Abstract

The utility model relates to a fuel oil (gas) heating tube hot gas heating stove, which is composed of a fin combustion stove and a heating tube exchanger. The heating tube exchanger is divided into two parts by a tube sheet, the upper part of the heating tube exchanger is a hot gas generation room, the lower part of the heating tube exchanger is a convection heat exchange flue, and a seal clamping ring which is welded on the heating tube is sheathed in a socket hole of the tube sheet by an asbestos rope, which is convenient for disassembly and cleaning. The combustion heat of a combustor has radiation exchanged through a fin combustion stove and a fin, the heat is absorbed by heating tube heat absorption section in the convection heat exchange flue to have vaporization and latent heat, and the heat is discharged by a humidification water jacket smoke gas connection tube. Cold current blown by a blower forces and bumps a heating tube fin heat release section of the hot gas generation room, and the condensation latent heat is released to heat gas quickly. Hot gas encircles a hot gas annular gas channel through a hot gas guide plate along a fin combustion furnace, the radiation heat of a combustion stove wall and the fin is absorbed, and heated hot gas is discharged through a hot gas outlet. A hot gas conduit is provided with a thermocouple sensor same temperature controller, and a full automatic computer controller controls the size of combustor flame and the gas quantity of the blower to realize full automatic operation.

Description

Fuel oil (gas) heat pipe hot-blast warming stove

The utility model belongs to the heat-pipe apparatus for preparing hot air heating.

Exhausted most Boiler Steam or the hot water circuit of adopting of present civilian heating warmed oneself by fin.Also useful electric heating mode, energy secondary utilizes the thermal efficiency low, the cost height, more very, maintenance simultaneously is difficult for the area of lack of water or water quality inferiority, price height, disadvantage that the life-span is short or the like.

The purpose of this utility model provides a kind of the easily manufactured of fin combustion furnace and superconduction fin heat pipe augmentation of heat transfer of adopting, and do not have to press, pollution-free, water not, uses new heat pipe hot blast warming stove widely.

Leave the dividing plate (6) of hot blast annular passage (3) in the middle of the utility model fin combustion furnace (1) and the heat pipe exchanger (2), ring fin (4) assembly welding is on the combustion furnace outer wall, the same dividing plate of panel (5) (6) assembly welding of combustion furnace (1) has the interface of burner (7) on panel (5).Fin combustion furnace (1) is lying in the preceding bottom of heat pipe exchanger (2), and places hot blast annular passage (3).It is hot-air generation chamber (9) that heat pipe exchanger (2) is separated into top with high temperature resistant tube sheet (8), and the bottom is (10) two branch casings of heat convection flue.The same tube sheet of heat pipe (11) (8) is to inlay with the snap ring (12) of asbestos cord sealing to be enclosed within the fork round of tube sheet (8), heat pipe (11) fin heat release section all places the hot-air generation chamber (9) on tube sheet (8) top, the anterior light pipe of heat pipe (11), the endotherm section of rear portion finned tube places the S-type heat convection flue (10) of tube sheet (8) bottom, combustion product gases is taken over (13) through afterbody humidification water jacket flue gas and is discharged body of heater, offer the top cover of removing stage makeup and costume (14) of being convenient to the change and repair heat pipe at hot-air generation chamber (9) top, fin combustion furnace (1) stack shell top and hot-air generation chamber (2) top group welding arc shape hot-air guide plate (15), hot-air annular passage (3) hot-air that leads after taking over (16), hot-blast outlet is sent into place with hot-air around fin combustion furnace outer wall one circle, at heat pipe exchanger rear portion installing blower fan (17), whole heat exchange casing (18) is packed with alumina silicate insulation (19) color steel.

During the utility model work, connect power supply gentle (oil) pipe valve earlier, start blower fan (17) and burner (7), the light pipe radiation endotherm section and the fin convection current endotherm section of the heat pipe (11) of heat of high temperature in the S shape heat convection flue (10) of fin combustion furnace (1) and fin (4) and heat pipe exchanger (2) bottom of burner (7) burning absorb heat, heat pipe (11) intraductal working medium absorbs the latent heat of vaporization rapidly, the small pressure reduction of working medium in the tube, with the speed of Ultrasonic wave like speed with heat delivery to the heat pipe that places hot-air generation chamber (9) (11) fin heat release section, under blower fan (17) drives, reverse cold airflow is forced and is washed away heat pipe (11) fin heat release section, discharges the latent heat of condensation.Condensation working medium arrives heat pipe heat-absorbing section by gravity reflux, absorb the latent heat of vaporization again, vaporization, move in circles, rely on the superconduction heat transfer of heat pipe endlessly the fractional combustion heat to be passed to hot-air, hot-air circumferentially washes away combustion furnace (1) outer wall and fin (4) through guide plate (15) effect through hot blast annular passage (3) again, and hot blast is heated once more, is received by hot-blast outlet adapter (16) at last and uses the hot-air place.Combustion product gases is taken over (13) through humidification water jacket flue gas and is discharged body of heater.
