Embodiment

With reference to embodiment, the present invention is described in further detail, following examples be explanation of the invention and The invention is not limited in following examples.

Multiple-effect heater of the present invention, mainly by shell 01, inner casing 02, water jacket 03, spoiler 04, combustion Burning cylinder 05, socket combination, the flame burner 06 as thermal source are connected to the porch of combustion barrel 05 from outside to inside respectively；Will Combustion barrel 05 slightly shorter than the inwall length of water jacket 03 is sleeved among water jacket 03 and remains with space and forms circular combustion Air cavity 13, while combustion barrel 05 is shorter in length than the inwall length of water jacket 03 to possess the baffling distance of combustion gas, in water jacket 03 outside set loads onto inner casing 02 and remains with the tail gas chamber 14 that space forms annular shape, that is, allows water jacket 03 actually to be put Between gas chamber 13 and tail gas chamber 14, allow to contact thermal source simultaneously and heated heat absorption to the inner and outer wall of water jacket 03； Cover to load onto shell 01 and remain with space again in the outside of inner casing 02 and form circular heat exchanging chamber 15；In water jacket 03 The ventilating opening 09 of connection gas chamber 13 and tail gas chamber 14 is provided with one end of flame burner 06, this is logical The minimum number of air port 09 is one, while the inlet 07 and liquid outlet being connected with external working equipment are provided with water jacket 08；The tail gas chamber 14 formed between water jacket 03 and inner casing 02 is provided with spoiler 04, and spoiler 04 is central angle It is less than 270 ° of semi-annular shape more than 180 °, arrangement is around the outer wall relative misalignment interval of water jacket 03, minimum number It is two panels；An offgas outlet 10 is provided with below the end of inner casing 02, the offgas outlet 10 passes through heat exchanging chamber 15 It is in communication with the outside with shell 01 and is discharged for tail gas；The heat transferring medium being connected with external working equipment is provided with shell 01 Entrance 11 and heat transferring medium outlet 12.

During work, working media is respectively from the inlet 07 of water jacket 03 and the heat transferring medium entrance of heat exchanging chamber 15 10 are passed through wherein, start flame burner 06, flame is burnt in combustion barrel 05, and the residual flame of high temperature and combustion gas are entered Enter the gas chamber 13 that the inwall of water jacket 03 forms with combustion barrel 05, carrying out heating to the heat transferring medium in water jacket 03 makes it Heating, once warm combustion gas is dropped and has become outside the entrance inner casing 02 of ventilating opening 09 and water jacket 03 that tail gas passes through water jacket 03 The tail gas chamber 14 of wall composition, baffling in tail gas chamber 14 is directed at along spoiler 04, is continued to being exchanged heat in water jacket 03 Medium is heated, while also carries out hot friendship to the heat transferring medium in the heat exchanging chamber 15 that is made up of inner casing 02 and shell 01 Changing makes its heated heating, and tail gas is finally discharged from offgas outlet 10；Absorbed heat heating working media from water jacket 03 and changing Hot chamber 15 is passed through working equipment and carries out heat supply heating as needed after coming out.

Multiple-effect heater of the present invention, it can be Oil-combustion combusting machine as the flame burner 06 of thermal source, can It can be electric calorifier to be to use gas burner system, can also be that flue tail gas of other high temperature etc. is used as thermal source, be advantageous to remaining Recuperation of heat utilizes.

In summary, the present invention compared with prior art, has advantages below and effect：First is that heat exchange area is big, heat Efficiency high；Second is double heat exchanging chambers, can synchronously use a variety of working medias；3rd is that various heating sources can be used, supporting cleverer It is living, except using fuel oil or gas burner system, electric calorifier, flue tail gas of high temperature etc. can also be used, is advantageous to waste heat and returns Receive；4th is compact-sized compact, wide application, can be applied to industry heating, household heating, can also be applied to vehicle using as Warming and engine prewarming equipment.
