摘要:
A novel two-chamber design for thermal boilers is presented in this document. The boiler uses spiral-shaped tubes with conical and flat portions which form a combustion chamber. The use of a direct flame burner causes exhaust gas turbulence and increases the gas pressure in the main chamber. The high-pressure gases, which have lost their kinetic energy due to collision with spirals, leave the main chamber and enter into the secondary chamber, where their energy is used to preheat inlet water. The control of distance between spirals, the reverse flow of exhaust gases in the chambers, and the specific geometry of the spirals maximize boiler efficiency,
摘要:
A steam generator in a heat regenerative engine includes a cylindrical combustion chamber that encloses a circularly wound coil of densely bundled tubes. The tube bundle is heated by two combustion nozzle assemblies, each having an air blower, a fuel atomizer, and an igniter. The igniter burns atomized fuel that exits the atomizer and is mixed with preheated air. The flames and heat from the combustion nozzle assemblies are directed in a centrifuge within the circular combustion chamber. This cyclonic circulation of combustion gases within the combustion chamber creates higher efficiency in the engine by subjecting the coil of tubes to multiple passes of heat, thereby promoting greater heat saturation relative to the amount of fuel expended. The relatively small diameter and large surface area of the tubes in the bundle allows the water and steam in the tubes to be heated to higher temperatures and pressures within a compact space, providing a highly efficient steam generator.
