Abstract
A vertical tubeless boiler relates to the generation of hot fluids. A boiler is presented with improved efficiency and capacity causing less pollution and noise wherein the water jacket, formed by inside pipe-combustion chamber inserted into the outside pipe with the upper header and the bottom header placed between and at each end of the pipes, is surrounded with hot combustion products generated in the combustion chamber by burning oil or gas. Passages are arranged to make four passes of hot combustion products. The first pass is downward below the burner head and inside the inner pipe of the water jacket. The second pass is upward by one section of the external wall of the water jacket.The third Pass is downward by two sections of the external wall of the water jacket. The fourth pass is upward by remaining section of the external wall of the water jacket. The external wall of the water jacket is conducted by fins pitched to increase the heat flow from the hot gases to the heated fluid.
The fins are wrapped around with the flue jacket which is gas tight welded to the flue dividers, the nozzle the boiler support plate and to the sleaves. The flue jacket is wrapped with ceramic fibre to insulate hot combustion products. The air for combustion is supplied through a nozzle placed between the inside pipe of the water jacket and the outside wall of the water jacket and bellow the top header of the water jacket. The burner head is radially positioned to the nozzle- air supply. The air for combustion is supplied by the centrifugal fan with radial blades.
