TECHNOLOGY SUMMARY Develop a very low emissions, natural gas-fired burner for new and retrofit applications to industrial and utility watertube boilers and process fluid heaters in the range of 1.2 to 35 MWth (4 to 120 X 10^6 Btu/h)
Computational Fluid Dynamics (CFD) simulations are performed to model the radiation process in natural gas fired furnaces using different gray and non-gray radiation models. Simulations of two representative furnace cases (HTAC and OXYFLAM) were performed and the computed radiative fluxes compared w...
One of the largest heat losses in high temperature furnaces is the loss of flue gas enthalpy. Currently, up to 60% of the heating value of natural gas (or any other fuel) used in high temperature furnaces is lost via the flue gases. This work discusses the benefits and technology of re-circulating t...
