High temperature combustion

WebOxy-fuel combustion is the process of burning a fuel using pure oxygen, or a mixture of oxygen and recirculated flue gas, instead of air. Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame temperatures are possible. Historically, the primary use of oxy-fuel combustion has been in welding and cutting ... WebThe combustion of the multicomponent fuel follows the principle of large fuel components [3]. The approach combines experimentally constrained, lumped reaction steps for fuel …

The approach takes advantage of the key physics underlying the high-temperature combustion of large hydrocarbon fuels [1,2]: 1. Pyrolysis/oxidative pyrolysis of the fuel occurs first followed by oxidation of the pyrolysis products; 2.

WebFormation of N2O during the combustion process is affected by two furnace-zone factors. N2O emissions are minimized when combustion temperatures are kept high (above 1475oF) and excess oxygen is kept to a minimum (less than 1 percent). Methane emissions are highest during low-temperature combustion or incomplete combustion, WebIn high-temperature oxy-fuel combustion processes, fuel and oxygen are mixed at the burner undiluted with recycled flue gas, except to motivate coal for coal-fired systems. This process can result in a high flame temperature (>4,500°F), which enhances heat transfer in the radiant zone of the boiler.
