the food heating process comprises the following steps: firstly, a food supply pipe (24) to be heated continuously supplies cold water to be heated into an annular feeding cavity (90), the annular feeding cavity (90) is filled with liquid food to be heated, then the liquid food in the annular feeding cavity (90) continuously passes through a plurality of heating pipes (77) under the action of a pump and enters a discharging cavity (72), then combustion flame in a furnace cavity of a heating furnace body (22) heats the plurality of heating pipes (77), further the liquid food in the plurality of heating pipes (77) is continuously heated, and the heated water in the discharging cavity (72) continuously flows out through a heated food delivery pipe (23) under the action of the pump;
gas flow direction: the gas supply pipe (1) continuously introduces natural gas into the gas inlet cavity (18) and generates high-pressure gas along with the accumulation of the natural gas in the gas inlet cavity (18), further, the natural gas in the air inlet cavity (18) enters the air storage cavity (19) through the hard gas heat exchange pipe (29), then the high-temperature and high-pressure natural gas in the gas storage cavity (19) is respectively sprayed out from four gas nozzles of the first gas spray pipe (9), the second gas spray pipe (7), the third gas spray pipe (15) and the fourth gas spray pipe (14), then the high-temperature natural gas sprayed out of the four gas nozzles is respectively vertically sprayed to the first fire-dispersing plate (8), the second fire-dispersing plate (6), the third fire-dispersing plate (13) and the fourth fire-dispersing plate (12) at a high speed, then the natural gas sprayed to the first fire-dispersing plate (8), the second fire-dispersing plate (6), the third fire-dispersing plate (13) and the fourth fire-dispersing plate (12) is rapidly dispersed to the periphery in a water wave shape and is rapidly mixed and blended with combustion air;
flow direction of combustion air: the combustion-supporting air supply pipe (26) continuously guides combustion-supporting air into the combustion-supporting air channel (21), further the combustion-supporting air in the combustion-supporting air channel (21) is discharged to the furnace chamber in a divergent shape around through the hollow holes (17) uniformly distributed in a circumferential array, and further the combustion-supporting air scattered in the divergent shape is fully mixed with the combustion-supporting air rapidly diffused around in a water wave shape;
and (3) a combustion process: starting an electronic ignition device in the furnace chamber; four natural gas dispersing areas which are in a water wave shape and rapidly diffuse to the periphery at the positions of a first dispersing plate (8), a second dispersing plate (6), a third dispersing plate (13) and a fourth dispersing plate (12) are firstly combusted to form four flames which are rapidly expanded in a wave shape, and because the tube lengths of a first gas spray tube (9), a second gas spray tube (7), a third gas spray tube (15) and a fourth gas spray tube (14) are gradually lengthened, the four natural gas dispersing areas which are in a wave shape in the first dispersing plate (8), the second dispersing plate (6), the third dispersing plate (13) and the fourth dispersing plate (12) are not in the same longitudinal space and are uniformly distributed in the four longitudinal spaces, so that the gas and the air in the whole furnace chamber are uniformly mixed and melted with each other, the flames are uniformly distributed in the four longitudinal spaces, and stable and continuous high-temperature uniform flames are generated in the furnace chamber, further heating a plurality of heating pipes (77); the stable and continuous high-temperature uniform flame in the furnace chamber continuously heats the hard gas heat exchange tube (29) at the same time, so that the natural gas in the hard gas heat exchange tube (29) is continuously heated, high-temperature and high-pressure natural gas is formed in the gas storage cavity (19), and the natural gas sprayed out from the four gas nozzles of the first gas spray tube (9), the second gas spray tube (7), the third gas spray tube (15) and the fourth gas spray tube (14) is the high-temperature natural gas which reaches the ignition point, so that the sprayed high-temperature natural gas can be rapidly combusted when encountering oxygen in the furnace chamber, and the combustion rate is further improved;
flue gas flow direction: high-pressure flue gas generated by flame combustion in the furnace chamber enters a flue gas discharge channel (79) through a flue gas inlet (2) and is discharged to an external tail gas treatment device through a flue gas outlet pipe (25); the high-temperature flue gas passes through the flue gas exhaust passage (79) in-process, and the combustion air that flows through in the combustion air passageway (21) of outside is heated continuously, still preheats inboard gas supply pipe (1) simultaneously, consequently is the high temperature combustion air after preheating to the combustion air that is discharged to the furnace chamber all around through being the fretwork hole (17) of circumference array equipartition and is dispersed form, and then has further improved the violent degree of burning and combustion efficiency in the stove.
