A steam generator is fired by a fossil fuel burner. The generator is shown as producing approximately 80% quality steam to be injected into oil wells to promote secondary recovery. The flame body from the burner is propagated along the longitudinal axis of a horizontally extended cylindrical chamber. Water and/or steam is passed through tubes mounted on the internal walls of the cylindrical chamber in order that they may absorb radiant heat from the flame body. The heat absorbing tubes are divided into groups, or sets, to establish the rate of water and/or steam flow through the tubes. The tubes within each group are extended as a plurality of reaches the length of the cylinder and are joined to each other by 180.degree. bends of that part of the tube between reaches. Each reach of each tube group is arranged on the internal wall of the cylinder to result in uniform exposure of the tube groups to the radiant heat. Each tube group is connected by a common feed water manifold and the flow into each group from the manifold is positively controlled to maintain uniformity of feed water flow through the tube groups.
