    Reformer burners

    Obviously, criterion for sustained and reliable fuel combustion in burner is air/fuel metering, mixing, ignition, shaping flame, stable short lame, emissions, (see “Burners for Reformers and Cracking”). The S-M Reformer burners are selected and located in line with the type of the heater and...

    Heaters refractory dry out

    General guidelines for dry-out conventional refractory is to use 3 or 4 heating schedule. Heating rate is 30 -40°C/hr to avoid thermal stress and refr spalling and cracking . Rather use fuel gas than oil and avoid direct flame impingement. No flow in the tubes during dry-out. During dry-out...

    Fired Furnace Residual Heat

    As per some dynamic simulations you can use for the heater relief rate 45% of normal heat duty as residual refractory heat after power out. Earlier when static short-cut calculations were bused 50% was used.
