Historically, firing hydrogen fuel was only economical in certain applications outside of the power industry. Unlike other fossil fuels, hydrogen does not naturally exist as H2 and is commonly produced in hydrogen reformers and considered an energy carrier and not an energy source. Steam-methane ref... | ||

Ammonia for industrial combustion | ammonia combustion; hydrogen; methane | Many companies are investigating switching from conventional fossil fuels to "green" fuels such as hydrogen to reduce CO2 emissions. This assumes hydrogen is made by an environmentally-friendly method such as electrolysis using renewable energy. However, there are concerns with hydrogen. For example... | |

Coanda effect enhanced air assisted flare for low flow operation: cold flow CFD analysis | This paper aims at increasing the flow velocity in the flare stack by decreasing the flow diameter to solve the issue of low flow operation in the flares. A new air assisted flare design of 1m height and 15cm diameter has been tested using CFD simulation in this work. The design includes injecting a... | ||
