A method for mounting a Pilot Flame with High Heat output to a Pilot Nozzle associated with a Steam Boiler Fueled with Coal for Industrial furnaces, to PREHEAT The Oven Method, a method for generating a pilot light and a device for preheating the oven

摘要

A method and apparatus for preheating Furnace during heating of the Furnace operation. The Oven has a Steam Boiler Main fuel supply Tube surrounded by a Main combustion Air Duct Defining an annular space between the supply and The Conduit which extends in the axial direction with respect to the boiler Main Steam.A pilot Nozzle in the annular Space extends in the axial direction from the steam Boiler into the Furnace and discharge of flammable gaseous fuel injection into the Furnace through openings in the nozzle.Combustion Air Duct goes beyond the nozzle and is mixed with the fuel discharging Holes to form a combustible mixture is ignited to form the Descending Pilot Flame to heat the Furnace nozzle.The Flame is stabilized and Anchor in the pilot Nozzle through the recycling of parts of the flame and its constituents from the Interior of the oven to the nozzle to prevent the air that passes through the primary Ignition area is affected by the Air Flow Through the Through combustion Air MainThe divergence of the injected Fuel jets with respect to the axial direction at an angle between about 20 and 80, and applying to the Jets injected Fuel component of a tangential direction with respect to the axial direction so as to rotate the flame on The Axis of the Pilot.
