Patent
·
OSTI ID:5854789
A heater for stimulating wells includes a heat shield with openings for air in the heat shield side walls, an air inlet upstream of a burner to premix the fuel and air, and a burner made up of a bundle of tubes of varying lengths to vertically spread the flame. Alternatively, to vertically spread the flame, a burner is provided in tubular form with perforations extending the length of the tube. Wireline run ignitors, using energy from batteries, are used to ignite the burners. Also, a wireline run catalytic material combined with an injected hydrogen mixture can be used for ignition.
